Title: Cutting template for a negative pressure wound therapy drape

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims the benefit of priority to U.S. Provisional Application No. 62/656,642, filed on Apr. 12, 2018, which is incorporated herein by reference in its entirety. 
    
    
     BACKGROUND 
     The present disclosure relates generally to wound therapy systems and devices, and more particularly to a cutting template for a negative pressure wound therapy drape. 
     Negative pressure wound therapy (NPWT) is a type of wound therapy that involves applying negative pressure (relative to atmospheric pressure) to a wound site to promote wound healing. Some NPWT systems surround the wound in a dressing which is sealed with a drape. The drape establishes a barrier between negative pressure and atmospheric pressure. These NPWT systems may include sensors for monitoring the negative pressure within the drape. The drape must be cut in order for these sensors to be installed. Cutting the drape may be difficult due to adherence between the drape and dressing. In some instances, the NPWT system may not operate desirably if the drape is cut incorrectly.

     DETAILED DESCRIPTION 
     Overview 
     Referring generally to the FIGURES, a cutting template for a negative pressure wound therapy (NPWT) device and components thereof is shown, according to various exemplary embodiments. The cutting template is placed on a dressing, which is placed over a tissue wound, and subsequently covered with a drape. The cutting template is configured such that a gap is formed between the dressing, a portion of the cutting template, and the drape. An edge of cutting tool may then be drawn across the drape, opposite the gap, such that the edge is located between the dressing and the cutting template, thereby cutting the drape. After the drape is cut so as to form an aperture in the drape from which the cutting template and a cutout are removed. A manifold may then be sealed to the drape about the aperture, so as to facilitate interaction of the NPWT device with the dressing within the drape. According to any of the embodiments disclosed herein, the cutting template may be formed from a suitable material, such felted or non-felted reticulated open-cell foam material, a plastic material, a rubber material, or other suitable material. The cutting templates of the present disclosure may also include a light adhesive (e.g. tacky, etc.) on the side facing away from the drape, so as to resist movement of the template on the dressing as the cutout is being made. 
     In some embodiments, the cutting template includes two annular surfaces which are offset so as to form a recess beneath a lip surface. In other embodiments, the cutting template includes a plurality of annular surfaces and a plurality of lip surfaces. These lip surfaces may form a recess along a side of the cutting template. In other embodiments, the cutting template includes two annular surfaces which are offset so as to form a recess above a lip surface. 
     The cutting template may include a slot extending radially towards a central axis thereof. The slot may facilitate cutting of the drape in a portion of the gap positioned proximate the slot. The cutting template may include a tab protruding from a top surface of the cutting template. The tab may assist a user in removing the cutting template from a dressing (e.g., after a drape has been cut, etc.). Additionally, the tab may facilitate cutting of the drape in a portion of the gap positioned proximate the tab. 
     The cutting template may include graduation marks positioned along a top surface of the cutting template. The graduation marks may facilitate measurement of a length and width of a tissue wound via rotation of the cutting tool around a tissue wound. The cutting template may include a hole through the center of the cutting template. The hole may facilitate rotation of the cutting template (e.g., around a tissue wound, etc.). The cutting template may include a dimple disposed on a bottom surface thereof. The dimple may facilitate collocation of the cutting template and in a divot in the dressing. These and other features and advantages of the cutting template are described in detail below. 
     NPWT System 
     Referring now to  FIG. 1 , a NPWT system  100  is shown, according to an exemplary embodiment. NPWT system  100  is shown to include a therapy device  102  fluidly connected to a wound site  104  via tubing  106  and a manifold  108 . Wound site  104  include a tissue wound, a wound dressing  110  that covers the tissue wound and adheres to a patient&#39;s skin, and a drape  112  that covers wound dressing  110  and manifold  108 . Drape  112  may adhere to wound dressing  110  and/or the patient&#39;s skin. Drape  112  facilitates a pressure differential between wound site  104  and a surrounding atmosphere. Wound dressing  110  may be referred to as being a dressing layer and drape  112  may be referred to as a drape layer. 
     Therapy device  102  can be configured to provide negative pressure wound therapy by reducing the pressure at wound site  104 . Therapy device  102  can draw a vacuum at wound site  104  (relative to atmospheric pressure) by removing wound exudate, air, and other fluids from wound site  104  through manifold  108  and tubing  106 . Wound exudate may include fluid that filters from a patient&#39;s circulatory system into lesions or areas of inflammation. For example, wound exudate may include water and dissolved solutes such as blood, plasma proteins, white blood cells, platelets, and red blood cells. Other fluids removed from wound site  104  may include instillation fluid previously delivered to wound site  104 . Instillation fluid can include, for example, a cleansing fluid, a prescribed fluid, a medicated fluid, an antibiotic fluid, or any other type of fluid which can be delivered to wound site  104  during wound treatment. The fluids removed from wound site  104  pass through manifold  108  and then through tubing  106  and may be collected in a canister that is configured to collect wound exudate and other fluids removed from wound site  104 . In addition to providing removing exudate, air, and other fluids from wound site  104 , tubing  106  may include separate lumens for use by therapy device  102  to measure pressure within wound site  104 . 
     Set Up of a Typical System 
     When a typical system is set up, a hole or cross shape is cut in a drape directly over a dressing. However, cutting the drape in this fashion often leads to the creation of a hole that is too large or too small for a device placed over the hole, potentially leading to blockage (e.g., a portion of the drape is sucked into the device, etc.) or leaking (e.g., a gap exists between the device and drape, etc.). As a result, these typical systems operate undesirably when the hole is too large or too small. Additionally, cutting the drape directly over the dressing may cause fragments from the dressing to become dislodged therefrom and potentially introduced into a wound site. These fragments may clog or otherwise contaminate the device. 
     Even after the drape in these typical systems has been cut, it is difficult to remove the cut portion because the drape adheres to the dressing. Typically, a forceps is used to grip the cut portion and attempts are made to separate the cut portion from the dressing. This may be particularly difficult to achieve if the drape is dense or slick. In addition to being time consuming, removing the cut portion can cause further disturbances to the dressing and wound site. 
     Set Up of a NPWT System Using an Example Cutting Template 
     Referring now to  FIGS. 2-5 , a process for setting up a NPWT system using a cutting template  200  is shown, according to an exemplary embodiment. Cutting template  200  may be generally cylindrical. The NPWT system may be set up (e.g., installed, initially configured, etc.) to begin NPWT on a tissue wound. To begin set up of the NPWT system, a dressing  202  is applied over the tissue wound. Cutting template  200  is then placed on dressing  202  such that a bottom surface  204  of cutting template  200  interfaces with a top surface  206  of dressing  202 . Cutting template  200  also includes a top surface  208  opposite bottom surface  204  and an annular surface  210  which is contiguous with both bottom surface  204  and top surface  208 . 
     Next, a drape  300  is placed over cutting template  200  and dressing  202 . Drape  300  includes a bottom surface  400  which interfaces with top surface  206  and top surface  208 . Drape  300  also includes a top surface  402  opposite bottom surface  400 . Bottom surface  400  does not substantially interface with annular surface  210 . Accordingly, a gap  404  exists between top surface  206 , bottom surface  400 , and annular surface  210 . Gap  404  may be increased, decreased, and otherwise changed based upon the configuration of annular surface  210 . For example, gap  404  is increased if annular surface  210  defines a recess therein. 
     After drape  300  is placed over cutting template  200  and dressing  202 , drape  300  is cut by an edge of a cutting tool. The cutting tool may be, for example, a scalpel, scissors (e.g., safety scissors, etc.), a blade, and other similar implements. The edge of the cutting tool may be pressed on top surface  402  opposite gap  404 , such that the edge may cut drape  300  without interfacing with cutting template  200  or dressing  202 . In this way, drape  300  may be cut without cutting dressing  202 , thereby avoiding dislodging of particles therefrom, and without marring or otherwise damaging cutting template  200 , thereby facilitating repeated usage of cutting template  200  (e.g., with a different drape, etc.). 
     As the cutting tool cuts drape  300 , an aperture  500  is formed in drape  300  and a cutout  502  is separated from drape  300 . After aperture  500  is formed, a plug  504  of dressing  202  may protrude through (e.g., stick out from, etc.) aperture  500 . Cutout  502  may be separated from cutting template  200  and discarded. A manifold, such as manifold  108 , is then adhered to drape  300  over aperture  500 . For example, the manifold may include a circular bead of adhesive which is applied to drape  300  proximate a perimeter of aperture  500 .

     Second Example Cutting Template for Use with a NPWT System 
     Referring now to  FIGS. 6-9 , a cutting template  600  is shown, according to an exemplary embodiment. Cutting template  600  is generally fastener shaped (e.g., mushroom shaped, top hat shaped, plug shaped, etc.) and is generally constructed from portions of two concentric cylinders of different diameters. Cutting template  600  is centered on a central axis A-A. In various embodiments, cutting template  600  is rotationally symmetrical about the central axis A-A. 
     Cutting template  600  includes a top surface  602  which is configured to interface with a drape, such as drape  300 . In various embodiments, top surface  602  includes a plurality of graduation marks  604 . Each graduation mark  604  corresponds with an angular location relative to the central axis A-A. Cutting template  600  also includes a hole  606  centered on the central axis A-A and extending through cutting template  600 . 
     Top surface  602  is contiguous with a first annular surface  608 . A border between top surface  602  and first annular surface  608  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. First annular surface  608  is defined by a circumference. Graduation marks  604  correspond with locations along the circumference of first annular surface  608 . For example, one graduation mark  604  may correspond with a starting point, a second graduation mark  604  may correspond with 25% of the circumference of first annular surface  608 , a third graduation mark  604  may correspond with 50% of the circumference of first annular surface  608 , and a fourth graduation mark  604  may correspond with 75% of the circumference of first annular surface  608 . Prior to covering cutting template  600  with a drape, cutting template  600  may be rolled along first annular surface  608  to measure a length along a dressing or a patient&#39;s skin using graduation marks  604 . To facilitate rolling of cutting template  600 , a user&#39;s finger or an implement may be placed through or into hole  606 . In one example, cutting template  600  may be rolled along a patient&#39;s skin around a tissue wound to determine a length and/or a width of the tissue wound. Measuring the length and/or width of the tissue wound may be frequently performed (e.g., with every change of a dressing, etc.). In this way, graduation marks  604  and hole  606  provide cutting template  600  with an additional functionality separate from facilitating cutting of a drape. 
     First annular surface  608  is contiguous with a lip surface  610 . A border between first annular surface  608  and lip surface  610  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. Lip surface  610  is contiguous with a second annular surface  612 . A border between lip surface  610  and second annular surface  612  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. Like first annular surface  608 , second annular surface  612  is centered on the central axis A-A. Second annular surface  612  is contiguous with a bottom surface  614 . A border between second annular surface  612  and bottom surface  614  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. Top surface  602  is substantially disposed along a first plane, lip surface  610  is substantially disposed along a second plane substantially parallel to the first plane, and bottom surface  614  is substantially disposed along a third plane substantially parallel to the first plane. 
     A recess  616  is formed between a first boundary defined by first annular surface  608 , a second boundary defined by lip surface  610 , a third boundary defined by second annular surface  612 , and a fourth boundary defined by bottom surface  614 . First annular surface  608  is defined by a first radius R 1  and second annular surface  612  is defined by a second radius R 2 . In some embodiments, the first radius R 1  is approximately 1.91 centimeters (cm). A difference between first radius R 1  and second radius R 2  is equal to a first width W 1  of lip surface  610 . Various values for first radius R 1  and second radius R 2  can be selected such that first width W 1  of lip surface  610  can be changed, thereby facilitating changing of recess  616 . Additionally, second annular surface  612  is defined by a first height H 1  between lip surface  610  and bottom surface  614 . In an exemplary embodiment, first height H 1  is 8 millimeters (mm). A distance between top surface  602  and lip surface  610  may be configured such that a distance from bottom surface  614  to top surface  602  is between 2 mm and 10 mm, inclusive. 
     When using cutting template  600  with an NWPT system, cutting template  600  is placed on a top surface  800  of a dressing  802 , which is covering a patient&#39;s skin. Next, a drape  804  is placed over cutting template  600  and dressing  802 . Drape  804  includes a bottom surface  806  which interfaces with top surface  602  and top surface  800 , and may at least partially interface with first annular surface  608 . However, cutting template  600  is configured such that drape  804  does not substantially interface with lip surface  610  or second annular surface  612 . Accordingly, a gap  808  exists between at least lip surface  610 , second annular surface  612 , top surface  800 , and bottom surface  806 . Gap  808  may also exist between bottom surface  806  and at least a portion of first annular surface  608 . Gap  808  may be increased, decreased, and otherwise changed based upon the configuration of recess  616 . For example, gap  808  is increased if first width W 1  of lip surface  610  is increased. 
     Drape  804  also includes a top surface  810  opposite bottom surface  806 . After drape  804  is placed over cutting template  600  and dressing  802 , drape  804  is cut by an edge of a cutting tool. The cutting tool may be, for example, a scalpel, scissors (e.g., safety scissors, etc.), a blade, and other similar implements. The edge of the cutting tool may be pressed on top surface  810  opposite gap  808 , such that the edge may cut drape  804  without interfacing with cutting template  600  or dressing  802 . In this way, drape  804  may be cut without cutting dressing  802 , thereby avoiding dislodging of particles therefrom, and without marring or otherwise damaging cutting template  600 , thereby facilitating repeated usage of cutting template  600  (e.g., with a different drape, etc.). 
     As the cutting tool cuts drape  804 , an aperture is formed in drape  804  and a cutout is separated from drape  804 . After the aperture is formed, a plug of dressing  802  may protrude through (e.g., stick out from, etc.) the aperture. The cutout may be separated from cutting template  600  and discarded. A manifold, such as manifold  108 , is then adhered to drape  804  over the aperture. For example, the manifold may include a circular bead of adhesive which is applied to drape  804  proximate a perimeter of the aperture. 
     In an exemplary embodiment, bottom surface  614  is defined by a first surface roughness and top surface  602  is defined by a second surface roughness less than the first surface roughness. The first surface roughness of bottom surface  614  may be selected such that movement of cutting template  600  relative to dressing  802  is resisted. The surface roughness of bottom surface  614  may be related to a static frictional coefficient with dressing  802 . For example, the static frictional coefficient of bottom surface  614  with dressing  802  may be less than 0.5. Similarly, the surface roughness of top surface  602  may be related to a static frictional coefficient with drape  804 . For example, the static frictional coefficient of top surface  602  with drape  804  may be greater than 0.5. 
     Third Example Cutting Template for Use with a NPWT System 
     Referring now to  FIGS. 9-11 , a cutting template  900  is shown, according to an exemplary embodiment. Cutting template  900  is generally fastener shaped (e.g., mushroom shaped, top hat shaped, plug shaped, etc.) and is generally constructed from portions of two concentric cylinders of different diameters. Cutting template  900  is centered on a central axis B-B. In various embodiments, cutting template  900  is rotationally symmetrical about the central axis B-B. 
     Cutting template  900  includes a top surface  902  which is configured to interface with a drape, such as drape  300 . In various embodiments, top surface  902  includes a plurality of graduation marks  904 . Each graduation mark  904  corresponds with an angular location relative to the central axis B-B. Cutting template  900  also includes a hole  906  centered on the central axis B-B and extending through cutting template  900 . 
     Top surface  902  is contiguous with a first annular surface  908 . A border between top surface  902  and first annular surface  908  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. First annular surface  908  is defined by a circumference. Graduation marks  904  correspond with locations along the circumference of first annular surface  908 . For example, one graduation mark  904  may correspond with a starting point, a second graduation mark  904  may correspond with 25% of the circumference of first annular surface  908 , a third graduation mark  904  may correspond with 50% of the circumference of first annular surface  908 , and a fourth graduation mark  904  may correspond with 75% of the circumference of first annular surface  908 . Prior to covering cutting template  900  with a drape, cutting template  900  may be rolled along first annular surface  908  to measure a length along a dressing or a patient&#39;s skin using graduation marks  904 . To facilitate rolling of cutting template  900 , a user&#39;s finger or an implement may be placed through or into hole  906 . In one example, cutting template  900  may be rolled along a patient&#39;s skin around a tissue wound to determine a length and/or a width of the tissue wound. Measuring the length and/or width of the tissue wound may be frequently performed (e.g., with every change of a dressing, etc.). In this way, graduation marks  904  and hole  906  provide cutting template  900  with an additional functionality separate from facilitating cutting of a drape. 
     First annular surface  908  is contiguous with a lip surface  910 . A border between first annular surface  908  and lip surface  910  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. Lip surface  910  is contiguous with a second annular surface  912 . A border between lip surface  910  and second annular surface  912  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. Like first annular surface  908 , second annular surface  912  is centered on the central axis B-B. Second annular surface  912  is contiguous with a bottom surface  914 . A border between second annular surface  912  and bottom surface  914  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. Top surface  902  is substantially disposed along a first plane, lip surface  910  is substantially disposed along a second plane substantially parallel to the first plane, and bottom surface  914  is substantially disposed along a third plane substantially parallel to the first plane. 
     A recess  916  is formed between a first boundary defined by first annular surface  908 , a second boundary defined by lip surface  910 , a third boundary defined by second annular surface  912 , and a fourth boundary defined by bottom surface  914 . First annular surface  908  is defined by a third radius R 3  and second annular surface  912  is defined by a fourth radius R 4 . A difference between third radius R 3  and fourth radius R 4  is equal to a second width W 2  of lip surface  910 . Various values for third radius R 3  and fourth radius R 4  can be selected such that second width W 2  of lip surface  910  can be changed, thereby facilitating changing of recess  916 . Additionally, second annular surface  912  is defined by a second height H 2  between lip surface  910  and bottom surface  914 . In an exemplary embodiment, second height H 2  is 8 mm. In another embodiment, second height H 2  is 6 mm A distance between top surface  902  and lip surface  910  may be configured such that a distance from bottom surface  914  to top surface  902  is between 2 mm and 10 mm, inclusive. 
     Cutting template  900  also includes a slot  918 . Slot  918  is positioned along a perimeter of cutting template  900  and facilitates the expansion of recess  916  inwards past second annular surface  912  and toward the central axis B-B. In the embodiment shown in  FIG. 9 , slot  918  is substantially U-shaped (e.g., relative to top surface  902  and bottom surface  914 , etc.). However, slot  918  may be substantially V-shaped (e.g., relative to top surface  902  and bottom surface  914 , etc.). Slot  918  is defined by a third annular surface  920  offset from second annular surface  912  by a third width W 3  greater than second width W 2 . 
     When using cutting template  900  with an NWPT system, cutting template  900  is placed on a top surface  1000  of a dressing  1002 , which is covering a patient&#39;s skin. Next, a drape  1004  is placed over cutting template  900  and dressing  1002 . Drape  1004  includes a bottom surface  1006  which interfaces with top surface  902  and top surface  1000 , and may at least partially interface with first annular surface  908 . However, cutting template  900  is configured such that drape  1004  does not substantially interface with lip surface  910  or second annular surface  912 . Accordingly, a gap  1008  exists between at least lip surface  910 , second annular surface  912 , top surface  1000 , and bottom surface  1006 . Gap  1008  may also exist between bottom surface  1006  and at least a portion of first annular surface  908 . Gap  1008  may be increased, decreased, and otherwise changed based upon the configuration of recess  916 . For example, gap  1008  is increased if second width W 2  of lip surface  910  is increased. 
     Drape  1004  also includes a top surface  1010  opposite bottom surface  1006 . After drape  1004  is placed over cutting template  900  and dressing  1002 , drape  1004  is cut by an edge of a cutting tool. The cutting tool may be, for example, a scalpel, scissors (e.g., safety scissors, etc.), a blade, and other similar implements. The edge of the cutting tool may be pressed on top surface  1010  opposite gap  1008 , such that the edge may cut drape  1004  without interfacing with cutting template  900  or dressing  1002 . In this way, drape  1004  may be cut without cutting dressing  1002 , thereby avoiding dislodging of particles therefrom, and without marring or otherwise damaging cutting template  900 , thereby facilitating repeated usage of cutting template  900  (e.g., with a different drape, etc.). 
     A user may initially cut drape  1004  by pressing the edge of the cutting tool on top surface  1010  opposite slot  918 . Gap  1008  is greatest at slot  918  due to third width W 3  being greater than second width W 2 . By pressing the edge of the cutting tool on top surface  1010  opposite slot  918 , a user may more easily cut drape  1004 . Additionally, this method of cutting drape  1004  decreases a possibility of drape  1004  adhering to cutting template  900 , and thereby facilitating more desirable cutting of drape  1004 . 
     As the cutting tool cuts drape  1004 , an aperture is formed in drape  1004  and a cutout is separated from drape  1004 . After the aperture is formed, a plug of dressing  1002  may protrude through (e.g., stick out from, etc.) the aperture. The cutout may be separated from cutting template  900  and discarded. A manifold, such as manifold  108 , is then adhered to drape  1004  over the aperture. For example, the manifold may include a circular bead of adhesive which is applied to drape  1004  proximate a perimeter of the aperture. 
     In an exemplary embodiment, bottom surface  914  is defined by a first surface roughness and top surface  902  is defined by a second surface roughness less than the first surface roughness. The first surface roughness of bottom surface  914  may be selected such that movement of cutting template  900  relative to dressing  1002  is resisted. The surface roughness of bottom surface  914  may be related to a static frictional coefficient with dressing  1002 . For example, the static frictional coefficient of bottom surface  914  with dressing  1002  may be less than 0.5. Similarly, the surface roughness of top surface  902  may be related to a static frictional coefficient with drape  1004 . For example, the static frictional coefficient of top surface  902  with drape  1004  may be greater than 0.5. 
     Fourth Example Cutting Template for Use with a NPWT System 
     Referring now to  FIGS. 12-14 , a cutting template  1200  is shown, according to an exemplary embodiment. Cutting template  1200  is generally fastener shaped (e.g., mushroom shaped, top hat shaped, plug shaped, etc.) and is generally constructed from portions of two concentric cylinders of different diameters. Cutting template  1200  is centered on a central axis C-C. In various embodiments, cutting template  1200  is rotationally symmetrical about the central axis C-C. 
     Cutting template  1200  includes a top surface  1202  which is configured to interface with a drape, such as drape  300 . In various embodiments, top surface  1202  includes a plurality of graduation marks  1204 . Each graduation mark  1204  corresponds with an angular location relative to the central axis C-C. Cutting template  1200  also includes a hole  1206  centered on the central axis C-C and extending through cutting template  1200 . 
     Top surface  1202  is contiguous with a first annular surface  1208 . A border between top surface  1202  and first annular surface  1208  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. First annular surface  1208  is defined by a circumference. Graduation marks  1204  correspond with locations along the circumference of first annular surface  1208 . For example, one graduation mark  1204  may correspond with a starting point, a second graduation mark  1204  may correspond with 25% of the circumference of first annular surface  1208 , a third graduation mark  1204  may correspond with 50% of the circumference of first annular surface  1208 , and a fourth graduation mark  1204  may correspond with 75% of the circumference of first annular surface  1208 . Prior to covering cutting template  1200  with a drape, cutting template  1200  may be rolled along first annular surface  1208  to measure a length along a dressing or a patient&#39;s skin using graduation marks  1204 . To facilitate rolling of cutting template  1200 , a user&#39;s finger or an implement may be placed through or into hole  1206 . In one example, cutting template  1200  may be rolled along a patient&#39;s skin around a tissue wound to determine a length and/or a width of the tissue wound. Measuring the length and/or width of the tissue wound may be frequently performed (e.g., with every change of a dressing, etc.). In this way, graduation marks  1204  and hole  1206  provide cutting template  1200  with an additional functionality separate from facilitating cutting of a drape. 
     First annular surface  1208  is contiguous with a lip surface  1210 . A border between first annular surface  1208  and lip surface  1210  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. Lip surface  1210  is contiguous with a second annular surface  1212 . A border between lip surface  1210  and second annular surface  1212  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. Like first annular surface  1208 , second annular surface  1212  is centered on the central axis C-C. Second annular surface  1212  is contiguous with a bottom surface  1214 . A border between second annular surface  1212  and bottom surface  1214  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. Top surface  1202  is substantially disposed along a first plane, lip surface  1210  is substantially disposed along a second plane substantially parallel to the first plane, and bottom surface  1214  is substantially disposed along a third plane substantially parallel to the first plane. 
     A recess  1216  is formed between a first boundary defined by first annular surface  1208 , a second boundary defined by lip surface  1210 , a third boundary defined by second annular surface  1212 , and a fourth boundary defined by bottom surface  1214 . First annular surface  1208  is defined by a fifth radius R 5  and second annular surface  1212  is defined by a sixth radius R 6 . A difference between fifth radius R 5  and sixth radius R 6  is equal to a fourth width W 4  of lip surface  1210 . Various values for fifth radius R 5  and sixth radius R 6  can be selected such that fourth width W 4  of lip surface  1210  can be changed, thereby facilitating changing of recess  1216 . Additionally, second annular surface  1212  is defined by a third height H 3  between lip surface  1210  and bottom surface  1214 . In an exemplary embodiment, third height H 3  is 6 mm. In another embodiment, third height H 3  is 8 mm. A distance between top surface  1202  and lip surface  1210  may be configured such that a distance from bottom surface  1214  to top surface  1202  is between 2 mm and 10 mm, inclusive. 
     Cutting template  1200  also includes a tab  1218  (e.g., protrusion, protuberance, etc.). Tab  1218  facilitates easy manipulation (e.g., grabbing, rotating, positioning, grasping, etc.) of cutting template  1200  may a user. For example, tab  1218  may be easily graspable by a user such that cutting template  1200  can be positioned on a dressing. Tab  1218  is positioned along a perimeter of cutting template  900  and facilitates the expansion of recess  1216  outwards past first annular surface  1208  and away from the central axis C-C. In the embodiment shown in  FIG. 12 , tab  1218  is substantially rectangular. Tab  1218  is defined by a second lip surface  1220 . Second lip surface  1220  is defined by a fourth height H 4  between second lip surface  1220  and bottom surface  1214 . According to various embodiments, fourth height H 4  is greater than third height H 3 . Second lip surface  1220  is also defined by an outer edge  1222  which is contiguous with second lip surface  1220 . Second lip surface  1220  is further defined by a fifth width W 5  between first annular surface  1208  and outer edge  1222 . 
     When using cutting template  1200  with an NWPT system, cutting template  1200  is placed on a top surface  1300  of a dressing  1302 , which is covering a patient&#39;s skin. Next, a drape  1304  is placed over cutting template  1200  and dressing  1302 . Drape  1304  includes a bottom surface  1306  which interfaces with top surface  1202  and top surface  1300 , and may at least partially interface with first annular surface  1208 . However, cutting template  1200  is configured such that drape  1304  does not substantially interface with lip surface  1210  or second annular surface  1212 . Accordingly, a gap  1308  exists between at least lip surface  1210 , second annular surface  1212 , top surface  1300 , and bottom surface  1306 . Gap  1308  may also exist between bottom surface  1306  and at least a portion of first annular surface  1208 . Gap  1308  may be increased, decreased, and otherwise changed based upon the configuration of recess  1216 . For example, gap  1308  is increased if fifth width W 5  of lip surface  1210  is increased. 
     Drape  1304  also includes a top surface  1310  opposite bottom surface  1306 . After drape  1304  is placed over cutting template  1200  and dressing  1302 , drape  1304  is cut by an edge of a cutting tool. The cutting tool may be, for example, a scalpel, scissors (e.g., safety scissors, etc.), a blade, and other similar implements. The edge of the cutting tool may be pressed on top surface  1310  opposite gap  1308 , such that the edge may cut drape  1304  without interfacing with cutting template  1200  or dressing  1302 . In this way, drape  1304  may be cut without cutting dressing  1302 , thereby avoiding dislodging of particles therefrom, and without marring or otherwise damaging cutting template  1200 , thereby facilitating repeated usage of cutting template  1200  (e.g., with a different drape, etc.). 
     A user may initially cut drape  1304  by pressing the edge of the cutting tool on top surface  1310  proximate tab  1218 . For example, the user may press the edge of the cutting tool on top surface  1310  underneath tab  1218 . Gap  1308  is greatest proximate tab  1218  due to tab  1218  protruding from first annular surface  1208 . By pressing the edge of the cutting tool on top surface  1310  proximate tab  1218 , a user may more easily cut drape  1304 . Additionally, this method of cutting drape  1304  decreases a possibility of drape  1304  adhering to cutting template  1200 , and thereby facilitating more desirable cutting of drape  1304 . 
     As the cutting tool cuts drape  1304 , an aperture is formed in drape  1304  and a cutout is separated from drape  1304 . After the aperture is formed, a plug of dressing  1302  may protrude through (e.g., stick out from, etc.) the aperture. The cutout may be separated from cutting template  1200  and discarded. A manifold, such as manifold  108 , is then adhered to drape  1304  over the aperture. For example, the manifold may include a circular bead of adhesive which is applied to drape  1304  proximate a perimeter of the aperture. 
     In an exemplary embodiment, bottom surface  1214  is defined by a first surface roughness and top surface  1202  is defined by a second surface roughness less than the first surface roughness. The first surface roughness of bottom surface  1214  may be selected such that movement of cutting template  1200  relative to dressing  1302  is resisted. The surface roughness of bottom surface  1214  may be related to a static frictional coefficient with dressing  1302 . For example, the static frictional coefficient of bottom surface  1214  with dressing  1302  may be less than 0.5. Similarly, the surface roughness of top surface  1202  may be related to a static frictional coefficient with drape  1304 . For example, the static frictional coefficient of top surface  1202  with drape  1304  may be greater than 0.5. 
     Fifth Example Cutting Template for Use with a NPWT System 
     Referring now to  FIGS. 15-17 , a cutting template  1500  is shown, according to an exemplary embodiment. Cutting template  1500  includes a cylindrical bottom portion and a generally frustum-shaped top portion. Cutting template  1500  is centered on a central axis D-D. In various embodiments, cutting template  1500  is rotationally symmetrical about the central axis D-D.  FIG. 16  is a cross-section of cutting template  1500  taken about a plane bisecting cutting template  1500  and intersecting the central axis D-D. 
     Cutting template  1500  includes a top surface  1502  which is configured to interface with a drape, such as drape  300 . In various embodiments, top surface  1502  includes a plurality of graduation marks  1504 . Each graduation mark  1504  corresponds with an angular location relative to the central axis D-D. Cutting template  1500  also includes a hole  1506  centered on the central axis D-D and extending through cutting template  1500 . 
     Top surface  1502  is contiguous with a first annular surface  1508 . A border between top surface  1502  and first annular surface  1508  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. As shown in  FIG. 15 , first annular surface  1508  is rounded. However, first annular surface  1508  may be beveled, chamfered, filleted, or otherwise similarly shaped. Additionally, first annular surface  1508  may include flat portions in addition to any rounded, beveled, chamfered, filleted, or otherwise similar shaped portions. 
     First annular surface  1508  is contiguous with a first lip surface  1510 . A border between first annular surface  1508  and first lip surface  1510  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. First lip surface  1510  extends from first annular surface  1508  inwards (e.g., towards the central axis D-D, etc.) and downwards (e.g., away from top surface  1502 , etc.). 
     First lip surface  1510  is contiguous with a second lip surface  1512 . A border between first lip surface  1510  and second lip surface  1512  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. Second lip surface  1512  extends from first lip surface  1510  outwards (e.g., away from the central axis D-D, etc.) and downwards (e.g., away from top surface  1502 , etc.). 
     Second lip surface  1512  is contiguous with a third lip surface  1514 . A border between second lip surface  1512  and third lip surface  1514  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. Third lip surface  1514  extends from second lip surface  1512  outwards (e.g., away from the central axis D-D, etc.) and upwards (e.g., towards top surface  1502 , etc.). 
     Third lip surface  1514  is contiguous with a second annular surface  1516 . A border between third lip surface  1514  and second annular surface  1516  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. Like first annular surface  1508 , second annular surface  1516  is centered on the central axis D-D. Second annular surface  1516  is contiguous with a bottom surface  1518 . A border between second annular surface  1516  and bottom surface  1518  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. Top surface  1502  is substantially disposed along a first plane and bottom surface  1518  is substantially disposed along a second plane substantially parallel to the first plane. 
     Second annular surface  1516  is defined by a circumference. Graduation marks  1504  correspond with locations along the circumference of second annular surface  1516 . For example, one graduation mark  1504  may correspond with a starting point, a second graduation mark  1504  may correspond with 25% of the circumference of second annular surface  1516 , a third graduation mark  1504  may correspond with 50% of the circumference of second annular surface  1516 , and a fourth graduation mark  1504  may correspond with 75% of the circumference of second annular surface  1516 . Prior to covering cutting template  1500  with a drape, cutting template  1500  may be rolled along second annular surface  1516  to measure a length along a dressing or a patient&#39;s skin using graduation marks  1504 . To facilitate rolling of cutting template  1500 , a user&#39;s finger or an implement may be placed through or into hole  1506 . In one example, cutting template  1500  may be rolled along a patient&#39;s skin around a tissue wound to determine a length and/or a width of the tissue wound. Measuring the length and/or width of the tissue wound may be frequently performed (e.g., with every change of a dressing, etc.). In this way, graduation marks  1504  and hole  1506  provide cutting template  1500  with an additional functionality separate from facilitating cutting of a drape. 
     A recess  1520  is formed between a first boundary defined by first lip surface  1510 , a second boundary defined by second lip surface  1512 , a third boundary defined by third lip surface  1514 , and a fourth boundary defined by a first border between first annular surface  1508  and first lip surface  1510  and a second border between third lip surface  1514  and second annular surface  1516 . First lip surface  1510  is defined by a sixth width W 6 , second lip surface  1512  is defined by a seventh width W 7 , and third lip surface  1514  is defined by an eighth width W 8 . In various embodiments, sixth width W 6  is approximately equal to eighth width W 8 . Additionally, first annular surface  1508  is defined by a seventh radius R 7  and second annular surface  1516  is defined by an eighth radius R 8  greater than seventh radius R 7 . Various values for sixth width W 6 , seventh width W 7 , eighth width W 8 , seventh radius R 7 , and eighth radius R 8  can be selected to facilitate changing of recess  1520 . Additionally, second lip surface  1512  is defined by a fifth height H 5  between (i) a boundary between second lip surface  1512  and first lip surface  1510  and (ii) bottom surface  1518 . Second lip surface  1512  is also defined by a sixth height H 6  between (i) a boundary between second lip surface  1512  and third lip surface  1514  and (ii) bottom surface  1518 . In various embodiments, one of fifth height H 5  and sixth height H 6  is 8 mm. In some embodiments, one of fifth height H 5  and sixth height H 6  is 6 mm. A distance between top surface  1502  and a boundary between a boundary between second lip surface  1512  and third lip surface  1514  may be configured such that a distance from bottom surface  1518  to top surface  1502  is between 5 mm and 10 mm, inclusive. 
     When using cutting template  1500  with an NWPT system, cutting template  1500  is placed on a top surface  1700  of a dressing  1702 , which is covering a patient&#39;s skin. Next, a drape  1704  is placed over cutting template  1500  and dressing  1702 . Drape  1704  includes a bottom surface  1706  which interfaces with top surface  1502  and top surface  1700 , and may at least partially interface with first annular surface  1508 . 
     Cutting template  1500  is configured such that drape  1704  does not substantially interface with first lip surface  1510 , second lip surface  1512 , or third lip surface  1514 . Accordingly, a first gap  1708  exists between at least first lip surface  1510 , second lip surface  1512 , or third lip surface  1514 . First gap  1708  may be increased, decreased, and otherwise changed based upon the configuration of recess  1520 . For example, first gap  1708  is increased if sixth width W 6 , seventh width W 7 , or eighth width W 8  is increased. 
     Additionally, cutting template  1500  is configured such that drape  1704  does not substantially interface with at least a portion of second annular surface  1516 . Accordingly, a second gap  1710  exists between at least a portion of second annular surface  1516 , top surface  1700 , and bottom surface  1706 . Second gap  1710  may be increased, decreased, and otherwise changed based upon the configuration of recess  1520 . 
     Drape  1704  also includes a top surface  1712  opposite bottom surface  1706 . After drape  1704  is placed over cutting template  1500  and dressing  1702 , drape  1704  is cut by an edge of a cutting tool. The cutting tool may be, for example, a scalpel, scissors (e.g., safety scissors, etc.), a blade, and other similar implements. The edge of the cutting tool may be pressed on top surface  1712  opposite first gap  1708 , such that the edge may cut drape  1704  without interfacing with cutting template  1500  or dressing  1702 . As drape  1704  is cut, the edge of the cutting tool may be positioned between first lip surface  1510  and third lip surface  1514 , and may be positioned adjacent second lip surface  1512 . In this way, drape  1704  may be cut without cutting dressing  1702 , thereby avoiding dislodging of particles therefrom, and without marring or otherwise damaging cutting template  1500 , thereby facilitating repeated usage of cutting template  1500  (e.g., with a different drape, etc.). Second gap  1710  may minimize adherence of drape  1704  to cutting template  1500 , thereby facilitating more desirable cutting of drape  1704 . 
     In some embodiments, first lip surface  1510 , second lip surface  1512 , and third lip surface  1514  are configured such that recess  1520  is configured to receive an edge of a target cutting tool. For example, cutting template  1500  may be specifically configured to receive an edge of a scalpel. 
     As the cutting tool cuts drape  1704 , an aperture is formed in drape  1704  and a cutout is separated from drape  1704 . After the aperture is formed, a plug of dressing  1702  may protrude through (e.g., stick out from, etc.) the aperture. The cutout may be separated from cutting template  1500  and discarded. A manifold, such as manifold  108 , is then adhered to drape  1704  over the aperture. For example, the manifold may include a circular bead of adhesive which is applied to drape  1704  proximate a perimeter of the aperture. 
     In an exemplary embodiment, bottom surface  1518  is defined by a first surface roughness and top surface  1502  is defined by a second surface roughness less than the first surface roughness. The first surface roughness of bottom surface  1518  may be selected such that movement of cutting template  1500  relative to dressing  1702  is resisted. The surface roughness of bottom surface  1518  may be related to a static frictional coefficient with dressing  1702 . For example, the static frictional coefficient of bottom surface  1518  with dressing  1702  may be less than  0 . 5 . Similarly, the surface roughness of top surface  1502  may be related to a static frictional coefficient with drape  1704 . For example, the static frictional coefficient of top surface  1502  with drape  1704  may be greater than 0.5. 
     Sixth Example Cutting Template for Use with a NPWT System 
     Referring now to  FIGS. 18-20 , a cutting template  1800  is shown, according to an exemplary embodiment. Cutting template  1800  is generally fastener shaped (e.g., mushroom shaped, top hat shaped, plug shaped, etc.) and is generally constructed from portions of two concentric cylinders of different diameters. Cutting template  1800  is centered on a central axis E-E. In various embodiments, cutting template  1800  is rotationally symmetrical about the central axis E-E.  FIG. 19  is a cross-section of cutting template  1800  taken about a plane bisecting cutting template  1800  and intersecting the central axis E-E. 
     Cutting template  1800  includes a top surface  1802  which is configured to interface with a drape, such as drape  300 . In various embodiments, top surface  1802  includes a plurality of graduation marks  1804 . Each graduation mark  1804  corresponds with an angular location relative to the central axis E-E. Cutting template  1800  also includes a hole  1806  centered on the central axis E-E and extending through cutting template  1800 . 
     Top surface  1802  is contiguous with a first annular surface  1808 . A border between top surface  1802  and first annular surface  1808  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. First annular surface  1808  is contiguous with a first lip surface  1810 . A border between first annular surface  1808  and first lip surface  1810  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. First lip surface  1810  extends from first annular surface  1808  outwards (e.g., away from the central axis E-E, etc.). In various embodiments, first lip surface  1810  extends substantially orthogonally from first annular surface  1808 . In some embodiments, first lip surface  1810  is disposed along a first plane which is substantially parallel to a second plane upon which top surface  1802  is disposed along. 
     First lip surface  1810  is contiguous with a second annular surface  1812 . A border between first lip surface  1810  and second annular surface  1812  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. Second annular surface  1812  extends from first lip surface  1810  towards a plane upon which top surface  1802  is disposed. In various embodiments, second annular surface  1812  extends orthogonally from first lip surface  1810 . In some embodiments, second annular surface  1812  is substantially concentric with first annular surface  1808 . 
     Second annular surface  1812  is contiguous with a second lip surface  1814 . A border between second annular surface  1812  and second lip surface  1814  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. As shown in  FIG. 18 , second lip surface  1814  is rounded. However, second lip surface  1814  may be beveled, chamfered, filleted, or otherwise similarly shaped. Additionally, second lip surface  1814  may include flat portions in addition to any rounded, beveled, chamfered, filleted, or otherwise similar shaped portions. Second lip surface  1814  extends from second annular surface  1812  outwards (e.g., away from the central axis E-E, etc.). 
     Second lip surface  1814  is contiguous with a third annular surface  1816 . A border between second lip surface  1814  and third annular surface  1816  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. Third annular surface  1816  extends from second lip surface  1814  away from a plane upon which top surface  1802  is disposed. In some embodiments, third annular surface  1816  is substantially concentric with first annular surface  1808 . Third annular surface  1816  is contiguous with a bottom surface  1818 . A border between third annular surface  1816  and bottom surface  1818  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. Top surface  1802  is substantially disposed along a first plane and bottom surface  1818  is substantially disposed along a second plane substantially parallel to the first plane. 
     Third annular surface  1816  is defined by a circumference. Graduation marks  1804  correspond with locations along the circumference of third annular surface  1816 . For example, one graduation mark  1804  may correspond with a starting point, a second graduation mark  1804  may correspond with 25% of the circumference of third annular surface  1816 , a third graduation mark  1804  may correspond with 50% of the circumference of third annular surface  1816 , and a fourth graduation mark  1804  may correspond with 75% of the circumference of third annular surface  1816 . Prior to covering cutting template  1800  with a drape, cutting template  1800  may be rolled along third annular surface  1816  to measure a length along a dressing or a patient&#39;s skin using graduation marks  1804 . To facilitate rolling of cutting template  1800 , a user&#39;s finger or an implement may be placed through or into hole  1806 . In one example, cutting template  1800  may be rolled along a patient&#39;s skin around a tissue wound to determine a length and/or a width of the tissue wound. Measuring the length and/or width of the tissue wound may be frequently performed (e.g., with every change of a dressing, etc.). In this way, graduation marks  1804  and hole  1806  provide cutting template  1800  with an additional functionality separate from facilitating cutting of a drape. 
     A recess  1820  is formed between a first boundary defined by first annular surface  1808 , the first lip surface  1810 , the second annular surface  1812 , and a fourth boundary defined between the second lip surface  1814  and the first annular surface  1808 . First lip surface  1810  is defined by a ninth width W 9 . Additionally, first annular surface  1808  is defined by a ninth radius R 9  and third annular surface  1816  is defined by a tenth radius R 10  greater than ninth radius R 9 . Various values for ninth radius R 9  and tenth radius R 10  can be selected to facilitate changing of ninth width W 9 . Additionally, second lip surface  1814  is defined by a seventh height H 7  between a top edge  1822  of second lip surface  1814  and first lip surface  1810 . In various embodiments, seventh height H 7  is 8 mm. In some embodiments, seventh height H 7  is 6 mm. A distance between top surface  1802  and top edge  1822  may be configured such that a distance from bottom surface  1818  to top surface  1802  is between 2 mm and 10 mm, inclusive. 
     When using cutting template  1800  with an NWPT system, cutting template  1800  is placed on a top surface  2000  of a dressing  2002 , which is covering a patient&#39;s skin. Next, a drape  2004  is placed over cutting template  1800  and dressing  2002 . Drape  2004  includes a bottom surface  2006  which interfaces with top surface  1802  and top surface  2000 , and may at least partially interface with second lip surface  1814  (e.g., with top edge  1822 , etc.). 
     Cutting template  1800  is configured such that drape  2004  does not substantially interface with first annular surface  1808 , first lip surface  1810 , second annular surface  1812 , or third annular surface  1816 . Accordingly, a first gap  2008  exists between at least first annular surface  1808 , first lip surface  1810 , and second annular surface  1812 . First gap  2008  may be increased, decreased, and otherwise changed based upon the configuration of recess  1820 . For example, first gap  2008  is increased if ninth width W 9  or seventh height H 7  is increased. 
     Additionally, cutting template  1800  is configured such that drape  2004  does not substantially interface with at least a portion of third annular surface  1816 . Accordingly, a second gap  2010  exists between at least a portion of third annular surface  1816 , top surface  2000 , and bottom surface  2006 . Second gap  2010  may be increased, decreased, and otherwise changed based upon the configuration of recess  1820 . 
     Drape  2004  also includes a top surface  2012  opposite bottom surface  2006 . After drape  2004  is placed over cutting template  1800  and dressing  2002 , drape  2004  is cut by an edge of a cutting tool. The cutting tool may be, for example, a scalpel, scissors (e.g., safety scissors, etc.), a blade, and other similar implements. The edge of the cutting tool may be pressed on top surface  2012  opposite first gap  2008 , such that the edge may cut drape  2004  without interfacing with cutting template  1800  or dressing  2002 . As drape  2004  is cut, the edge of the cutting tool may be positioned between first annular surface  1808  and the second annular surface  1812 , and may be positioned adjacent first lip surface  1810 . In this way, drape  2004  may be cut without cutting dressing  2002 , thereby avoiding dislodging of particles therefrom, and without marring or otherwise damaging cutting template  1800 , thereby facilitating repeated usage of cutting template  1800  (e.g., with a different drape, etc.). Second gap  2010  may minimize adherence of drape  2004  to cutting template  1800 , thereby facilitating more desirable cutting of drape  2004 . 
     In some embodiments, first annular surface  1808 , first lip surface  1810 , and second annular surface  1812  are configured such that recess  1820  is configured to receive an edge of a target cutting tool. For example, cutting template  1800  may be specifically configured to receive an edge of a scalpel. 
     As the cutting tool cuts drape  2004 , an aperture is formed in drape  2004  and a cutout is separated from drape  2004 . After the aperture is formed, a plug of dressing  2002  may protrude through (e.g., stick out from, etc.) the aperture. The cutout may be separated from cutting template  1800  and discarded. A manifold, such as manifold  108 , is then adhered to drape  2004  over the aperture. For example, the manifold may include a circular bead of adhesive which is applied to drape  2004  proximate a perimeter of the aperture. 
     In an exemplary embodiment, bottom surface  1818  is defined by a first surface roughness and top surface  1802  is defined by a second surface roughness less than the first surface roughness. The first surface roughness of bottom surface  1818  may be selected such that movement of cutting template  1800  relative to dressing  2002  is resisted. The surface roughness of bottom surface  1818  may be related to a static frictional coefficient with dressing  2002 . For example, the static frictional coefficient of bottom surface  1818  with dressing  2002  may be less than 0.5. Similarly, the surface roughness of top surface  1802  may be related to a static frictional coefficient with drape  2004 . For example, the static frictional coefficient of top surface  1802  with drape  2004  may be greater than 0.5. 
     Seventh Example Cutting Template for Use with a NPWT System 
     Referring now to  FIGS. 21-23 , a cutting template  2100  is shown, according to an exemplary embodiment. Cutting template  2100  is generally fastener shaped (e.g., mushroom shaped, top hat shaped, plug shaped, etc.) and is generally constructed from portions of two concentric cylinders of different diameters. Cutting template  2100  is centered on a central axis F-F. In various embodiments, cutting template  2100  is rotationally symmetrical about the central axis F-F.  FIG. 22  is a cross-section of cutting template  2100  taken about a plane bisecting cutting template  2100  and intersecting the central axis F-F. 
     Cutting template  2100  includes a top surface  2102  which is configured to interface with a drape, such as drape  300 . In various embodiments, top surface  2102  includes a plurality of graduation marks  2104 . Each graduation mark  2104  corresponds with an angular location relative to the central axis F-F. Cutting template  2100  also includes a hole  2106  centered on the central axis F-F and extending through cutting template  2100 . 
     Top surface  2102  is contiguous with a first annular surface  2108 . A border between top surface  2102  and first annular surface  2108  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. First annular surface  2108  is contiguous with a first lip surface  2110 . A border between first annular surface  2108  and first lip surface  2110  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. First lip surface  2110  extends from first annular surface  2108  outwards (e.g., away from the central axis F-F, etc.). In various embodiments, first lip surface  2110  extends substantially orthogonally from first annular surface  2108 . In some embodiments, first lip surface  2110  is disposed along a first plane which is substantially parallel to a second plane upon which top surface  2102  is disposed along. 
     First lip surface  2110  is contiguous with a second annular surface  2112 . A border between first lip surface  2110  and second annular surface  2112  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. Second annular surface  2112  extends from first lip surface  2110  towards a plane upon which top surface  2102  is disposed. In various embodiments, second annular surface  2112  extends orthogonally from first lip surface  2110 . In some embodiments, second annular surface  2112  is substantially concentric with first annular surface  2108 . 
     Second annular surface  2112  is contiguous with a second lip surface  2114 . A border between second annular surface  2112  and second lip surface  2114  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. As shown in  FIG. 21 , second lip surface  2114  is rounded. However, second lip surface  2114  may be beveled, chamfered, filleted, or otherwise similarly shaped. Additionally, second lip surface  2114  may include flat portions in addition to any rounded, beveled, chamfered, filleted, or otherwise similar shaped portions. Second lip surface  2114  extends from second annular surface  2112  outwards (e.g., away from the central axis F-F, etc.). 
     Second lip surface  2114  is contiguous with a third annular surface  2116 . A border between second lip surface  2114  and third annular surface  2116  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. Third annular surface  2116  extends from second lip surface  2114  away from a plane upon which top surface  2102  is disposed. In some embodiments, third annular surface  2116  is substantially concentric with first annular surface  2108 . Third annular surface  2116  is contiguous with a bottom surface  2118 . A border between third annular surface  2116  and bottom surface  2118  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. Top surface  2102  is substantially disposed along a first plane and bottom surface  2118  is substantially disposed along a second plane substantially parallel to the first plane. 
     Third annular surface  2116  is defined by a circumference. Graduation marks  2104  correspond with locations along the circumference of third annular surface  2116 . For example, one graduation mark  2104  may correspond with a starting point, a second graduation mark  2104  may correspond with 25% of the circumference of third annular surface  2116 , a third graduation mark  2104  may correspond with 50% of the circumference of third annular surface  2116 , and a fourth graduation mark  2104  may correspond with 75% of the circumference of third annular surface  2116 . Prior to covering cutting template  2100  with a drape, cutting template  2100  may be rolled along third annular surface  2116  to measure a length along a dressing or a patient&#39;s skin using graduation marks  2104 . To facilitate rolling of cutting template  2100 , a user&#39;s finger or an implement may be placed through or into hole  2106 . In one example, cutting template  2100  may be rolled along a patient&#39;s skin around a tissue wound to determine a length and/or a width of the tissue wound. Measuring the length and/or width of the tissue wound may be frequently performed (e.g., with every change of a dressing, etc.). In this way, graduation marks  2104  and hole  2106  provide cutting template  2100  with an additional functionality separate from facilitating cutting of a drape. 
     A recess  2120  is formed between a first boundary defined by first annular surface  2108 , the first lip surface  2110 , the second annular surface  2112 , and a fourth boundary defined between the second lip surface  2114  and the first annular surface  2108 . First lip surface  2110  is defined by a tenth width W 10 . Additionally, first annular surface  2108  is defined by an eleventh radius R 11  and third annular surface  2116  is defined by a twelfth radius R 12  greater than eleventh radius R 11 . Various values for eleventh radius R 11  and twelfth radius R 12  can be selected to facilitate changing of tenth width W 10 . Additionally, second lip surface  2114  is defined by an eighth height H 8  between a top edge  2122  of second lip surface  2114  and first lip surface  2110 . In various embodiments, eighth height H 8  is 8 mm. In some embodiments, eighth height H 8  is 6 mm. A distance between top surface  2102  and top edge  2122  may be configured such that a distance from bottom surface  2118  to top surface  2102  is between 2 mm and 10 mm, inclusive. 
     When using cutting template  2100  with an NWPT system, cutting template  2100  is placed on a top surface  2300  of a dressing  2302 , which is covering a patient&#39;s skin. Next, a drape  2304  is placed over cutting template  2100  and dressing  2302 . Drape  2304  includes a bottom surface  2306  which interfaces with top surface  2102  and top surface  2300 , and may at least partially interface with second lip surface  2114  (e.g., with top edge  2122 , etc.). 
     Cutting template  2100  is configured such that drape  2304  does not substantially interface with first annular surface  2108 , first lip surface  2110 , second annular surface  2112 , or third annular surface  2116 . Accordingly, a first gap  2308  exists between at least first annular surface  2108 , first lip surface  2110 , and second annular surface  2112 . First gap  2308  may be increased, decreased, and otherwise changed based upon the configuration of recess  2120 . For example, first gap  2308  is increased if tenth width Wio or eighth height H 8  is increased. 
     Additionally, cutting template  2100  is configured such that drape  2304  does not substantially interface with at least a portion of third annular surface  2116 . Accordingly, a second gap  2310  exists between at least a portion of third annular surface  2116 , top surface  2300 , and bottom surface  2306 . Second gap  2310  may be increased, decreased, and otherwise changed based upon the configuration of recess  2120 . 
     Drape  2304  also includes a top surface  2312  opposite bottom surface  2306 . After drape  2304  is placed over cutting template  2100  and dressing  2302 , drape  2304  is cut by an edge of a cutting tool. The cutting tool may be, for example, a scalpel, scissors (e.g., safety scissors, etc.), a blade, and other similar implements. The edge of the cutting tool may be pressed on top surface  2312  opposite first gap  2308 , such that the edge may cut drape  2304  without interfacing with cutting template  2100  or dressing  2302 . As drape  2304  is cut, the edge of the cutting tool may be positioned between first annular surface  2108  and the second annular surface  2112 , and may be positioned adjacent first lip surface  2110 . In this way, drape  2304  may be cut without cutting dressing  2302 , thereby avoiding dislodging of particles therefrom, and without marring or otherwise damaging cutting template  2100 , thereby facilitating repeated usage of cutting template  2100  (e.g., with a different drape, etc.). Second gap  2310  may minimize adherence of drape  2304  to cutting template  2100 , thereby facilitating more desirable cutting of drape  2304 . 
     In some embodiments, first annular surface  2108 , first lip surface  2110 , and second annular surface  2112  are configured such that recess  2120  is configured to receive an edge of a target cutting tool. For example, cutting template  2100  may be specifically configured to receive an edge of a scalpel. 
     As the cutting tool cuts drape  2304 , an aperture is formed in drape  2304  and a cutout is separated from drape  2304 . After the aperture is formed, a plug of dressing  2302  may protrude through (e.g., stick out from, etc.) the aperture. The cutout may be separated from cutting template  2100  and discarded. A manifold, such as manifold  108 , is then adhered to drape  2304  over the aperture. For example, the manifold may include a circular bead of adhesive which is applied to drape  2304  proximate a perimeter of the aperture. 
     In an exemplary embodiment, bottom surface  2118  is defined by a first surface roughness and top surface  2102  is defined by a second surface roughness less than the first surface roughness. The first surface roughness of bottom surface  2118  may be selected such that movement of cutting template  2100  relative to dressing  2302  is resisted. The surface roughness of bottom surface  2118  may be related to a static frictional coefficient with dressing  2302 . For example, the static frictional coefficient of bottom surface  2118  with dressing  2302  may be less than  0 . 5 . Similarly, the surface roughness of top surface  2102  may be related to a static frictional coefficient with drape  2304 . For example, the static frictional coefficient of top surface  2102  with drape  2304  may be greater than 0.5. 
     Eighth Example Cutting Template for use with a NPWT System 
     Referring now to  FIGS. 24-26 , a cutting template  2400  is shown, according to an exemplary embodiment. Cutting template  2400  is generally fastener shaped (e.g., mushroom shaped, top hat shaped, plug shaped, etc.) and is generally constructed from portions of two concentric cylinders of different diameters. Cutting template  2400  is centered on a central axis G-G. In various embodiments, cutting template  2400  is rotationally symmetrical about the central axis G-G. 
     Cutting template  2400  includes a top surface  2402  which is configured to interface with a drape, such as drape  300 . In various embodiments, top surface  2402  includes a plurality of graduation marks  2404 . Each graduation mark  2404  corresponds with an angular location relative to the central axis G-G. Cutting template  2400  does not include a hole, such as the hole  606 . Instead, cutting template  2400  includes a dimple  2406  (e.g., projection, protrusion, protuberance, etc.). As will be explained in more detail herein, dimple  2406  is configured to be received within a depression in a dressing to collocate cutting template  2400  and the dressing. 
     Top surface  2402  is contiguous with a first annular surface  2408 . A border between top surface  2402  and first annular surface  2408  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. First annular surface  2408  is defined by a circumference. Graduation marks  2404  correspond with locations along the circumference of first annular surface  2408 . For example, one graduation mark  2404  may correspond with a starting point, a second graduation mark  2404  may correspond with 25% of the circumference of first annular surface  2408 , a third graduation mark  2404  may correspond with 50% of the circumference of first annular surface  2408 , and a fourth graduation mark  2404  may correspond with 75% of the circumference of first annular surface  2408 . Prior to covering cutting template  2400  with a drape, cutting template  2400  may be rolled along first annular surface  2408  to measure a length along a dressing or a patient&#39;s skin using graduation marks  2404 . To facilitate rolling of cutting template  2400 , a user&#39;s fingers can pinch cutting template  2400  (e.g., with one finger on top surface  2402  and one finger on a bottom surface of cutting template  2400 , etc.). In one example, cutting template  2400  may be rolled along a patient&#39;s skin around a tissue wound to determine a length and/or a width of the tissue wound. Measuring the length and/or width of the tissue wound may be frequently performed (e.g., with every change of a dressing, etc.). In this way, graduation marks  2404  provides cutting template  2400  with an additional functionality separate from facilitating cutting of a drape. Dimple  2406  may assist a user in locating a center point of cutting template  2400  such that the user may rotate cutting template  2400  about central axis G-G. 
     First annular surface  2408  is contiguous with a lip surface  2410 . A border between first annular surface  2408  and lip surface  2410  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. Lip surface  2410  is contiguous with a second annular surface  2412 . A border between lip surface  2410  and second annular surface  2412  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. Like first annular surface  2408 , second annular surface  2412  is centered on the central axis G-G. Second annular surface  2412  is contiguous with a bottom surface  2414 . A border between second annular surface  2412  and bottom surface  2414  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. Top surface  2402  is substantially disposed along a first plane, lip surface  2410  is substantially disposed along a second plane substantially parallel to the first plane, and bottom surface  2414  is substantially disposed along a third plane substantially parallel to the first plane. 
     A recess  2416  is formed between a first boundary defined by first annular surface  2408 , a second boundary defined by lip surface  2410 , a third boundary defined by second annular surface  2412 , and a fourth boundary defined by bottom surface  2414 . First annular surface  2408  is defined by a thirteenth radius R 13  and second annular surface  2412  is defined by a fourteenth radius R 14 . A difference between thirteenth radius R 13  and fourteenth radius R 14  is equal to an eleventh width W 11  of lip surface  2410 . Various values for thirteenth radius R 13  and fourteenth radius R 14  can be selected such that eleventh width W 11  of lip surface  2410  can be changed, thereby facilitating changing of recess  2416 . Additionally, second annular surface  2412  is defined by a ninth height H 9  between lip surface  2410  and bottom surface  2414 . In an exemplary embodiment, ninth height H 9  is 8 mm. In another embodiment, ninth height H 9  is 6 mm. A distance between top surface  2402  and lip surface  2410  may be configured such that a distance from bottom surface  2414  to top surface  2402  is between 2 mm and 10 mm, inclusive. 
     When using cutting template  2400  with an NWPT system, cutting template  2400  is placed on a top surface  2600  of a dressing  2602 , which is covering a patient&#39;s skin. Dressing  2602  includes a depression  2604 . In some applications, depression  2604  is pre-formed (e.g., from a manufacturer of dressing  2602 , etc.) in dressing  2602 . In other applications, depression  2604  is formed by a user (e.g., using an implement, etc.). Depression  2604  is located at a target location on dressing  2602  so as to facilitate location of a manifold, such as manifold  108 , on dressing  2602  at the target location. Depression  2604  and dimple  2406  are configured to collocate cutting template  2400  on dressing  2602 . In various embodiments, dimple  2406  is sized and configured to be received in depression  2604 . In some embodiments, depression  2604  is sized and configured to receive dimple  2406 . 
     After dimple  2406  has been received in depression  2604 , drape  2606  is placed over cutting template  2400  and dressing  2602 . Drape  2606  includes a bottom surface  2608  which interfaces with top surface  2402  and top surface  2600 , and may at least partially interface with first annular surface  2408 . However, cutting template  2400  is configured such that drape  2606  does not substantially interface with lip surface  2410  or second annular surface  2412 . Accordingly, a gap  2610  exists between at least lip surface  2410 , second annular surface  2412 , top surface  2600 , and bottom surface  2608 . Gap  2610  may also exist between bottom surface  2608  and at least a portion of first annular surface  2408 . Gap  2610  may be increased, decreased, and otherwise changed based upon the configuration of recess  2416 . For example, gap  2610  is increased if eleventh width W 11  of lip surface  2410  is increased. 
     Drape  2606  also includes a top surface  2612  opposite bottom surface  2608 . After drape  2606  is placed over cutting template  2400  and dressing  2602 , drape  2606  is cut by an edge of a cutting tool. The cutting tool may be, for example, a scalpel, scissors (e.g., safety scissors, etc.), a blade, and other similar implements. The edge of the cutting tool may be pressed on top surface  2612  opposite gap  2610 , such that the edge may cut drape  2606  without interfacing with cutting template  2400  or dressing  2602 . In this way, drape  2606  may be cut without cutting dressing  2602 , thereby avoiding dislodging of particles therefrom, and without marring or otherwise damaging cutting template  2400 , thereby facilitating repeated usage of cutting template  2400  (e.g., with a different drape, etc.). 
     As the cutting tool cuts drape  2606 , an aperture is formed in drape  2606  and a cutout is separated from drape  2606 . After the aperture is formed, a plug of dressing  2602  may protrude through (e.g., stick out from, etc.) the aperture. The cutout may be separated from cutting template  2400  and discarded. A manifold, such as manifold  108 , is then adhered to drape  2606  over the aperture. For example, the manifold may include a circular bead of adhesive which is applied to drape  2606  proximate a perimeter of the aperture. 
     In an exemplary embodiment, bottom surface  2414  is defined by a first surface roughness and top surface  2402  is defined by a second surface roughness less than the first surface roughness. The first surface roughness of bottom surface  2414  may be selected such that movement of cutting template  2400  relative to dressing  2602  is resisted. The surface roughness of bottom surface  2414  may be related to a static frictional coefficient with dressing  2602 . For example, the static frictional coefficient of bottom surface  2414  with dressing  2602  may be less than 0.5. Similarly, the surface roughness of top surface  2402  may be related to a static frictional coefficient with drape  2606 . For example, the static frictional coefficient of top surface  2402  with drape  2606  may be greater than 0.5. 
     Ninth Example Cutting Template for Use with a NPWT System 
     Referring now to  FIGS. 27-29 , a cutting template  2700  is shown, according to an exemplary embodiment. Cutting template  2700  is generally hourglass shaped and is generally constructed from portions of two concentric cylinders of different diameters. Cutting template  2700  is centered on a central axis H-H. In various embodiments, cutting template  2700  is rotationally symmetrical about the central axis H-H. 
     Cutting template  2700  includes a top surface  2702  which is configured to interface with a drape, such as drape  300 . In various embodiments, top surface  2702  includes a plurality of graduation marks, such as graduation marks  604 , a hole, such as hole  606 , or a dimple, such as dimple  2406 . Top surface  2702  is contiguous with a first annular surface  2704 . A border between top surface  2702  and first annular surface  2704  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. 
     First annular surface  2704  is contiguous with a first lip surface  2706 . A border between first annular surface  2704  and first lip surface  2706  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. First lip surface  2706  is contiguous with a second annular surface  2708 . A border between first lip surface  2706  and second annular surface  2708  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. Second annular surface  2708  is contiguous with a second lip surface  2710 . A border between second annular surface  2708  and second lip surface  2710  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. Second lip surface  2710  is contiguous with a third annular surface  2712 . A border between second lip surface  2710  and third annular surface  2712  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. Third annular surface  2712  is contiguous with a bottom surface  2714 . A border between third annular surface  2712  and bottom surface  2714  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. First annular surface  2704 , second annular surface  2708 , and third annular surface  2712  are centered on the central axis H-H. Top surface  2702  is substantially disposed along a first plane and bottom surface  2714  is substantially disposed along a second plane substantially parallel to the first plane. 
     A recess  2716  is formed between a first boundary defined by first annular surface  2704 , a second boundary defined by first lip surface  2706 , a third boundary defined by second annular surface  2708 , a fourth boundary defined by second lip surface  2710 , and a fifth boundary defined by third annular surface  2712 . First annular surface  2704  is defined by a fifteenth radius R 15  and second annular surface  2708  is defined by a sixteenth radius R 16 . In some embodiments, fifteenth radius R 15  is equal to 4.5 cm and sixteenth radius R 16  is equal to 4.3 cm. A difference between fifteenth radius R 15  and sixteenth radius R 16  is equal to a twelfth width Wit of second annular surface  2708 . Various values for fifteenth radius R 15  and sixteenth radius R 16  can be selected such that twelfth width W 12  of second annular surface  2708  can be changed, thereby facilitating changing of recess  2716 . Additionally, cutting template  2700  is defined by a tenth height H 10  between top surface  2702  and bottom surface  2714 . In an exemplary embodiment, tenth height H 10  is 2.5 mm. In another embodiment, tenth height H 10  is 6 mm. In yet another embodiment, tenth height H 10  is 8 mm Tenth height H 10  may be between 2 mm and 10 mm, inclusive. In some embodiments, twelfth width W 12  is 1 mm. 
     When using cutting template  2700  with an NWPT system, cutting template  2700  is placed on a top surface  2900  of a dressing  2902 , which is covering a patient&#39;s skin. Drape  2904  is then placed over cutting template  2700  and dressing  2902 . Drape  2904  includes a bottom surface  2906  which interfaces with top surface  2702  and top surface  2900 , and may at least partially interface with first annular surface  2704 . However, cutting template  2700  is configured such that drape  2904  does not substantially interface with first lip surface  2706 , second annular surface  2708 , or second lip surface  2710 . Accordingly, a gap  2908  exists between at least first lip surface  2706 , second annular surface  2708 , second lip surface  2710 , top surface  2900 , bottom surface  2906 , and third annular surface  2712 . Gap  2908  may also exist between bottom surface  2906  and at least a portion of first annular surface  2704 . Gap  2908  may be increased, decreased, and otherwise changed based upon the configuration of recess  2716 . For example, gap  2908  is increased if the twelfth width W 12  is increased. 
     Drape  2904  also includes a top surface  2910  opposite bottom surface  2906 . After drape  2904  is placed over cutting template  2700  and dressing  2902 , drape  2904  is cut by an edge of a cutting tool. The cutting tool may be, for example, a scalpel, scissors (e.g., safety scissors, etc.), a blade, and other similar implements. The edge of the cutting tool may be pressed on top surface  2910  opposite gap  2908 , such that the edge may cut drape  2904  without interfacing with cutting template  2700  or dressing  2902 . In this way, drape  2904  may be cut without cutting dressing  2902 , thereby avoiding dislodging of particles therefrom, and without marring or otherwise damaging cutting template  2700 , thereby facilitating repeated usage of cutting template  2700  (e.g., with a different drape, etc.). 
     As the cutting tool cuts drape  2904 , an aperture is formed in drape  2904  and a cutout is separated from drape  2904 . After the aperture is formed, a plug of dressing  2902  may protrude through (e.g., stick out from, etc.) the aperture. The cutout may be separated from cutting template  2700  and discarded. A manifold, such as manifold  108 , is then adhered to drape  2904  over the aperture. For example, the manifold may include a circular bead of adhesive which is applied to drape  2904  proximate a perimeter of the aperture. 
     In an exemplary embodiment, bottom surface  2714  is defined by a first surface roughness and top surface  2702  is defined by a second surface roughness less than the first surface roughness. The first surface roughness of bottom surface  2714  may be selected such that movement of cutting template  2700  relative to dressing  2902  is resisted. The surface roughness of bottom surface  2714  may be related to a static frictional coefficient with dressing  2902 . For example, the static frictional coefficient of bottom surface  2714  with dressing  2902  may be less than  0 . 5 . Similarly, the surface roughness of top surface  2702  may be related to a static frictional coefficient with drape  2904 . For example, the static frictional coefficient of top surface  2702  with drape  2904  may be greater than 0.5. 
     Tenth Example Cutting Template for Use with a NPWT System 
     Referring now to  FIG. 30 , a cutting template  3000  is shown, according to an exemplary embodiment. Cutting template  3000  is generally cylindrical. Cutting template  3000  is centered on a central axis I-I. In various embodiments, cutting template  3000  is rotationally symmetrical about the central axis I-I. 
     Cutting template  3000  includes a top surface  3002  which is configured to interface with a drape, such as drape  300 . In various embodiments, top surface  3002  includes a plurality of graduation marks  3004 . Each graduation mark  3004  corresponds with an angular location relative to the central axis I-I. Cutting template  3000  also includes a hole  3006  centered on the central axis I-I and extending through cutting template  3000 . 
     Top surface  3002  is contiguous with an annular surface  3008 . A border between top surface  3002  and annular surface  3008  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. Annular surface  3008  is defined by a circumference. Graduation marks  3004  correspond with locations along the circumference of annular surface  3008 . For example, one graduation mark  3004  may correspond with a starting point, a second graduation mark  3004  may correspond with 25% of the circumference of annular surface  3008 , a third graduation mark  3004  may correspond with 50% of the circumference of annular surface  3008 , and a fourth graduation mark  3004  may correspond with 75% of the circumference of annular surface  3008 . Prior to covering cutting template  3000  with a drape, cutting template  3000  may be rolled along annular surface  3008  to measure a length along a dressing or a patient&#39;s skin using graduation marks  3004 . To facilitate rolling of cutting template  3000 , a user&#39;s finger or an implement may be placed through or into hole  3006 . In one example, cutting template  3000  may be rolled along a patient&#39;s skin around a tissue wound to determine a length and/or a width of the tissue wound. Measuring the length and/or width of the tissue wound may be frequently performed (e.g., with every change of a dressing, etc.). In this way, graduation marks  3004  and hole  3006  provide cutting template  3000  with an additional functionality separate from facilitating cutting of a drape. 
     Annular surface  3008  is contiguous with a bottom surface  3010 . A border between annular surface  3008  and bottom surface  3010  may be beveled, chamfered, rounded, filleted, or otherwise similarly shaped. Top surface  3002  is substantially disposed along a first plane and bottom surface  3010  is substantially disposed along a second plane substantially parallel to the first plane. 
     Annular surface  3008  is defined by a seventeenth radius R 17 . In some embodiments, the seventeenth radius R 17  is approximately 3.5 cm. Hole  3006  is defined by an eighteenth radius R 18 . In some embodiments, the eighteenth radius R 18  is approximately 3 mm Additionally, annular surface  3008  is defined by an eleventh H 11  between top surface  3002  and bottom surface  3010 . In an exemplary embodiment, eleventh height H 11  is 3 mm. 
     When using cutting template  3000  with an NWPT system, cutting template  3000  is placed on a top surface of a dressing, which is covering a patient&#39;s skin. Next, a drape is placed over cutting template  3000  and the dressing. The drape includes a bottom surface which interfaces with top surface  3002  and the top surface of the dressing, and may at least partially interface with annular surface  3008 . Accordingly, a gap exists between at least a portion of annular surface  3008 , the top surface of the dressing, and the bottom surface of the drape. The gap may be increased, decreased, and otherwise changed based upon the configuration of annular surface  3008 . 
     The drape also includes a top surface opposite the bottom surface of the drape. After the drape is placed over cutting template  3000  and the dressing, the drape is cut by an edge of a cutting tool. The cutting tool may be, for example, a scalpel, scissors (e.g., safety scissors, etc.), a blade, and other similar implements. The edge of the cutting tool may be pressed on the top surface of the drape opposite the gap, such that the edge may cut the drape without interfacing with cutting template  3000  or the dressing. In this way, the drape may be cut without cutting the dressing, thereby avoiding dislodging of particles therefrom, and without marring or otherwise damaging cutting template  3000 , thereby facilitating repeated usage of cutting template  3000  (e.g., with a different drape, etc.). 
     As the cutting tool cuts the drape, an aperture is formed in the drape and a cutout is separated from the drape. After the aperture is formed, a plug of the dressing may protrude through (e.g., stick out from, etc.) the aperture. The cutout may be separated from cutting template  3000  and discarded. A manifold, such as manifold  108 , is then adhered to the drape over the aperture. For example, the manifold may include a circular bead of adhesive which is applied to the drape proximate a perimeter of the aperture. 
     In an exemplary embodiment, bottom surface  3010  is defined by a first surface roughness and top surface  3002  is defined by a second surface roughness less than the first surface roughness. The first surface roughness of bottom surface  3010  may be selected such that movement of cutting template  3000  relative to the dressing is resisted. The surface roughness of bottom surface  3010  may be related to a static frictional coefficient with the dressing.
