Title: Magnetically coupled power delivery for surgical implants

Description:
PRIORITY CLAIM 
     This application claims the benefit of priority of U.S. Provisional Patent Application Ser. No. 63/137,841 titled “MAGNETICALLY COUPLED POWER DELIVERY FOR SURGICAL IMPLANTS,” filed on Jan. 15, 2021, whose inventors are Austin Xavier Rodeheaver, Todd Taber, John Briant, Grant Corthorn, Rob May, Martin Orrell, Trevor Penhallurick, David Pooley and Catherine Wyman, which is hereby incorporated by reference in its entirety as though fully and completely set forth herein. 
    
    
     TECHNICAL FIELD 
     The invention set forth in the appended claims relates generally to eye surgery. More particularly, but without limitation, the claimed subject matter relates to systems, apparatuses, and methods for inserting an implant into an eye. 
     BACKGROUND 
     The human eye can suffer a number of maladies causing mild deterioration to complete loss of vision. While contact lenses and eyeglasses can compensate for some ailments, ophthalmic surgery may be required for others. In some instances, implants may be beneficial or desirable. For example, an intraocular lens may replace a clouded natural lens within an eye to improve vision. 
     While the benefits of intraocular lenses and other implants are known, improvements to delivery systems, components, and processes continue to improve outcomes and benefit patients. 
     BRIEF SUMMARY 
     New and useful systems, apparatuses, and methods for eye surgery are set forth in the appended claims. Illustrative embodiments are also provided to enable a person skilled in the art to make and use the claimed subject matter. 
     For example, some embodiments may comprise or consist essentially of an apparatus for delivering an implant, such as an intraocular lens, using hydraulic pressure or fluid flow. In more particular examples, the apparatus may comprise a rigid plunger for advancing an implant. Some embodiments may additionally comprise a bore through the rigid plunger, which can allow a working fluid to advance the implant into the eye via hydraulic pressure in a second phase. For example, a hollow rigid plunger can be used to first advance an intraocular lens to a point that a seal is created about the intraocular lens within a delivery lumen. The lens may then be hydraulically advanced to delivery by passing a working fluid through the hollow bore of the plunger. 
     In some embodiments, a powered drive module may be advantageous for advancing the plunger. For example, a drive module may comprise a drive shaft, which can be operated by a battery-powered motor to advance the plunger. Some embodiments of the drive shaft may be magnetically coupled to the motor, allowing the motor, battery, and other reusable electronic components to be completely sealed. In more particular examples, concentric or complementary rings of magnets may be used to couple the motor to the drive shaft. The motor can rotate the outer magnetic ring, which can rotate the inner magnetic ring. In some embodiments, the drive shaft may comprise a lead screw, which can be advanced or retracted by rotation of the inner magnetic ring. 
     More generally, an apparatus for operating an implant delivery device may comprise a lead screw, a lead nut threaded to the lead screw, a follower coupled to the lead nut, a driver magnetically coupled to the follower, a containment seal between the driver and the follower, and a motor coupled to the driver. A containment seal can fluidly isolate the driver from the follower. In more particular embodiments, the apparatus may comprise a lead sleeve that couples the follower to the lead nut. For example, the lead sleeve may comprise an open cylinder configured to receive at least a portion of the lead screw. In some embodiments, the follower may comprise a first magnetic rotor, and the driver may comprise a second magnetic rotor. The second magnetic rotor may have an open cylinder disposed concentrically around the first magnetic rotor in some embodiments. Some embodiments of the follower or the first magnetic rotor may comprise a first plurality of magnets, and the driver or second magnetic rotor may comprise a second plurality of magnets. The first plurality of magnets may be disposed in a cylindrical array, and the second plurality of magnets may be disposed in a cylindrical array around the first plurality of magnets. The first plurality of magnets and the second plurality of magnets may be arranged with alternating polarity in some embodiments. 
     In other embodiments, an apparatus for delivering an implant to an eye may comprise a nozzle, an actuator, a motor magnetically coupled to the actuator, and a containment seal that fluidly isolates the motor from the actuator. The motor may be configured to operate the actuator to eject the implant through the nozzle. 
     In more particular embodiments, an apparatus for delivering an implant to an eye may comprise a nozzle having a delivery lumen, an implant bay coupled to the nozzle, and an actuator. A follower may be coupled to the actuator, and a driver may be magnetically coupled to the follower. A containment seal may be disposed between the driver and the follower. The driver may be coupled to a motor, which can be configured to operate the driver to move the follower to cause the actuator to engage the implant in the implant bay and move the implant through the delivery lumen. The actuator may comprise a housing and a plunger operable to move linearly within the housing, and the follower may be coupled to the plunger. 
     A method for using an implant delivery apparatus may comprise providing an implant in an implant bay of the implant delivery apparatus, magnetically coupling a drive shaft to a drive module of the implant delivery apparatus, coupling the drive shaft to an actuator of the implant delivery apparatus, operating the drive module to advance the implant from the implant bay through a delivery lumen with the drive shaft and the actuator, removing the drive shaft from the drive module, and sterilizing the drive module. 
     Features, elements, and aspects described in the context of some embodiments may also be omitted, combined, or replaced by alternative features. Other features, objectives, advantages, and a preferred mode of making and using the claimed subject matter are described in greater detail below with reference to the accompanying drawings of illustrative embodiments.

     DESCRIPTION OF EXAMPLE EMBODIMENTS 
     The following description of example embodiments provides information that enables a person skilled in the art to make and use the subject matter set forth in the appended claims, but it may omit certain details already well known in the art. The following detailed description is, therefore, to be taken as illustrative and not limiting. 
     The example embodiments may also be described herein with reference to spatial relationships between various elements or to the spatial orientation of various elements depicted in the attached drawings. In general, such relationships or orientation assume a frame of reference consistent with or relative to a patient in a position to receive an implant. However, as should be recognized by those skilled in the art, this frame of reference is merely a descriptive expedient rather than a strict prescription. 
       FIG. 1  is a schematic diagram of a system  100  that can insert an implant into an eye. In some embodiments, the system  100  may comprise two or more modules, which can be configured to be coupled and decoupled as appropriate for storage, assembly, use, and disposal. For example, as illustrated in  FIG. 1 , some embodiments of the system  100  may include a nozzle  105 , an implant bay  110  coupled to the nozzle  105 , and an actuator  115  coupled to the implant bay  110 . In some embodiments, the system  100  may additionally comprise a drive module  120  configured to engage the actuator  115 . 
     The nozzle  105  generally comprises a tip adapted for insertion through an incision into an eye. The size of the tip may be adapted to surgical requirements and techniques as needed. For example, small incisions are generally preferable to reduce or minimize healing times. Incisions of less than 3 millimeters may be preferable in some instances, and the tip of the nozzle  105  may have a width of less than 3 millimeters in some embodiments. 
     The implant bay  110  generally represents a wide variety of apparatuses that are suitable for storing an implant prior to delivery into an eye. In some embodiments, the implant bay  110  may additionally or alternatively be configured to prepare an implant for delivery. For example, some embodiments of the implant bay  110  may be configured to be actuated by a surgeon or other operator to prepare an implant for delivery by subsequent action of the actuator  115 . In some instances, the implant bay  110  may be configured to actively deform, elongate, extend, or otherwise manipulate features of the implant before the implant is advanced into the nozzle  105 . For example, the implant bay  110  may be configured to extend or splay one or more features, such as haptics, of an intraocular lens. 
     The actuator  115  is generally configured to advance an implant from the implant bay  110  into the nozzle  105 , and thereafter from the nozzle  105  through an incision and into an eye. 
     The drive module  120  is generally operable to energize the actuator  115 . In some examples, the drive module  120  may be operated by electrical, mechanical, hydraulic, or pneumatic power, or combinations thereof, or in some other manner. In some instances, the drive module  120  may be operated manually. According to other implementations, the drive module  120  may be an automated system. 
     In general, components of the system  100  may be coupled directly or indirectly. For example, the nozzle  105  may be directly coupled to the implant bay  110  and may be indirectly coupled to the actuator  115  through the implant bay  110 . Coupling may include fluid, mechanical, thermal, electrical, or chemical coupling (such as a chemical bond), or some combination of coupling in some contexts. For example, the actuator  115  may be mechanically coupled to the drive module  120  and may be mechanically and fluidly coupled to the nozzle  105 . In some embodiments, components may also be coupled by virtue of physical proximity, being integral to a single structure, or being formed from the same piece of material. 
       FIG. 2  is a schematic diagram of an example of the actuator  115 , illustrating additional details that may be associated with some embodiments. The actuator  115  of  FIG. 2  generally comprises a housing  205  and a plunger  210  disposed within the housing  205 . The plunger  210  is generally comprised of a substantially rigid material, such as a medical grade polymer material. In the example of  FIG. 2 , the actuator  115  further comprises a bore  215  through the plunger  210 , and a drive interface  220  configured to couple with the drive module  120  ( FIG. 1 ). A plunger seal  225  may be disposed within the housing  205  and coupled to the plunger  210 . A drive seal  230  may also be disposed within the housing  205 . 
     As illustrated in the example of  FIG. 2 , the drive seal  230  may be disposed between the plunger seal  225  and the drive interface  220 , and a fluid chamber  235  may be defined within the housing  205  between the plunger seal  225  and the drive seal  230 . In the example configuration of  FIG. 2 , the plunger seal  225  is configured to provide a fluid seal across the housing  205  and substantially prevent movement of fluid from the fluid chamber  235  to the bore  215 . The drive seal  230  may also be configured to provide a fluid seal across the housing  205  and substantially prevent movement of fluid from the fluid chamber  235  to the drive interface  220 . 
     The housing  205  of  FIG. 2  further comprises a plunger interface  240  and a bypass channel  245  disposed between the plunger interface  240  and the drive interface  220 . The bypass channel  245  may take various forms. For example, the bypass channel  245  may comprise a protrusion in the housing  205 , as illustrated in  FIG. 2 . In other examples, the bypass channel  245  may comprise a groove or recess in the inner surface of the housing  205 . In some embodiments, the bypass channel  245  may comprise a plurality of channels. For example, a plurality of channels may be disposed circumferentially around the housing  205  in some embodiments. 
     The plunger  210  generally has a first end  250  and a second end  255 , wherein the first end  250  is generally disposed adjacent to the plunger interface  240 . The bore  215  generally passes through the plunger  210  longitudinally from the first end  250  to the second end  255 . 
     In some embodiments, the actuator  115  may additionally comprise a nozzle seal  260  and a bypass seal  265 . Each of the nozzle seal  260  and the bypass seal  265  may be generally configured to create a seal between a portion of the plunger  210  and the housing  205  to substantially prevent movement of fluid past the seal. As illustrated in the example of  FIG. 2 , one or both of the nozzle seal  260  and the bypass seal  265  may be ring seals, such as an O-ring, disposed circumferentially around a portion of the plunger  210 . In other examples, an umbrella seal may be suitable. In more particular embodiments, the nozzle seal  260  may be disposed proximate to the first end  250  of the plunger  210 , and the bypass seal  265  may be disposed proximate to the second end  255  of the plunger  210 . 
     The drive interface  220  of  FIG. 2  comprises a cap  270  and an aperture  275 . The cap  270  may be coupled to an end of the housing  205  to retain the drive seal  230  and other components within the housing  205 . 
       FIG. 3  is an assembly view of another example of the actuator  115  of  FIG. 1 , illustrating additional details that may be associated with some embodiments. For example, the housing  205  of  FIG. 3  comprises a hollow cylinder, which can receive the plunger  210 , the plunger seal  225 , and the drive seal  230 .  FIG. 3  also illustrates an example of an implant interface  305 , which may be coupled to the first end  250  of the plunger  210  in some embodiments. In the example of  FIG. 3 , the plunger  210  and the plunger seal  225  may be inserted into the housing  205 , and then a suitable working fluid may be added before inserting the drive seal  230  and attaching the cap  270  to the housing  205 . 
       FIG. 4  is an isometric view of the actuator  115  of  FIG. 3 , as assembled. As illustrated in the example of  FIG. 4 , some embodiments of the plunger interface  240  may comprise an opening in the housing  205  and one or more locking tabs  405 . The implant interface  305  and at least a portion of the plunger  210  may extend through the plunger interface  240 . The nozzle seal  260  of  FIG. 4  comprises at least one O-ring disposed around the plunger  210  adjacent to the first end  250 . As seen in the example of  FIG. 4 , the bore  215  may define an opening in the first end  250 . In some embodiments, the opening may be centrally disposed through the first end  250 , and the implant interface  305  may be coupled to the plunger  210  adjacent to the opening in the first end  250 . The implant interface  305  may comprise a notch  410 , which may be configured to engage an implant. 
       FIG. 5  is an isometric view of an example of the drive module  120  of  FIG. 1 , illustrating additional details that may be associated with some embodiments. For example, the drive module  120  of  FIG. 5  comprises a housing  505 , a user interface  510 , and a control switch  515 . In some embodiments, the user interface  510  may comprise one or more visual output devices, such as light-emitting diodes  520 , which can indicate various operating states. In other examples, the user interface  510  may comprise a display screen, such as a liquid-crystal display. Additionally, or alternatively, the user interface  510  may comprise one or more audio output devices, tactile output devices, or both. The housing  505  may define an actuator interface  525 , which may be configured to be coupled to the actuator  115 , for example. An example of a drive shaft  530  is also illustrated in the example of  FIG. 5 . In general, the drive shaft  530  may move through the actuator interface  525 . 
       FIG. 6  is an isometric view of the drive module  120  of  FIG. 5  with the housing  505  removed to illustrate additional details that may be associated with some embodiments. As illustrated in  FIG. 6 , some embodiments of the drive shaft  530  may comprise a lead screw  605  and a lead nut  610 , which may be threaded onto the lead screw  605 . The drive shaft  530  may additionally comprise a follower  615 , which may be magnetically coupled to a driver  620 . The driver  620  may be coupled to a motor  625 . For example, in some embodiments, a drive belt  630  may couple the motor  625  to the driver  620  as illustrated in the example of  FIG. 6 . 
       FIG. 7  is an isometric view of the drive shaft  530  and the driver  620  of  FIG. 6 , illustrating additional details that may be associated with some embodiments. For example, the follower  615  may be coupled to the lead nut  610 . In more particular embodiments, the drive shaft  530  may comprise a lead sleeve  705 , which can couple the follower  615  to the lead nut  610  as illustrated in the example of  FIG. 7 . The lead sleeve  705  of  FIG. 7  generally comprises an open cylinder configured to receive at least a portion of the lead screw  605 . 
       FIG. 8  is a section view of the drive shaft  530  of  FIG. 7 , taken along line  8 - 8 , illustrating additional details that may be associated with some embodiments. In the example of  FIG. 8 , the follower  615  comprises a first magnetic rotor  805 , and the driver  620  comprises a second magnetic rotor  810 . The second magnetic rotor  810  of  FIG. 8  comprises an open cylinder disposed concentrically around the first magnetic rotor  805 . In some embodiments, the first magnetic rotor  805  may comprise first housing  815  and a first plurality of magnets  820  disposed within the first housing  815 . As illustrated in  FIG. 8 , the first housing  815  may have a housing core  825  in some embodiments. In other examples, the first housing  815  may be hollow. In the example of  FIG. 8 , the first plurality of magnets  820  are arranged concentrically around the housing core  825 . The first plurality of magnets  820  may be bonded to the surface of the first housing  815  in some embodiments. The second magnetic rotor  810  may comprise a second housing  830  and a second plurality of magnets  835 . The second plurality of magnets  835  may be supported by the second housing  830  in a cylindrical array concentrically around the first plurality of magnets  820 . A containment seal  840  may be disposed between the follower  615  and the driver  620 . In some embodiments, the first plurality of magnets  820  and the second plurality of magnets  835  are arranged with alternating polarity, as illustrated in the example of  FIG. 8 . 
       FIG. 9  is a section view of the drive module  120  of  FIG. 5 , taken along line  9 - 9  to illustrate additional details that may be associated with some embodiments. As illustrated in the example of  FIG. 9 , the lead nut  610  may be threaded to the lead screw  605 , and the lead sleeve  705  may rigidly couple the follower  615  to the lead nut  610 . For example, the lead sleeve  705  may be bonded to the lead nut  610  in some embodiments. In other examples, the lead nut  610  and the lead sleeve  705  may be integrally molded. The follower  615  may also be bonded to the lead sleeve  705 . As illustrated in the example of  FIG. 9 , the containment seal  840  may fluidly isolate the follower  615  from the driver  620 . For example, the containment seal  840  may comprise or consist essentially of a sleeve or shroud of a liquid-impermeable material disposed between the driver  620  and the follower  615 . In some embodiments, the containment seal  840  may be coupled to the housing  505  to fluidly isolate the driver  620 , the motor  625 , and other components within the housing. The driver  620  may be magnetically coupled to the follower  615  through the containment seal  840 , allowing the follower  615  to freely rotate within the containment seal  840  and the driver  620  to freely rotate around the containment seal  840 . 
     In operation, the follower  615  may be inserted into the containment seal  840  to magnetically couple the follower  615  to the driver  620 . The control switch  515  may be pressed or otherwise activated to operate the motor  625 , which can rotate a motor pin  905 . In some embodiments, the motor pin  905  may be rigidly coupled to an output wheel  910 , which can rotate with the motor pin  905 . Rotation of the output wheel  910  can rotate the drive belt  630 , which can rotate the driver  620 . The magnetic force between the driver  620  and the follower  615  can cause the follower  615  to rotate with the driver  620 , which can rotate the lead sleeve  705  and the lead nut  610 . In some embodiments, the lead screw  605  may have a flat side (see  FIG. 7 ), and some portion of the housing  505  may be configured to engage the flat side of the lead screw  605  to prevent rotation. Preventing rotation of the lead screw  605  allows rotation of the lead nut  610  to advance or retract the lead screw  605  linearly. In the example of  FIG. 9 , the lead screw  605  may be advanced or retracted through the actuator interface  525 . 
       FIGS. 10A-10C  are schematic diagrams illustrating an example method of ejecting an implant  1000  from the system  100 . Initially, various components of the system  100  may be assembled if needed. For example, the nozzle  105 , the implant bay  110 , and the actuator  115  may be coupled to each other as illustrated in  FIG. 10A . The drive module  120  may also be coupled to the actuator  115  through the drive interface  220 . For example, the actuator interface  525  may be configured to align with and be coupled to the drive interface  220  in some embodiments. In some embodiments, the drive shaft  530  may be configured to directly engage the drive seal  230  through the drive interface  220 , as illustrated in  FIG. 10A . In other examples, the drive shaft  530  may be configured to engage the drive seal  230  through the drive interface  220 . 
     The implant  1000  may be provided in the implant bay  110 , as illustrated in the example of  FIG. 10A . In some embodiments, the implant  1000  may comprise an intraocular lens, which may have a shape similar to that of a natural lens of an eye, and it may be made from numerous materials. In the example of  FIG. 10A , the implant  1000  is illustrative of an intraocular lens having an optic body  1005 , a leading haptic  1010 , and a trailing haptic  1015 . Examples of suitable materials may include silicone, acrylic, and combinations of such suitable materials. In some instances, the implant  1000  may comprise an intraocular lens that is fluid-filled, such as a fluid-filled accommodating intraocular lens. 
     In some examples, a working fluid  1020  may be stored in the fluid chamber  235 . In  FIG. 7 , for example, the plunger seal  225  fluidly isolates the bore  215  from the working fluid  1020  in the fluid chamber  235 , which can allow the working fluid  1020  to be stored within the fluid chamber  235  before use. In some examples, the nozzle seal  260  and the first end  250  of the plunger  210  may protrude into the implant bay  110 , as illustrated in  FIG. 10A , which can create a seal in the implant bay  110  behind the implant  1000 . The first end  250  of the plunger  210  may also engage the implant  1000 , in some examples. In other examples, the nozzle seal  260  and the first end  250  may be contained within the housing  205  before use. 
     The plunger  210 , the plunger seal  225 , and the drive seal  230  are generally movable within the housing  205 . For example, in some embodiments, the drive module  120  may move the drive shaft  530  against the drive seal  230 , which can rigidly move the plunger  210 , the plunger seal  225 , the drive seal  230 , and the working fluid  1020 , maintaining a fixed relationship as illustrated in  FIG. 10B . For example, the control switch  515  may be activated to operate the motor  625  to advance the drive shaft  530 , which can move the plunger  210 , the plunger seal  225 , the drive seal  230 , and the working fluid  1020  from the configuration of  FIG. 10A  to the configuration of  FIG. 10B . 
     Movement of the plunger  210  can advance the implant  1000  into a delivery lumen  1025  of the nozzle  105 , which may create a fluid seal between the implant  1000  and the delivery lumen  1025 . In some examples, the implant  1000  may be positioned entirely within the delivery lumen  1025 . In the configuration illustrated in  FIG. 10B , the bypass channel  245  fluidly couples the bore  215  to the fluid chamber  235  around the plunger seal  225 . As the drive shaft  530  and the drive seal  230  apply pressure to the working fluid  1020  in the fluid chamber  235 , the working fluid  1020  may move into the bore  215  through the bypass channel  245 . 
     The plunger  210  may be retained in the position of  FIG. 10B  against further force applied to the drive seal  230 . For example, in some embodiments, the second end  255  of the plunger  210  may be flared, and the plunger interface  240  may be configured to engage the second end  255  to limit advancement. Additionally, or alternatively, the implant bay  110  or the nozzle  105  may comprise a plunger stop  1030  configured to engage some portion or feature of the plunger  210 , such as the second end  255  of the plunger  210 , to prevent further advancement. In yet other examples, some embodiments of the delivery lumen  1025  may be tapered, which can prevent further advancement of the plunger  210  into the delivery lumen  1025 . For example, the diameter of the delivery lumen  1025  may decrease as it gets further from the implant bay  110 . 
     With the plunger  210  retained, additional pressure applied by the drive seal  230  on the working fluid  1020  can move the working fluid  1020  through the bypass channel  245  and the bore  215 , as illustrated in the example of  FIG. 10C . Movement of the working fluid  1020  from the bore  215  into the delivery lumen  1025  under pressure from the drive seal  230  can increase the pressure and flow rate of the working fluid  1020  in the delivery lumen  1025  behind the implant  1000 , which can advance the implant  1000  further through the delivery lumen  1025  until the implant  1000  is ejected. 
       FIGS. 11A-11B  are schematic diagrams further illustrating an example use of the system  100  to deliver the implant  1000  to an eye  1100 . As illustrated, an incision  1105  may be made in the eye  1100  by a surgeon, for example. In some instances, the incision  1105  may be made through the sclera  1110  of the eye  1100 . In other instances, an incision may be formed in the cornea  1115  of the eye  1100 . The incision  1105  may be sized to permit insertion of a portion of the nozzle  105  in order to deliver the implant  1000  into the capsular bag  1120 . For example, in some instances, the size of the incision  1105  may have a length less than about 3000 microns (3 millimeters). In other instances, the incision  1105  may have a length of from about 1000 microns to about 1500 microns, from about 1500 microns to about 2000 microns, from about 2000 microns to about 2500 microns, or from about 2500 microns to about 3000 microns. 
     After the incision  1105  is made, the nozzle  105  can be inserted through the incision  1105  into an interior portion  1125  of the eye  1100 . The system  100  can then eject the implant  1000  through the nozzle  105  into the capsular bag  1120  of the eye  1100 , substantially as described above with reference to  FIGS. 10A-10C . In some applications, the implant  1000  may be delivered with one or more of the leading haptic  1010  and the trailing haptic  1015  in a folded configuration and can revert to an initial, unfolded state, within the capsular bag  1120 , as shown in  FIG. 11B . The capsular bag  1120  can retain the implant  1000  within the eye  1100  in a relationship relative to the eye  1100  so that the optic body  1005  refracts light directed to the retina (not shown). The leading haptic  1010  and the trailing haptic  1015  can engage the capsular bag  1120  to secure the implant  1000  therein. After dispensing the implant  1000  into the capsular bag  1120 , the nozzle  105  may be removed from the eye  1100  through the incision  1105 , and the eye  1100  can be allowed to heal over a period of time. 
     The systems, apparatuses, and methods described herein may provide significant advantages. For example, some embodiments may be particularly advantageous for delivering intraocular lenses, including fluid-filled accommodating lenses, which can present unique challenges for delivery. Some embodiments can compress a relatively large lens to fit through an acceptably small incision, manage deformation caused by shifting fluid during compression and exit from a nozzle, and execute delivery in a predictable and controlled manner. Additionally, some embodiments can reduce system complexity and the number of delivery steps while maintaining haptic position consistency. Some embodiments may also reduce the amount of working fluid for delivery. 
     Additionally, or alternatively, the magnetic coupling between the drive shaft  530  and the driver  620  can allow sealed components within the housing  505  to be removed, which may be advantageous for sterilization and other maintenance, as well as increasing reusability and reducing environmental impacts. For example, steam from autoclaving can present challenges to batteries and other electronics and enclosing these components within the housing  505  and the containment seal  840  can substantially reduce or eliminate some of these challenges by fluidly isolating them from steam during an autoclave cycle. 
     While shown in a few illustrative embodiments, a person having ordinary skill in the art will recognize that the systems, apparatuses, and methods described herein are susceptible to various changes and modifications that fall within the scope of the appended claims. Moreover, descriptions of various alternatives using terms such as “or” do not require mutual exclusivity unless clearly required by the context, and the indefinite articles “a” or “an” do not limit the subject to a single instance unless clearly required by the context. Components may be also be combined or eliminated in various configurations for purposes of sale, manufacture, assembly, or use. For example, in some configurations, the nozzle  105 , the implant bay  110 , the actuator  115 , the drive module  120  may each be separated from one another or combined in various ways for manufacture or sale. 
     The claims may also encompass additional subject matter not specifically recited in detail. For example, certain features, elements, or aspects may be omitted from the claims if not necessary to distinguish the novel and inventive features from what is already known to a person having ordinary skill in the art. Features, elements, and aspects described in the context of some embodiments may also be omitted, combined, or replaced by alternative features serving the same, equivalent, or similar purpose without departing from the scope of the invention defined by the appended claims.
