Abstract:
The nasal catheter system will provide an improvement over existing devices that do not fill the recesses of the nose, do cause significant pain and still do not stop nosebleeds very effectively. The objectives are achieved through the design of a version of the device that has two inflatable bags, which in the preferred embodiment are not elastic balloons. The anterior bag is much larger in volume than the anterior nasal cavity. The design of the bag is generally cylindrical but has deep ridges projecting outward producing a “pleated” design with ribs running along and parallel to the axis of the catheter. Alternate designs include a circumferential ring or capillary tube fingers projecting outward. Any surface projection that serves to create additional surface area or any projection that winds and flows into the meatus recesses of the nasal cavity with greater ease will accomplish some aspect of the desired objective.

Description:
BACKGROUND 
     The field of invention relates to medical devices designed to stop serious nosebleeds. There are many products on the market to stop nosebleeds but none of them work much better than putting some type of gauze packing in the nose. 
     There is a need for a device that will treat the severe nosebleeds or major epistaxsis that is not controlled with gauze slipped into the nose. A device is needed for nosebleeds which are not easily stopped and to replace the one or two inflatable devices, presently available, which are mostly ineffective and tend to be painful. 
     Part of the difficulty with nosebleeds is that the nasal chamber is not a space with flat walls where pressure can be brought to bare. Instead, the nasal cavity has what can be thought of as serpentine deep grooves, called meatus recesses, in the side walls which are fairly narrow and make it difficult to produce pressure in these recessed areas. The present devices will not easily flow into these recesses to stop a nosebleed. A new device is required that will stop nosebleeds, which do not respond to simpler methods. 
     Another problem must be solved when designing a device to stop the more serious nosebleed. The nasal cavity is divided by a center wall, the nasal septum, which produces right and left nasal chamber airways. This center wall extends from the anterior opening of the nose posteriorly, but eventually ends so the posterior part of the nose is just one chamber. The new invention should be capable of entering both the right and left anterior nasal chamber airways or nasal cavities. 
     Therefore, the nasal cavity is made up of two divided chambers anteriorly and a common chamber posteriorly. Nosebleeds can occur either in the anterior or posterior cavities. It is relatively common, especially in older people, to be unable to see where the nosebleed is originating, especially when the treating physician is not an ear, nose and throat (ENT) doctor. When a doctor cannot find the source of bleeding, he/she will commonly call the nosebleed a “posterior nose bleed.” The nosebleed may be in the anterior ⅔&#39;s of the nose or in one of the recesses or in the posterior ⅓ common chamber of the nose but a persistant nosebleed is still commonly called a “posterior epistaxsis”. 
     There is a need for a device that puts more uniform pressure into the nose. Presently used devices use a balloon to “blow up” in the nose but the balloon does not conform to the interior configuration of the nose. The balloon device attempts to fill the nasal interior with an expanding balloon by forcing more water into the balloon, but the balloon does not expand into the serpentine recesses of the nose. These recesses in the lateral wall of the nose are individually called a meatus. Meatus can be both singular and plural when describing more than one meatus. A meatus is created by an “overhang structure” on the side wall of the nose called a turbinate. 
     One of the early methods for treatment is for an “anterior” nose bleed, where gauze is placed into either the right or left side of the nose, whichever is bleeding, or at times both sides of the nose. A “posterior” pack can be placed into the nose in addition to the “anterior” gauze packing. A roll of gauze is inserted into the back of the nose and secured to a second roll of gauze at the opening of the nose with a string so the posterior gauze roll will not fall into the throat. This method is now seldom used since the Foley Catheter method was developed. 
     The Standard Urological Catheter (Foley Catheter) has a balloon that is expanded with water to put pressure in the back of nose, in the common space posterior to the center wall septum. This balloon also allows the physician to insert gauze into the front of the nose with less concern that the packing will fall into the throat and obstruct the airway. The catheter is clamped at the inlet of the nose to keep the balloon from moving backwards into the throat. The balloon of the Foley Catheter produces excessive pressure and pain when inflated in an attempt to fill the posterior cavity of the nose and still does not conform to or fill the entire space. 
     The XOMED™ Epistat™ (XOMED™ and Epistat™ are trademarks of Xomed Surgical Products Inc.) represents the latest technology used to attempt to stop the persistent nosebleed. The XOMED™ Epistat™ uses a catheter traversing through the right or left chamber of the nose. You could put one in each side of the nose. Two balloons are inflated with water. The larger balloon is meant to put pressure in the anterior nasal cavity that is divided into right and left side. The small balloon is meant to put pressure in the posterior chamber of the nose. This is the common chamber. 
     The XOMED™ Epistat™ has inflatable balloons where it is difficult to conform to the shapes of the nasal cavities, especially the anterior cavity. The anterior nasal cavity is the hardest to fill with a balloon. The expanding spherical or ovoid balloon will put minimal pressure in the crevices. Likewise, the posterior nasal cavity is not a sphere and the expanding bulb will not conform to the anatomical space. 
     In an attempt to control the bleeding, the physician will put more and more pressure in the balloons and this causes a significant amount of pain because of the expanding pressure inside the nose. The pain is produced because the balloon is expanded with much more pressure than needed to compress a bleeding vessel. The increased pressure is used to try to drive the balloon into the crevices or serpentine recesses of the nose. These recesses of the nose are the Superior Meatus, Middle Meatus and Inferior Meatus. Regardless of how much pressure is put into the balloon, the balloon will not flow into the crevices of the nose. 
     The XOMED™ Epistat™ balloon expands producing a round or ovoid configuration while producing significant pressure in a very small area, with significant pain, and does not fill much of the interior space of the nose such as the lateral crevices. There is not very effective filling of the posterior nose by the posterior balloon of the XOMED™ Epistat™. The balloon expands in about a sphere and takes on a modified configuration only when significant pressure is used in the balloon and it still does not fill much of the posterior airway, because the balloon does not match the anatomical configuration of the posterior nose. 
     The XOMED™ EPISTAT II™ was believed to have been produced in an attempt to stop bleeding without the need for an anterior nasal balloon. The anterior balloon is the balloon that causes most of the pain. The anterior balloon was replaced with a compressed “sponge” which expands when inserted into the nose. Although the EPISTAT II™ is much less painful, it is not very effective in stopping nosebleeds. The compressed sponge often lacks the force of expansion necessary to place sufficient pressure in the nasal cavities and recesses. There is no external force, such as water from a syringe, that drives the surface of the sponge into the recesses. Only the force of the sponge structure attempting to expand itself is available and this force is most often inadequate. 
     The present state of technology in medical devices for stopping serious nosebleeds is inadequate since the current devices lack the ability to effectively flow into the recesses of the anterior nasal cavity or fill the posterior nasal cavity and use severe pressure with associated intense pain. Therefore, a need exists for a new medical device that will overcome these deficiencies. 
     SUMMARY OF THE INVENTION 
     The present invention will effectively flow into the recesses of the nasal cavity without severe pressure and the associated intense pain thus filling the anterior nasal cavity, meatus and posterior nose without causing significant discomfort. The present invention will provide an improvement over existing devices that do not fill the recesses of the nose, do cause significant pain and still do not stop nosebleeds very effectively. 
     The objectives are achieved through the design of a nasal catheter system to stop a nosebleed coming from one or both of the nasal airways, either right and/or left nasal airways. A version of the device has two inflatable bags, which in the preferred embodiment are not elastic balloons. The anterior bag is much larger in volume than the anterior nasal cavity. The design of the bag is generally cylindrical but has deep ridges projecting outward producing a “pleated” design with ribs running along and parallel to axis of the catheter. Alternate designs include a circumferential ring or capillary tube fingers projecting outward. Any surface projection that serves to create additional surface area or any projection that winds and flows into the recesses with greater ease will accomplish some aspect of the desired objective. 
     Traditional devices typically are spherical or ovoid shaped balloons that lack the added surface projections to flow and wiggle into the deep crevices without extreme pressure and associated severe pain to the patient. The shape and redundancy of size of the present invention will allow the anterior bag and surface projections to fill the anterior chamber and “flow” into the deep crevices of the nose without the need for excessive pressure and pain. The addition of surface projections to the anterior bag creates a significantly improved flow capability over the traditional spherical or ovoid shaped devices. 
     The anterior and posterior bags are twisted around the catheter to allow easy insertion into the nose. The posterior bag is constructed to the shape of the posterior nose and is slightly larger than the volume of the posterior nose. However, the posterior bag is not as redundantly oversized as the anterior bag. The posterior bag is not as redundant so that the bag will not extend or drop down into the throat. The anterior bag, which is more oversized, will actually flow into proximal anterior extent of the posterior nasal cavity to fill any space not occupied by the posterior bag. 
     The anterior and posterior bags will inflate with water or other fluid to a predetermined size and configuration. The posterior bag is not an elastic balloon, in the preferred embodiment. The anterior and posterior bags are made of medical grade silicone in the preferred embodiment. 
     A two channel catheter protrudes from the nostril to allow the instillation of water into each bag separately. The ends of the two channels protruding from the nose will be gradually flared to a diameter which fits over a standard hospital syringe used for irrigation or administering medication. The ends of the two channels will not have the bulky injection ports as in the XOMED™ Epistat™. 
     The existing XOMED™ Epistat™ has two injection ports each containing a valve which allows insertion or removal of water from the catheter. The preferred embodiment differs from the XOMED™ Epistat™, with a catheter which contains two lumens so water can be inserted individually into the anterior and posterior bags but does not have any valves. The two lumens are separated into two channels at the inlet of the nose to allow individual filling and clamping. After the device is inserted into the nose, a soft silicone nasal plug will be “snugged” into the nostril after the common catheter has been brought out through the central channel. 
     The posterior bag will be inflated with water while pulling on the catheter so the posterior bag does not fall down in the throat. Once the posterior balloon is inflated, the channel to the posterior balloon is closed with a small medical clamp as the channel exits the nasal plug. The nasal plug is kept in place and the anterior bag is inflated with water with some “to and fro” and twisting motion of the catheter to allow the redundant anterior bag to flow into the crevices. The nasal plug is kept in place as the anterior bag is filled so that the redundant anterior bag does not extrude out the nostril. 
     When the anterior bag is filled and the epistaxsis nosebleed is controlled, a slightly larger clamp is placed on the common catheter as both channels exit from the nasal plug. This clamp and nasal plug keeps the entire catheter/bag system from falling into the throat. Since the posterior bag will be larger in diameter than the anterior nasal airway, the posterior bag keeps the catheter/bag system from extruding out the nostril. 
     One embodiment of the inventive concept consists of one catheter with two anterior bags and one posterior bag. One of the anterior bags fills the right anterior nose and the other anterior bag fills the left anterior nose. The single posterior bag is designed to completely fill the posterior chamber. All bags can be filled individually through a double channel catheter which exits both nostrils. The catheter enters both the right and left airways. It has an anterior bag for both right and left anterior nasal cavities and one posterior bag for the common posterior nasal cavity. The catheter goes around the posterior septum and is secured anteriorly at the nostril with a nasal plug and clamp at both nostrils. 
     The individual fluid channels to the anterior and posterior bags are filled individually, clamped individually and then both clamped by a single clamp around the common catheter as it exits the nasal plug to produce a completed intra nasal pressure device. The redundancy of size and ridge projections will flow into all areas. 
     When the bags are filled with water, the entire system is “snugged” with firmness by pulling on the combined dual common catheter while pressing inward on the nasal plug and clamping the dual common catheter with one clamp. The least complex version has one anterior bag, this device would be more effective and more convenient than other devices now available to stop the milder anterior nosebleeds. 
     The nasal catheter system includes; a catheter having a first anterior fluid channel, a first anterior output opening, a first anterior input port, and a first external section. There is a first anterior bag fixedly attached to the catheter. The first anterior bag has a first anterior chamber, a first outer surface, a first front end, a first middle portion and a first rear end. There is a plurality of first anterior elongated ridges attached to the first outer surface and spanning over about the first middle portion, the plurality of first anterior elongated ridges have a plurality of first anterior ridge cavities. The first anterior ridge cavities are in communication with and connected to the first anterior chamber. The nasal catheter system is inserted into a first anterior nasal cavity and then the catheter is filled with a fluid that flows through the first anterior fluid channel and into the first anterior bag, thereby expanding the first anterior bag and producing pressure upon the first anterior nasal cavity. 
     The nasal catheter system can additionally include a posterior fluid channel that has a posterior section, a first posterior input port and a posterior output opening. Attached to the catheter is a posterior bag with a posterior chamber. The nasal catheter system is inserted into the first anterior nasal cavity and a posterior nasal cavity so that when the posterior fluid channel is filled with a fluid, the fluid flows through the posterior fluid channel and into the posterior bag, thereby expanding the posterior bag and producing pressure upon the posterior nasal cavity. 
     The nasal catheter system can also be expanded to include a second anterior bag attached to a second anterior fluid channel having a second anterior output opening, a second anterior input port and a second external section. The second anterior bag has a second anterior chamber, a second outer surface, a second front end, a second middle portion and a second rear end. There is a plurality of second anterior elongated ridges attached to the second outer surface and spanning over about the second middle portion. The plurality of second anterior elongated ridges have a plurality of second anterior ridge cavities that are in communication with and connected to the second anterior chamber. The nasal catheter system may be additionally inserted into a second anterior nasal cavity and when the catheter is filled with a fluid, the fluid flows through the second anterior fluid channel and into the second anterior bag, thereby expanding the second anterior bag and producing pressure upon the second anterior nasal cavity. 
     The nasal catheter system can have an elongated section removably attached to the first external section or the second external section of the catheter. The elongated section may be inserted through the first anterior nasal cavity, the posterior nasal cavity and into the throat. Then a secondary member can be inserted through the second anterior nasal cavity, the posterior nasal cavity and into the throat. The secondary member is then attached to the elongated section of the catheter. Next the secondary member is pulled back through the second anterior nasal cavity, pulling the catheter, the posterior bag, the first anterior bag and the second anterior bag into the posterior nasal cavity, first anterior nasal cavity and second anterior nasal cavity. 
     A second posterior input port can be added to the posterior fluid channel. This allows filling of the posterior bag from either the first or second posterior input port. The first anterior bag, second anterior bag and posterior bag are made of silicone in one embodiment. 
     The surface projections may be arranged in a variety of configurations, including where the plurality of first anterior elongated ridges span from about the first front end to about the first rear end including the first middle portion and the plurality of second anterior elongated ridge span from about the second front end to about the second rear end including the second middle portion. 
     Another version has the first anterior bag with a first anterior chamber, a first long axis with a plurality of first anterior circumferencial ridges attached to a first outer surface and axially positioned in circumferencial rings about the first long axis. The plurality of first anterior circumferencial ridges span over about the first middle portion. The plurality of first anterior circumferencial ridges have a plurality of first anterior circumferencial ridge cavities. The first anterior circumferencial ridge cavities are in communication with the first anterior chamber. 
     The second anterior bag would have a similar arrangement with a second anterior chamber, a second long axis, a second outer surface, a second front end, a second middle portion and a second rear end. A plurality of second anterior circumferencial ridges are attached to the second outer surface and axially positioned in circumferencial rings about the second long axis. The plurality of second anterior circumferencial ridges span over about the second middle portion, the plurality of second anterior circumferencial ridges having a plurality of second anterior circumferencial ridge cavities that are in communication with the second anterior chamber. 
     Another version of the surface projections from the first anterior bag is a plurality of first anterior capillary tubes with a first open end and a first closed end. The plurality of first anterior capillary tubes are attached to the first outer surface and take the form of finger-like projections extending generally perpendicular from the first outer surface and spanning over about the first middle portion. The plurality of first anterior capillary tubes have a plurality of first anterior capillary tube cavities. The first open end of the first anterior capillary tube cavities are in communication with the first anterior chamber. 
     In a similar arrangement the second anterior bag can have a plurality of second anterior capillary tubes. The second anterior bag has a second anterior chamber, a second outer surface, a second front end, a second middle portion and a second rear end. The plurality of second anterior capillary tubes have a second open end, a second closed end and are attached to the second outer surface. The plurality of second anterior capillary tubes take the form of finger-like projections extending generally perpendicular from the second outer surface and spanning over about the second middle portion, the plurality of second anterior capillary tubes having a plurality of second anterior capillary tube cavities where the second open end of the second anterior capillary tube cavities are in communication with the second anterior chamber. 
     Another alternative arrangement of the nasal catheter system is where the plurality of first anterior capillary tubes span from about the first front end to about the first rear end including the first middle portion and the plurality of second anterior capillary tubes span from about the second front end to about the second rear end including the second middle portion.

     DESCRIPTION 
     Referring to FIGS. 1-16, A nasal catheter system  10  includes a catheter  12  having a first anterior fluid channel  14 , a first anterior output opening  16 , a first anterior input port  18 , and a first external section  20 . The first anterior bag  22  is securely attached to the catheter  12 . This simplest version with one first anterior bag  22  is illustrated in FIG.  14 . The nasal catheter system  10  can be more complex and have a second anterior bag  24  and a posterior bag  26  attached to the catheter  12  as shown in FIGS. 1,  2   a ,  2   b.    
     The nasal catheter system  10  is inserted into a first anterior nasal cavity  32  and when the catheter  10  is filled with a fluid  30  via the first anterior input port  18 , the fluid  30  flows through the first anterior fluid channel  14  and into the first anterior bag  22 , thereby expanding the first anterior bag  22  and producing pressure upon the first anterior nasal cavity  32 . The first anterior fluid channel  14  ends at about the first anterior output opening  16 . 
     When included a second anterior bag  24  is inserted into the second anterior nasal cavity  34  and the first anterior bag  22  is inserted into a first anterior nasal cavity  32 , as shown on FIGS. 4,  5 . The posterior bag  26  is inserted into the posterior nasal cavity  36  that is behind the first and second anterior nasal cavity  32 ,  34 . 
     The first anterior bag  22  has a first anterior chamber  40 , a first outer surface  42 , a first front end  44 , a first middle portion  46  and a first rear end  48 . A plurality of first anterior elongated ridges  50  are attached to the first outer surface  42  and span over about the first middle portion  46 . The plurality of first anterior elongated ridges  50  have a plurality of first anterior ridge cavities  52 . The first anterior ridge cavities  52  are connected to and in communication with the first anterior chamber  40 . 
     The preferred fluid  30  is water  54 . When water  54  is injected into the first anterior fluid channel  14  it passed through the first anterior output opening  16  into the first anterior ridge cavities  52  and the first anterior chamber  40 . The water  54  creates pressure upon the first anterior ridge cavities  52  and the first anterior chamber  40  causing them to expand and producing pressure upon the first anterior nasal cavity  32 . 
     When the posterior bag  26  is included then the catheter  10  has a posterior fluid channel  58  that has a posterior section  60 , a first posterior input port  62  and a posterior output opening  66 . A second posterior input port  64  can be added, in which case, the posterior fluid channel  58  would be extended and the second posterior input port  64  attached to the posterior fluid channel  58 . Both the first posterior input port  62  and second posterior input  64  port provide fluid  30  or water  54  to the posterior output opening  66 . Either the first posterior input port  62  or second posterior input port  64  can be used for convenience. 
     The posterior bag  26  is attached to the catheter  10  near the posterior output opening  66 . The posterior bag  26  is filled when water  54  or fluid  30  is inserted into the first posterior input port  62  or the second posterior input port  64  and the water  54  flows though the posterior fluid channel  58  and through the posterior output opening  66  into the posterior bag  26 . The posterior fluid channel  58  generally parallels and adjoins the first anterior fluid channel  14  and the second anterior fluid channel  74 . The posterior bag  26  has a posterior chamber  70  that fills with water  54  and expands the posterior bag  26  and produces pressure upon the posterior nasal cavity  36 . 
     In some patients the physician cannot ascertain from which anterior nasal cavity  32 ,  34  the bleeding is occurring. The solution is to provide a second anterior bag  24  attached to the catheter  12 . Filling of the second anterior bag  24  is accomplished by adding to the catheter  12 ; a second anterior fluid channel  74  having a second anterior output opening  76 , a second anterior input port  78 , and a second external section  80 . 
     Referring particularly to FIGS. 2 a ,  2   b ; the second anterior bag  24  is attached to the second anterior fluid channel  74 , the second anterior bag has a second anterior chamber  82 , a second outer surface  84 , a second front end  86 , a second middle portion  88  and a second rear end  90 . Attached to the second outer surface  84  are a plurality of second anterior elongated ridges  92  that span over about the second middle portion  88 . The plurality of second anterior elongated ridges  92  have a plurality of second anterior ridge cavities  94 . The second anterior ridge cavities  94  are connected to and are in communication with the second anterior chamber  82 . FIG. 1 c  and FIG. 14 c  show the nasal catheter system  10  being coiled or wrapped for insertion. 
     The second anterior bag  24  may be inserted into a second anterior nasal cavity  34  and when the catheter  12  is filled with a fluid  30 , the fluid  30  flows through the second anterior fluid channel  74  and into the second anterior bag  24 , which expands the second anterior bag  24  and producing pressure upon the second anterior nasal cavity  32 . 
     Referring to FIG. 2 b , to secure the nasal catheter system  10  within the nasal cavity  28  a nasal plug  95  is used to receive the first external section  20  and a second nasal plug  95 ′ secures the second external section  80 . The first external section  20  can then be clamped by a clamping device  97  and the second external section  80  is secured by clamping device  97 ′, thus securing the nasal catheter system  10  within the nasal cavity  28 . 
     Pressure is placed upon the meatus recesses  96  of the nasal cavity  28  when the nasal catheter system  10  is inserted into a nasal cavity  28  and a fluid  30  is inserted into the first anterior input port  18  of the catheter  12 , and the fluid  30  passes through the catheter  12  and passes through the first anterior output opening  16  into the first anterior bag  22 . This expands the first anterior chamber  22  and the plurality of first anterior ridge cavities  52 . The expansion causes the plurality of first anterior ridge cavities  52  to press against the interior walls of the nasal cavity  28  and flow into additional open spaces of the meatus recesses  96 . Since the first anterior ridge cavities  52  will search for a path of least resistance, the first anterior ridge cavities  52  will wind and flow into the meatus recesses  96  thereby producing pressure upon the nasal cavity  28  and meatus recesses  96  that is much more effective and less painful than conventional methods. 
     FIG. 5 a ,  10   a  illustrates the meatus recesses  96 . They are the superior meatus  142 , middle meatus  144  and inferior meatus  146 . The meatus recesses  142 , 144 , 146  are deep and winding recesses that are not easily accessed by traditional round or ovoid inflatable balloons  104 . 
     Referring to FIG.  3  and FIG. 4, the insertion of the three-bag embodiment into the nose  116  requires more than just pushing it into either or both nostrils  106 ,  107 . When the second anterior bag  24  is included it is necessary to pull the first anterior bag  22  and catheter  12  through the second anterior nasal cavity  34 , the posterior nasal cavity  36  and into the throat  38  in order to reach the first anterior nasal cavity  32 . The catheter system  10  must be inserted into the second nostril  107  on one side of the nose  116  and advanced into the posterior nasal cavity  36  and then brought into the opposite first posterior nasal airway  112  and out through the first anterior nasal cavity  32  and first nostril  106 . To accomplish this the leading end, external section, of the device&#39;s catheter  12  is elongated by eighteen to twenty-four inches which allows the insertion of the elongated section  108  of the catheter  12  into the second nostril  107 . The elongated section  108  is brought out the mouth by advancing the catheter  12  through the nose  116  until it can be visualized looking through the mouth  110  into the throat  38  and grasped with a hemostat  162  to pull it from the throat  38  and out of the mouth  110 . 
     Although the maneuver as depicted on FIG. 3 puts the catheter system  10  into the second nostril  107  and brings it out the mouth  110 , it does not result in the catheter  12  being brought out the other first posterior nasal airway  112 . To do this a second and separate tube depicted as secondary member  114  needs to be inserted into the opposite first nostril  106  and advanced into the back of the throat  38  and pulled from the throat  38  and out the mouth  110 . This secondary member  114  does not have any inflatable bag. The secondary member  114  can be a second catheter. Its only purpose is to attach to the elongated portion  108  of the catheter  12  and pull the catheter system  10  from the back of the throat  38  into the first posterior nasal airway  112  of the opposite side of the nose  116  and out through the first anterior nasal cavity  32  and first nostril  106 . 
     FIG. 4 illustrates how the secondary member  114  is inserted into the second nostril  107 , is brought through the mouth  110  and attaches to the elongated section  108  of the catheter  12  with a small circular clamp device  97 ′. A circular clamp device  97 ′ or other commonly used clamping medical device can be used to attach the secondary member  114  to the elongated portion  108  of the catheter  12 . The catheter  12  is then pulled into the nose  116  by pulling the secondary member  114  which pulls the catheter  12  into the second nostril  107 , then to the back of the nose  116  and then forward into the opposite first anterior nasal cavity  32  and out through the opposite first nostril  106 . The elongated section  108  is discarded by cutting the catheter  12  as it exits from the first nostril  106  of the nose  116 . The three bags  22 ,  24 ,  26  are inflated with water  54  and secured at the nostrils  106 ,  107  by clamping the common catheter  12  over the nasal plugs  95 . 
     The catheter  12  is depicted with an elongated section  108  where the secondary member  114  is used to pull the nasal catheter system  10  through the nasal cavity  28  when a second anterior bag  24  is used. In a variation the secondary member  114  can be attached directly to a lengthened first external section  20  or second external section  80  of the catheter  12 , depending on the design. The secondary member  114  is cut and discarded once the procedure is complete. 
     The catheter  12  is inserted through the second anterior nasal cavity  34 , the posterior nasal cavity  36  and into the throat  38  where the secondary member  114  is then attached. The secondary member  114  may be inserted through the first anterior nasal cavity  32 , the posterior nasal cavity and into the throat  38 . The secondary member  114  is then attached to the elongated section  108  of the catheter  12 . The secondary member  114  is pulled back through the first anterior nasal cavity  32 , pulling the catheter  12 , the posterior bag  26 , the first anterior bag  22  and the second anterior bag  24  into the posterior nasal cavity  36 , first anterior nasal cavity  32 , and second anterior nasal cavity  34 . 
     Although not illustrated, rather than using the three bag nasal catheter system  10  that requires pulling portions of the nasal catheter system  10  through the throat  38 ; an alternative is to use an embodiment where two nasal catheter system  10  are used that consist of a catheter  12  with a first anterior bag  22  and a posterior bag  26 , with a second nasal catheter system  10  consisting of just a second anterior bag  24  and separate catheter  12 . The two systems  10  are not connected so they can be inserted separately into the first anterior nasal cavity  32  and the second anterior nasal cavity  34 . 
     This alleviates the need to pull the first anterior bag  22  all the way through the second anterior nasal cavity  34  and the posterior cavity  36 , in order to reach the first anterior nasal cavity  32 . The advantage of the three bag nasal catheter system  10  is that once inserted into the nasal cavity  28  the posterior bag  26 , the first anterior bag  22  and the second anterior bag  24  are all connected and serve to hold each other firmly and securely into proper position. 
     The nasal catheter system  10  can be constructed of various materials. Materials commonly used in the medical industry for catheter  12  are acceptable. In the preferred embodiment the first anterior bag  22 , second anterior bag  24  and posterior bag are made of medical grade silicone with the appropriate expandability for accessing the meatus recesses  96  and providing adequate pressure to stop the nose bleed. 
     Referring to FIGS. 1 b ,  2   b ; surface projections attach to the first and second anterior bag  22 ,  24 . The surface projections may vary in configuration. An effective design of the surface projections is with a plurality of first anterior elongated ridges  50  and second anterior elongated ridges  92  that are capable of effectively accessing the meatus recesses  96  without creating painful pressure within the nasal cavity  28 . The plurality of first anterior elongated ridges  50  span from about the first front end  44  to about the first rear end  48  including the first middle portion  46  of the first anterior bag  22 . The plurality of second anterior elongated ridges  92  span from about the second front end  86  to about the second rear end  90  including the second middle portion  88  of the second anterior bag  24 . 
     When the catheter  12  is filled with a fluid  30 , the fluid  30  flows through the first anterior fluid channel  14  and into the first anterior bag  22 , thereby expanding the first anterior bag  22  and first anterior elongated ridge cavities  52  producing pressure upon the first anterior nasal cavity  32 . 
     The plurality of first anterior elongated ridges  50  shown in FIGS. 1 b ,  2   b  and second anterior elongated ridges  92  may vary in placement quantity, circumference, shape, length and other characteristics. Other variations of the surface projections include circumferencial ridges  118 ,  122  shown in FIG. 15 a-c  and capillary tubes  128 ,  138  shown in FIG. 16 a-c  that also may vary in placement quantity, circumference, shape, length and other characteristics. 
     FIG. 15 a ,  15   b  illustrates the plurality of first anterior circumferencial ridge  118  attached to the first outer surface  42  and axially positioned in circumferencial rings about the first long axis  126  and spanning over about the first middle portion  46 . The plurality of first anterior circumferencial ridge  118  have a plurality of first anterior circumferencial ridge cavities  120 . The first anterior circumferencial ridge cavities  120  are in communication with the first anterior chamber  40 . 
     In a similar arrangement, the second anterior bag  24  includes a plurality of second anterior circumferencial ridges  122  attached to the second outer surface  84  and axially positioned in circumferencial rings about the second long axis  127 . The plurality of second anterior circumferencial ridges  122  span over about the second middle portion  89 . FIG. 15 c  shows the plurality of second anterior circumferencial ridges  122  having a plurality of second anterior circumferencial ridge cavities  124 , the second anterior circumferencial ridge cavities  124  are in communication with the second anterior chamber  82 . The first anterior circumferencial ridges  118  and second anterior circumferencial ridges  122  are similar in most all characteristics and function, other than which anterior bag  22 ,  24  they are associated with. 
     FIGS. 16 a ,  16   b ,  16   c  show another variation of the surface projections is a plurality of first anterior capillary tubes  128 . The first anterior bag  22  includes a plurality of first anterior capillary tubes  128  attached to the first outer surface  42  having a first open end  132  and a first closed end  134  and attached to the first outer surface  42 . The first anterior capillary tubes  128  take the form of finger-like projections extending generally perpendicular from the first outer surface  42  and spanning over about the first middle portion  46 . The plurality of first anterior capillary tubes  128  having a plurality of first anterior capillary tube cavities  130 . The first open end  132  of the first anterior capillary tube cavities  130  are in communication with the first anterior chamber  40 . 
     As shown in FIG. 16 c ; in a similar arrangement, the second anterior bag  24  includes a plurality of second anterior capillary tubes  138  attached to the second outer surface  84 . The plurality of second anterior capillary tubes  138  have a plurality of second anterior capillary tube cavities  140  that are in communication with the second anterior chamber  82 . The first anterior capillary tubes  128  and second anterior capillary tubes  138  are similar in most all characteristics and function, other than which anterior bag  22 ,  24  they are associated with. 
     FIG. 16 a  shows the plurality of first anterior capillary tubes  128  spanning from about the first front end  44  to about the first rear end  48  including the first middle portion  46 . The plurality of second anterior capillary tubes  138  span from about the second front end  86  to about the second rear end  90  including the second middle portion  88 . 
     Parts of the nasal catheter system  10  can be manufactured from medical grade silicone, rubber or any other sufficiently expandable materials that are safe for usage internally within the patient. 
     FIG. 5 a  shows the difficult to access crevices of the nasal cavity  28 . These crevices are the Superior Meatus  142 , Middle Meatus  144  and Inferior Meatus  146 , which are separated by the Superior Turbinate  148 , Middle Turbinate  150  and Inferior Turbinate  152 . The nasal septum  154  separates the first anterior nasal cavity  32  from the second anterior nasal cavity  32 . FIG. 5 b  shows the first anterior nasal cavity  32  and posterior nasal cavity  36 . 
     FIGS. 7 a ,  7   b ,  7   c  illustrates the prior art method of gauze  156  being placed into the nose. FIGS. 7 a  and  7   b  show the anterior gauze  156  is packed into the anterior nasal cavity  32 ,  34 . FIG. 7 c  shows one of the early methods for treatment for an “anterior” nose bleed, where gauze is placed into either the right or left side of the nose, whichever is bleeding or at times both sides of the nose. A “posterior” gauze pack  158  is placed into the nose  116  in addition to the “anterior” gauze packing  156 . A roll of gauze is inserted into the back of the nose and secured to a second roll of gauze at the opening of the nose  116  with a string  160  so the posterior gauze roll  158  will not fall into the throat. This method is now seldom used since the Foley Catheter method was developed. 
     FIG. 8 shows the Standard Urological Catheter (Foley Catheter) with a balloon  104  that is expanded with water  54  to put pressure in the back of nose, in the common space posterior nasal cavity  36  to the center wall (septum). This balloon  104  also allows the physician to insert gauze into the front of the nose  116  with less concern that the packing will “fall” into the throat  38  and obstruct the airway. The catheter  12  is clamped at the inlet of the nose to keep the balloon  104  from moving backwards into the throat  38 . The balloon  104  of the Foley Catheter produces excessive pressure and pain when inflated in an attempt to fill the posterior nasal cavity  36 . 
     FIG. 9 shows the Xomed™ Epistat™, which represents the latest technology used to attempt to stop the persistent nosebleed. The Xomed™ Epistat™ uses a catheter  12  traversing through the right or left chamber of the nose. You could put one in each side of the nose. Two balloons  104 ,  105  are inflated with water. The larger balloon  104  is meant to put pressure in the anterior nasal cavity which is divided into right and left side. The small balloon  105  is meant to put pressure in the posterior nasal cavity  36  of the nose  116 , this is the common chamber. 
     As shown in FIG. 10 a  and FIG. 11 a  the Xomed™ Epistat™ has inflatable balloons  104 ,  105  which can never conform to the shapes of the nasal cavities  28 , especially the anterior nasal cavity  32 ,  34 . The anterior nasal cavity  32 ,  34  is the hardest to fill with a balloon  104 . The expanding spherical or ovoid balloon  104  will put minimal pressure in the crevices of the meatus recesses  96 . Likewise, the posterior nasal cavity  36  is not a sphere and the expanding bulb will not conform to the anatomical space. 
     In an attempt to control the bleeding, the physician will put more and more pressure in the balloons  104 ,  105  and this causes a significant amount of pain because of the expanding pressure inside the nose  116 . The pain is produced because the balloon  104  is expanded with much more pressure than needed to compress a bleeding vessel. The increased pressure is used to try to “drive” the balloon into the crevices or “serpentine meatus recesses”  96  of the nose  116 . Regardless of how much pressure is put into the balloon, the balloon will not “flow” into the crevices of the nose. 
     FIGS. 10 a  and  11   a  show how the Xomed™ Epistat™ balloon  104  expands producing a round or ovoid configuration while producing significant pressure in a very small area, with significant pain, and not filling any of the major area of the nose such as the Superior Meatus  142 , Middle Meatus  144  and Inferior Meatus  146  crevices. There is ineffective filling of the posterior nasal cavity  36  by the posterior balloon of the Xomed™ Epistat™. The balloon can only expand in a sphere and takes on a modified configuration only with significant pressure in the balloon and still does not fill the posterior nasal cavity  36 . 
     FIGS. 10 b  and  11   b  show complete filling of the Superior Meatus  142 , Middle Meatus  144  and Inferior Meatus  146  by the second anterior bag  24  of the present invention. The posterior bag  26  is designed to the shape of the anatomical space in the posterior cavity  36 . It is slightly larger than this space to effect pressure in all areas and completely fills the posterior nasal cavity  36 . 
     FIG. 12 a ,  12   b ,  13   a  and  13   b  show the catheter  10  with the first anterior fluid channel  14  to the first anterior bag  22  and posterior fluid channel  58  to the posterior bag  26  that allows them to be filled individually, clamped individually and then both clamped by a single clamp  97  around the common catheter  12  as it exits the nasal plug  95  to produce a completed intra nasal catheter system  10 . 
     FIG. 12 b  shows the posterior bag  26  filed with water  54  and the posterior fluid channel  58  to the posterior bag  26  individually clamped. FIG. 13 a  show both the posterior bag  26  and first anterior bag  22  filled with water  54 . The posterior fluid channel  58  and anterior fluid channel  14  are then individually sealed with clamps  97 ,  97 ′. The redundancy of size and ridge projections will flow into all areas 
     FIG. 13 b  illustrates both bags  26 ,  22  filled with water and the entire system “snugged” with firmness by pulling on the combined dual common catheter  10  while pressing inward on the nasal plug  95  and clamping the dual common catheter  10  with one clamp  97 . 
     Filling the variation with three bags  22 ,  24 ,  26  would be carried out in a similar manner once the nasal catheter system  10  was in place inside the nose  116 . The posterior bag  26  would be filled from the left nostril through the first posterior input port  62  while the second posterior input port  64  to the posterior bag  26  is individually clamped. The first and second anterior bags  22 ,  24  would then be filled and individually clamped. A common clamp  97  would then be applied to the common catheter  10  coming out each nostril and through the nasal plug  95 . 
     The least complex version has one first anterior bag  22 , this device would be more effective and more convenient than other devices now available to stop the milder anterior nosebleeds.
