Definitions

  • the present invention relates generally to medical device assemblies and relates more particularly to a novel such medical device assembly.
  • the present invention also relates to a protective sheath assembly for use with medical devices.
  • Certain patients are unable to take food and/or medications transorally due to an inability to swallow. Such an inability to swallow may be due to a variety of reasons, such as esophageal cancer, neurological impairment and the like.
  • the intravenous administration of food and/or medications to such patients may be a viable short-term approach, it is not well-suited for the long-term. Accordingly, the most common approach to the long-term feeding of such patients involves gastrostomy, i.e., the creation of a feeding tract or stoma between the stomach and the upper abdominal wall.
  • Feeding is then typically performed by administering food through a catheter or feeding tube that has been inserted into the feeding tract, with one end of the feeding tube extending into the stomach and being retained therein by an internal anchor or bolster and the other end of the feeding tube extending through the abdominal wall and terminating outside the patient.
  • one end of an endoscope is intubated (i.e., inserted) into a patient's mouth and is passed through the esophagus into the stomach.
  • an entry site on the abdomen is identified using the endoscope for transillumination, and an incision is made by passing the tip of a needle coupled to an outer cannula through the abdominal and stomach walls and into the stomach.
  • One end of the outer cannula remains outside of the body and acts as a stop to limit insertion of the needle and outer cannula into the stomach.
  • a snare is inserted into the stomach via the endoscope and is looped over the inserted end of the needle.
  • the snare is then "walked” up the needle until the outer cannula is snared.
  • the snared cannula is then pulled externally to tack the cannula to the stomach and, in turn, to secure the stomach wall to the abdominal wall.
  • the needle is then removed from the patient while keeping the cannula in place.
  • a looped first end of a suture (also known in the art as a "pullwire”) is inserted through the cannula and into the stomach where it is grasped by the snare, the second end of the suture remaining external to the patient.
  • the endoscope and the snare are then withdrawn from the mouth of the patient to deliver the first end of the suture.
  • the pull-type catheter implanting assembly is then pulled retrograde through the patient until the gastrostomy feeding tube emerges from the abdomen of the patient and the internal bolster engages the stomach wall of the patient.
  • the clinician re-intubates the patient with the endoscope in orderto visually inspect the placement of the internal bolster within the stomach. If the internal bolster is properly placed against the stomach wall, a length of the externally-extending portion of the implanted gastrostomy feeding tube is then typically cut and removed from the implanted tube to reduce the externally-extending portion of the tube to a desired length (typically about 4-6 inches).
  • a "Y-port" adapter is typically attached to the external end of the feeding tube, the Y-port adapter being adapted to receive a pair of connector tips through which food and/or medications may be dispensed.
  • a detachable locking clip is typically secured to the implanted feeding tube at a point between the external bolster and the Y-port adapterto prevent gastricfluids from escaping through the proximal end of the feeding tube when the feeding tube is not in use.
  • the pull method involves drawing the PEG device through the alimentary tract of the patient and then out through the wound until the internal bolster of the PEG device engages the stomach wall of the patient in the area surrounding the wound site.
  • the PEG device passes through the patient en route to its final destination, the PEG device is exposed to many types of bacteria, fungi, viruses, and other biological materials that are present within the patient.
  • translocation to another area of the patient may be harmful to the patient.
  • the translocation of certain types of bacteria from the mouth, pharynx, esophagus or stomach to the wound site or to the peritoneal cavity can result in a bacterial infection in the patient that can rapidly spread.
  • Such infections can be quite serious, even fatal, especially if they are not treated properly.
  • This problem of bacterial infection is common in those parts of the world where antibiotic availability and/or use is limited.
  • Another harmful example of translocation is the translocation of cancer cells from the alimentary tract to the wound site or to the peritoneal cavity. The seriousness of this problem is exacerbated by the fact that many patients undergoing the implantation of a PEG device suffer from cancer of the pharynx, esophagus or the like.

  • Internal bolster 19, which also may be made of a soft, biocompatible, silicone rubber, may be securely disposed at trailing end 25 of tube 17 and, in the present embodiment, may form a unitary structure therewith.
  • a series of ruler markings (not shown) may be printed on tube 17 and may extend several inches from trailing end 25 in the direction of leading end 27 to facilitate the cutting of tube 17, after it has been implanted in a patient, to a desired length.

  • Fitting 29 which may be made of a rigid plastic, may be shaped to include a barbed rear portion 31 mounted within leading end 27 of tube 17 and a conical front portion 33 that serves as a dilator, front portion 33 tapering in diameter from a point proximate to leading end 27 of tube 17 to a front tip 35.
  • a wire loop 37 which may be secured to the first end of a suture, may be fixed (typically by insert-molding) to front tip 35.

Such weakened areas 53 may be designed to tear when bolster 19 is pulled thereagainst, thereby permitting bolster 19 to pass easily through distal end 47.
  • Lumen 49 may be dimensioned to be sufficiently long to receive substantially the entire length of subassembly 15, except for loop 37 (which preferably is not received within lumen 49, but rather, may extend distally through aperture 51 so that loop 37 may easily be tied to a suture).
  • Sheath 41 may be made of a material that is sufficiently flexible to permit tube 17, which is disposed therewithin, to bend freely. Accordingly, sheath 41 may be thin walled, for example, having a wall thickness up to about 0.007 inches. In addition, sheath 41 may be sufficiently non-permeable to keep germs and other biological matter from passing therethrough to tube 17. Moreover, sheath 41 may be made of a hydrophilic material and may be transparent or translucent. Examples of materials suitable for use as sheath 41 include non-permeable, medical grade polyethylenes and polyurethanes. If desired, an antimicrobial coating and/or a lubricious coating may be on sheath 41 or applied to sheath 41.

Un ensemble de dispositif médical comprend une gaine de protection. Dans une mode de réalisation, l'ensemble comprend un sous-ensemble d'implantation du cathéter de type à retrait et un sous-ensemble de gaine de protection. Le sous-ensemble d'implantation du cathéter comprend un tube d'alimentation à gastrotomie possédant une extrémité avant et une extrémité arrière. Un renfort interne est disposé à l'extrémité arrière du tube, et un raccord, qui possède un bord avant qui sert comme un dilatateur, est disposé dans l'extrémité avant du tube. Une boucle de fil, qui peut être attaché à une suture, est fixée à l'extrémité avant du raccord. Le sous-ensemble de gaine de protection comprend une gaine de protection et un élément de rétention. La gaine se présente comme un élément allongé possédant une extrémité proximale ouverte, une extrémité distale généralement conique et une lumière longitudinale. La gaine est configurée pour recevoir sensiblement la totalité du sous-ensemble d'implantation du cathéter, à l'exception de la boucle de fil, qui s'étend à travers une ouverture dans l'extrémité distale de la gaine. Une ou plusieurs zones fragiles sont ménagées à l'extrémité distale de la gaine et sont conçues pour se déchirer lorsque le renfort interne est tiré via l'extrémité distale. L'élément de rétention est fixé vers l'extérieur of la gaine et est configuré pour agir comme un arrêtoir d'insertion de la gaine dans le corps d'un patient.
