Abstract:
1. A device for providing a channel between a stomach lumen and abdominal skin of a patient, the device comprising: a relatively rigid protective tube constructed to resist deformation or collapse comprising a generally tubular wall having an outer surface, a proximal end and a distal end defining a length of the protective tube, and an opening in each end which extends through the protective tube to define an inner surface of the tubular wall, wherein the protective tube is configured to be positioned in a stoma extending between a stomach lumen and a patient's abdominal skin to provide a channel therebetween, wherein a portion of the protective tube is configured to be removed at the proximal end to reduce the length, and wherein the protective tube is not adapted for the transmission of fluids; a first bolster provided adjacent to the distal end of the protective tube, the first bolster configured to be positioned against an internal wall of a patient's stomach such that when the distal end of the protective tube is positioned in a patient's stomach, the first bolster is configured to extend outward, away from the protective tube such that it is sealingly positioned against the internal wall so as to minimize or avoid fluid leakage through the stoma; a second bolster provided adjacent the proximal end of the protective tube and configured to permit the protective tube to pass therethrough, the second bolster movable over the protective tube and configured to be secured to the protective tube to permit it to be positioned against the patient's abdominal skin, the second bolster having a proximal surface, a distal surface and an opening therethrough, the protective tube positioned through the opening of the second bolster such that when the distal end of the protective tube is positioned in the patient's stomach lumen and the first bolster is sealingly positioned against the internal wall of the stomach lumen, the second bolster is moved over the protective tube such that its distal surface is positioned against the patient's abdominal skin, wherein the second bolster is configured to maintain a position on the outer surface of the protective tube, and wherein the second bolster includes a spring clip which engages the outer surface of the protective tube such that the second bolster is maintained in the position, the second bolster configured to releasably couple to at least a portion of a feeding device; and a feeding device including a head and a shaft extending therefrom, the head and the shaft positioned in a perpendicular orientation relative to each other, the head including at least one opening formed therein in communication with an opening provided through the shaft, the head further including a distal surface configured to be positioned against and releaseably coupled to at least a portion of the proximal surface of the second bolster, and wherein when the feeding device is coupled to the second bolster, the head of the feeding device and the second bolster are positioned in a generally parallel alignment relative to each, the distal surface of the second bolster is positioned against the patient's abdominal skin and the shaft of the feeding device is positioned through the protective tube such that a distal portion of the shaft extends a distance from the distal end of the protective tube to provide transmission of fluids from the opening in the head, wherein the shaft is configured such that a substantial portion of an outer surface of the shaft is positioned against a substantial portion of the inner surface of the protective tube, and wherein a diameter of the substantial portion of the outer surface of the shaft slidably abuts a diameter of the substantial portion of the inner surface of the protective tube to prevent backflow of fluid through the protective tube when fluid is introduced to a patient's stomach via the opening in the head and the shaft of the feeding device.
