Abstract
Abstract A gastrostomy-jejunal feeding tube comprises a gastrostomy tube having an enlarged resiliently, collapsible retainer element on the distal end thereof and a jejunal feeding tube which is removably received in the gastrostomy tube in a manner which allows fluids to pass through the gastrostomy tube despite the presence of the jejunal feeding tube therein. The gastrostomy-jejunal feeding tube is adapted to be installed in a patient so that the gastrostomy tube extends through the stomach wall, fascia and skin for draining fluids from the stomach and so that the jejunal feeding tube extends into the jejunum area of the intestines for feeding and medicating the patient. Since the jejunal feeding tube is removable from the gastrostomy tube it can be replaced without surgery, and since the retainer element is resiliently collapsible, it can be pulled outwardly through the stomach wall to allow the gastrostomy tube to be removed from the patient without surgery.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
233 words
A gastrostomy-jejunal feeding tube comprising a gastrostomy tube including a tubular main portion having distal and proximal ends and an enlarged retainer element on the distal end of said main portion, and a jejunal feeding tube including a feeding tube element having distal and proximal ends and a weighted bolus on the distal end of said feeding tube element, said jejunal feeding tube being slidably received in said gastrostomy tube, said gastrostomy tube and said jejunal feeding tube being dimensioned so that said jejunal feeding tube, including said weighted bolus thereof, can pass through said gastrotomy tube to remove said jejunal feeding tube therefrom, said gastrostomy tube and said jejunal feeding tube being further dimensioned and configured so that fluids can pass through said gastrostomy tube despite the presence of said jejunal feeding tube therein and so that said gastrostomy-jejunal feeding tube is receivable in a patient with said gastrostomy tube extending through the stomach wall, fascia and skin of the patient and said retainer element in engagement with the inner surface of the stomach wall, and with the weighted bolus of said jejunal feeding tube received in the jejunum of the patient, said enlarged retainer element comprising a plurality of resilient flanges which extend outwardly from the distal end of said main portion and a plurality of hub portions which extend outwardly from said portion by a reduced amount between said flanges.
Claim 2
Dependent Claim
233 words
A gastrostomy-jejunal feeding tube comprising a gastrostomy tube including a tubular main portion having distal and proximal ends and an enlarged retainer element on the distal end of said main portion, and a jejunal feeding tube including a feeding tube element having distal and proximal ends and a weighted bolus on the distal end of said feeding tube element, said jejunal feeding tube being slidably received in said gastrostomy tube, said gastrostomy tube and said jejunal feeding tube being dimensioned so that said jejunal feeding tube, including said weighted bolus thereof, can pass through said gastrotomy tube to remove said jejunal feeding tube therefrom, said gastrostomy tube and said jejunal feeding tube being further dimensioned and configured so that fluids can pass through said gastrostomy tube despite the presence of said jejunal feeding tube therein and so that said gastrostomy-jejunal feeding tube is receivable in a patient with said gastrostomy tube extending through the stomach wall, fascia and skin of the patient and said retainer element in engagement with the inner surface of the stomach wall, and with the weighted bolus of said jejunal feeding tube received in the jejunum of the patient, said enlarged retainer element comprising a plurality of resilient flanges which extend outwardly from the distal end of said main portion and a plurality of hub portions which extend outwardly from said portion by a reduced amount between said flanges.
Claim 3
Dependent Claim
23 words
In the gastrostomy-jejunal feeding tube of claim 1, said flanges further characterized as extending outwardly in circumferentially spaced relation from said main portion.
Claim 4
Dependent Claim
17 words
In the gastrostomy-jejunal feeding tube of claim 1, said flanges further characterized as being of rounded configuration.
Claim 5
Dependent Claim
15 words
The gastrostomy-jejunal feeding tube of claim 1 further characterized as comprising three of said flanges.
Claim 6
Dependent Claim
18 words
In the gastrostomy-jejunal feeding tube of claim 1, said retainer portion being integrally formed with said main portion.
Claim 7
Dependent Claim
19 words
In the gastrostomy-jejunal feeding tube of claim 5, said gastrostomy tube being integrally formed from a nontoxic rubberized material.
Claim 8
Dependent Claim
76 words
The gastrostomy-jejunal feeding tube of claim 1 further comprising a Y-shaped tubular element, the stem of said Y-shaped tubular element being attached to the proximal end of said gastrostomy tube so that one leg of said Y-shaped tubular element communicates with the interior of said gastrostomy tube, said jejunal feeding tube being received in said Y-shaped tubular element so that it passes through the stem thereof and into the other leg of said Y-shaped tubular element.
Claim 9
Dependent Claim
23 words
In the gastrostomy-jejunal feeding tube of claim 1, said hub portions extending outwardly from said main portion by less than approximately 0.25 inches.
Claim 10
Dependent Claim
17 words
In the gastrostomy-jejunal feeding tube of claim 8, said hub portions extending outwardly by approximately 0.125 inches.
Claim 11
Dependent Claim
16 words
In the gastrostomy-jejunal feeding tube of claim 1, said flanges further characterized as being substantially flat.
Claim 12
Dependent Claim
120 words
A gastrostomy tube comprising a tubular main portion having distal and proximal ends and an enlarged retainer element on the distal end of said main portion, said gastrostomy tube being dimensioned and configured so that fluids can pass therethrough and so that it is receivable in a patient with said gastrostomy tube extending through the stomach wall, fascia and skin of the patient and with said enlarged retainer element in engagement with the inner surface of the stomach wall, said enlarged retainer element comprising a plurality of resilient flanges which extend outwardly from the distal end of said main portion and a plurality of hub portions which extend outwardly from said main portion by a reduced amount between said flanges.
