First Claim
1. A gastrojejunal feeding system comprising:
- an adapter, said adapter including a body having a protrusion extending from said body with a primary lumen formed through said protrusion, said body further including a channel formed through said body in communication with said primary lumen and extending through said body at a generally perpendicular angle relative to said primary lumen;
a gastrostomy tube, said gastrostomy tube having a distal end and a proximal end with a lumen formed therebetween, said distal end in communication with a visceral organ of a patient and said proximal end being attachable to said protrusion of said adapter; and
a feeding tube having a distal end and a proximal end, said proximal end being insertable through said gastrostomy tube and said adapter;
wherein said feeding tube extends from said adapter at a low profile relative to a patient.

Abstract
The present invention is a low profile jejunal adapter for a low profile gastrostomy tube. Once properly attached, the jejunal adapter converts the low profile gastrostomy tube into a gastrojejunostomy tube. Specifically, the jejunal adapter includes a feeding tube which is positioned within the jejunum of a patient and a venting lumen which provides for simultaneous venting of gases collected in the patient'"'"'s stomach while fluid is being fed to the jejunum through the feeding tube. In a preferred embodiment, the length of the feeding tube is adjustable to accommodate various patients. In an alternative embodiment, the length of the feeding tube is fixed to reduce the manufacturing costs of this device. The jejunal adapter of this invention also includes a cap retention mechanism for securing the cap of the gastrostomy tube and a latch mechanism adapted to secure the jejunal adapter to the gastrostomy tube.

26. A method for a feeding fluid to a jejunum while simultaneously evacuating gas from a visceral organ of a patient using a gastrojejunal feeding system comprising an adapter, the adapter including a body having a protrusion extending from the body with a primary lumen in communication with a channel formed through a body, the body further including a venting lumen with a tubular extension attached to the venting lumen and a primary port in communication with the channel, the tubular extension including a cap for sealing the tubular extension, a gastrostomy tube having a distal end and a proximal end with a lumen formed therebetween, the distal end being in communication with a visceral organ of a patient and the proximal end being attachable to the protrusion of the adapter, the primary lumen and the venting lumen being in communication with the lumen of the gastrostomy tube, a feeding tube having a distal end and a proximal end, the method comprising the steps of:
-
a) threading the distal end of the feeding tube through the primary lumen;
b) directing the distal end of the feeding tube through the gastrostomy tube;
c) feeding the distal end of the feeding tube through a visceral organ and into the jejunum of a patient;
d) attaching the adapter to the gastrostomy tube;
e) directing the proximal end of the feeding tube along the channel and outward through the primary port;
f) cutting off the proximal end of the feeding tube and attaching the proximal end of the feeding tube to a feeding set in communication with a source of fluid;
g) providing fluid to a jejunum of a patient through the feeding tube; and
h) removing the cap from the tubular extension and permitting gas to evacuate from a visceral organ of a patient. - View Dependent Claims (27, 28, 29)
