Low-profile enterostomy device
First Claim
1. An enterostomy device comprising:
- a hollow stoma tube having a first end and a second end and a long axis extending therebetween;
a low-profile port hub secured to said first end of said stoma tube for selectively provided ingress and egress of fluids through said stoma tube, the low-profile port hub having an opening disposed in communication with and perpendicular to the hollow stoma tube;
a retaining member attached to said second end of said stoma tube and extending therefrom, said retaining member having an inflatable ring portion attached to the second end and spaced away from the stoma tube;
an inflation line positioned in proximity to said stoma tube and being in fluid communication with said inflatable ring of said retaining member; and
wherein said retaining member further comprises a skirt of flexible material encircling said second end of said stoma tube and attaching said second end to said inflating ring.

Abstract
An enterostomy device for providing fluids and nutrients through a stoma formed through the abdominal wall of a patient is described. The enterostomy device, which may be configured as either a gastrostomy device or a jejunostomy device, comprises a low-profile retaining member which is configured to be unobtrusively positioned within the stomach or the intestine, and which is configured to provide sufficient surface area for contacting the stomach or intestine to prevent unintentional removal or release of the enterostomy device from the patient. The enterostomy device is also structured with a low-profile port hub for facilitating the inflation of the retaining member and feeding and venting through the stoma.

11. A method of delivering fluids to a patient through a stoma formed through the abdominal wall of the patient comprising:
-
providing a gastrostomy device having a stoma tube, a port hub, and inflation line and a retaining member comprised of an inflatable ring extendable from said stoma tube, said retaining member being initially housed within said stoma tube for deployment;
positioning said stoma tube of said gastrostomy device through an existing stoma formed through the abdominal wall of the patient;
initiating ejection of said retaining member from said stoma tube; and
inflating said inflatable ring with said fluid until said inflatable ring is in contact with the lining of the patient'"'"'s stomach. - View Dependent Claims (12, 13, 14)
