Low-profile enterostomy device
First Claim
1. An enterostomy device comprising:
- a hollow stoma tube having a first end and a second end;
a port disposed on the first end of the stoma tube and configured for passing fluids therethrough, the port being movable between a first position wherein fluid may be injected into but not withdrawn from the stoma tube, a second position wherein fluid may be withdrawn from but not injected into the stoma tube, and a third position wherein the port is not in fluid communication with the stoma tube;
an inflatable retaining member, the inflatable retaining member being attached to the stoma tube adjacent the second end of the stoma tube such that the inflatable retaining member is spaced apart from the stoma tube and wherein the inflatable retaining member is spaced apart from the stoma tube by an noninflatable skirt of material; and
an inflation line disposed along the stoma tube and in fluid communication with the inflatable retaining member.

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.
