TEMPORARY OSTOMY APPLIANCE
First Claim
1. A temporary ostomy appliance comprising:
- a transcecal catheter for extending through the abdominal wall into the large intestine and through the cecal valve into the ileum, the catheter including a first tubular portion intended to be received in the ileum, and a second tubular portion intended to be received at the cecal valve, the first and second tubular portions defining a drainage channel therein, and the second tubular portion being more easily collapsible, to collapse the drainage channel, than the first tubular portion.

Abstract
A temporary ostomy appliance is disclosed, including a catheter for extending through the abdominal wall into the intestine. The catheter may be a transcecal catheter for extending through the cecal valve into the ileum. A portion of a catheter that extends through the cecal valve is made collapsible when the catheter is empty. The collapsed portion expands to permit passage of effluent. A balloon carried on the catheter is preformed with a shape and size in order to permit inflation without elastic stretching of the balloon wall material. A filament is provided for permitting a portion of the catheter to be fastened to internal body tissue by surgical sutures or staples. In order to release the fastening without further surgery, the filament is withdrawn by pulling on a proximal portion outside the body.

8. A temporary ostomy appliance comprising:
-
a catheter for extending through the abdominal wall into the intestine; and an inflatable balloon carried on the catheter for inflation to engage intestinal tissue, the inflatable balloon being made of flexible material defining a hollow bladder of predetermined size that is not substantially smaller than the size of the balloon when inflated in use against the intestinal tissue. - View Dependent Claims (9, 10, 11)

12. A temporary ostomy appliance comprising:
-
a catheter for extending through the abdominal wall into the intestine, the catheter having a first portion accessible in use from outside the abdominal wall and a second portion that is received in use inside the body; a filament that extends between first and second eyes at the second catheter portion, to define a bridge feature that is fastenable to internal body tissue during surgery by a surgical suture or a surgical staple, the filament extending to the first portion of the catheter; wherein in use, the filament is withdrawable from the eyes by pulling on a portion of the filament at the first portion. - View Dependent Claims (13, 14, 15)
