Abstract
A system for bypassing an anastomosis site in a hollow organ is provided. The system includes a sleeve configured for spanning the anastomosis site at an internal surface of the hollow organ and a band configured for attachment to an external surface of the hollow organ and limiting migration of the sleeve beyond the anastomosis site.
Claims13
A system for internally shielding an anastomosis site, the system comprising:
- (a) an intra-luminal sheath positionable in a colon of a subject and being configured to migrate up and down the colon;
- and
- (b) a linear strip having a first portion configured for closing into a band of a predetermined diameter capable of encircling said colon upstream of the anastomosis site without applying compressive forces to walls of the colon, said band being for stopping down migration of said intra-luminal sheath under peristalsis such that the anastomosis site is shielded by said intra-luminal sheath during defecation, wherein a second portion of said linear strip is extendible out of a body of said subject when said band is positioned around said colon.
A method of internally shielding an anastomosis site, the method comprising:
- (a) positioning an intra-luminal sheath in a colon of a subject with at least a distal portion being upstream the anastomosis site;
- and
- (b) attaching a linear strip outside said colon upstream of the anastomosis site with a portion of said linear strip residing outside a body of said subject;
- and
- (c) closing said linear strip around said colon to form a band of a predetermined diameter such that compressive forces are not applied to walls of said colon;
- thereby stopping down migration of said intra-luminal sheath under peristalsis such that the anastomosis site is shielded by said intra-luminal sheath during defecation.
