Tissue ingrowth intestinal bypass sleeve and method of deployment

摘要

A device and method for deploying an intestinal sleeve is disclosed. The intestinal sleeve has an impermeable layer and a tissue ingrowth layer. The intestinal sleeve is temporarily anchored to the wall of a patient's duodenum and the wall tissue grows into the tissue ingrowth layer anchoring the intestinal sleeve within the patient's duodenum.

主权项

1. A catheter assembly for deploying an endoluminal sleeve, the catheter assembly having an axis and comprising:
a first catheter having a distal portion, a proximal portion, and a first outside diameter; a balloon disposed at the distal portion of the first catheter, the balloon having an inflated configuration in which a balloon diameter is greater than the first outside diameter and a deflated configuration; a sleeve having a lumen, the balloon being internal to the lumen, the sleeve being wrapped about the catheter assembly axis and having a porous outer ingrowth layer and an impermeable inner layer, the outer ingrowth layer being configured to promote issue ingrowth and having an outer surface with at least one temporary attachment mechanism for attachment to a body lumen; and a second catheter disposed about the first catheter and being slidable from a first position in which the second catheter covers the balloon and a second position in which the second catheter does not cover the balloon.
