Abstract

An anastomotic connector includes a tubular shell and a porous biocompatible liner configured to connect two or more natural and/or artificial lumens, such as blood vessels and/or grafts. The tubular shell may be bioabsorbable, ultimately dissolving in the body, while the biocompatible liner can remain in the body and connected to the lumens.

Claims

1. An anastomotic connector comprising:

a tubular shell comprising an abluminal surface, a luminal surface, and two ends, at least one of the two ends comprising a liner retention means; and

a porous polymeric biocompatible liner, wherein the porous polymeric biocompatible liner covers at least the luminal surface of the tubular shell.

2. The anastomotic connector according to claim 1 wherein the tubular shell comprises a bioabsorbable material.
