Medical anastomosis apparatus
First Claim
1. A connector for use in making an anastomotic connection between tubular body fluid conduits in a patient comprising a unitary structure disposed annularly about a longitudinal axis and having axially spaced first and second portions, said first portion having a plurality of annularly spaced first members that are deflectable radially out from a remainder of said structure, said second portion having a plurality of annularly spaced second members that are deflectable radially out from a remainder of said structure, and said structure being configured for annular enlargement, in use, along its entire length parallel to the longitudinal axis.

Abstract
A connector for use in providing an anastomotic connection between two tubular body fluid conduits in a patient. The connector is preferably a single, integral, plastically deformable structure that can be cut from a tube. The connector has axial spaced portions that include members that are radially outwardly deflectable from other portions of the connector. The connector is annularly enlargeable so that it can be initially delivered and installed in the patient in a relatively small annular size and then annularly enlarged to provide the completed anastomosis. The radially outwardly deflected members of the first and second portions respectively engage the two body fluid conduits connected at the anastomosis and hold those two conduits together in fluid-tight engagement. Apparatus for use in delivering and deploying a connector is also disclosed.
