Abstract

An improved apparatus and method for AAC insertion including a new AAC connector having a threaded or partially threaded body. The AAC connector has a flexible flange situated at one end that is soft and thin enough to bend backwards so that it can be pushed through an opening made in the apex, but rigid enough to flex back to its original position and hold its shape once it enters the interior of the left ventricle. A second ring is also provided that is adapted to be deployed over the body of the connector and against the exterior wall of the apex.

Claims

1. An apicoaortic conduit connector comprising:

a tube having proximal and distal ends, and inside and outside surfaces;

a flexible flange disposed at or near said distal end;

a securing ring adapted to fit over said tube.

2. An apicoaortic conduit connector according to claim 1 further comprising threading on at least a portion of said outside surface of said tube and corresponding threading on an inside diameter of said securing ring.

3. An apicoaortic conduit connector according to claim 1 wherein said flexible flange is sufficiently flexible to deform sufficiently to allow the proximal end of said connector, together with said flange, to be inserted through an opening in a left ventricle, said opening having a diameter equal to or less than the diameter of said tube.

4. An apicoaortic conduit connector according to claim 3 wherein said flexible flange has sufficient shape memory that once it has been deformed to allow insertion of the proximal end of said connector into said opening in a left ventricle, it will return to its original shape.

5. An apicoaortic conduit connector according to claim 1, further comprising a biasing device attached at one end to said tube, and attached at another end to a proximal surface of said securing ring.

6. An apicoaortic conduit connector according to claim 5, further comprising a release device attached at one end to said securing ring, and releasably attached at another end to said tube, and releasably holding said biasing device in compression.
