PARAVALVULAR LEAK DETECTION, SEALING AND PREVENTION
First Claim
1. A prosthetic valve assembly for placement in a body vessel and sealing of a paravalvular leak, the valve assembly comprising:
- a prosthetic valve;
a peripheral wall having an inner surface configured to support the prosthetic valve and an outer surface configured to abut the body vessel and secure the peripheral wall therein;
a seal extending outward from at least a portion of the outer surface of the peripheral wall, the seal configured for expansion, after implantation of the peripheral wall in the body vessel, to seal the paravalvular leak between the peripheral wall and the body vessel.

Abstract
The present invention provides a series of new percutaneous concepts of paravalvular repairs including identifying the leak location, several repair techniques and finally built-in means for leak prevention, built on percutaneous valves. A catheter-delivered device locates cavities occurring between a prosthetic valve and the wall of the body vessel where the valve is implanted, the cavities producing paravalvular leaks during diastole, the device comprising at least one of a plurality of flexible wires, the wire having attached to it a balloon, wherein the balloon is pulled by the leak through the cavity and wherein the wire then serves to mark the cavity location.

17. A method of implanting a prosthetic valve assembly, the method comprising:
-
implanting a peripheral wall and prosthetic valve surrounded and supported by the peripheral wall into a body vessel; and
,after implanting the peripheral wall, expanding a seal supported on an outside surface of the peripheral wall to seal a paravalvular leak. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)
