ARRANGEMENT, A LOOP-SHAPED SUPPORT, A PROSTHETIC HEART VALVE AND A METHOD OF REPAIRING OR REPLACING A NATIVE HEART VALVE
First Claim
1. A method of repairing or replacing a native heart valve, comprising:
- positioning a loop-shaped support, comprising an inner segment and an outer segment, at an annulus of a native heart valve so that said outer segment of said loop-shaped support is positioned towards said annulus or surrounding valve tissue;
advancing a prosthetic heart valve through said loop-shaped support and positioning an outer surface of said prosthetic heart valve towards said inner segment, so as to prevent paravalvular leakage or regurgitation between said prosthetic heart valve and said annulus of said native heart valve.

Abstract
The present disclosure relates to an arrangement, a loop-shaped support, a prosthetic heart valve and a method of repairing or replacing a native heart valve. With the method or the arrangement, leakage or regurgitation between a prosthetic heart valve and the surrounding valve tissue is prevented. In one embodiment, an arrangement for replacement or repair of a native heart valve is provided, which comprises a loop-shaped support 41 and a prosthetic heart valve 70 and wherein an outer segment 32 of the loop-shaped support 41 is positionable towards surrounding valve tissue of a native heart valve and wherein an outer surface 74 of the prosthetic heart valve 70 is positionable towards an inner segment 34 of the loop-shaped support 41 so as to prevent paravalvular leakage or regurgitation between the prosthetic heart valve 70 and the surrounding valve tissue of the native heart valve.

15. A method of repairing or replacing a native heart valve, comprising:
-
delivering a loop-shaped support to a target site, advancing a radially expandable prosthetic heart valve through the loop-shaped support, said loop-shaped support has a circumference which is larger than a circumference of said prosthetic heart valve, and radially downsizing said loop-shaped support to fit tightly around said prosthetic heart valve so as to seal the area between said prosthetic heart valve and said loop-shaped support. - View Dependent Claims (16, 17, 18)
