Abstract

A device for improving the function of a heart valve comprises a first loop-shaped support, which is configured to abut a first side of the heart valve, and a first flange unit being connected to said first loop-shaped support. The flange unit is configured to be arranged against said annulus when said first loop-shaped support is abutting said heart valve.

Claims

1. A method of implanting an annuloplasty device, the method comprising:

directing an annuloplasty device to a native heart valve;

the annuloplasty device comprising a first and second loop-shaped support, the first loop-shaped support being continuous with the second loop-shaped support to form a coil-shaped body,

inserting an end of the second loop-shaped support through a natural opening of the native heart valve formed between leaflets of the native heart valve at a commissure of the leaflets of the native heart valve,

rotating the second loop-shaped support into place on a second side of the native heart valve, opposite a first side of the native heart valve such that the second loop-shaped support abuts the second side,

placing the first loop-shaped support to abut the first side to trap a portion of the native heart valve between the first and second loop-shaped supports;

fixating a heart valve prosthesis to the annuloplasty device, and

anchoring at least one of said first and second loop-shaped supports into tissue at the native heart valve for said implanting of the annuloplasty device.

2. The method of implanting an annuloplasty device according to claim 1, wherein the annuloplasty device further comprises a shape memory material.

3. The method of implanting an annuloplasty device according to claim 1, wherein the first and/or second loop-shaped support has a varying width along its extension.
