Abstract
The present invention relates to the correction of mitral and tricuspid valve regurgitation. More particularly this means that he leaflet bases of the posterior and anterior mitral leaflets are connected to each other with a stabilizing element (14) extended transversely across the valve annulus (13). Said stabilizing element (14) is by first (22) and second (24) ends secured into a first (26) and a second (28) position respectively at said valve annulus (13) by means of sutures, anchors or clips. Coaptation is attained, by reducing the length of the stabilizing element (14) from D1 to D2.
Claims28
A method for the repair of a cardiac valve (2) provided with an anterior (4) and posterior (6) leaflet, each being protruding from a corresponding leaflet base (8;
- 10) at the valve annulus (13), comprising the following steps:
- modifying said cardiac valve (2) by bringing at least one stabilizing element (14) into a selected position (26;
- 28) at each of the leaflet bases (8, 10);
- interconnecting said leaflet bases by extending said stabilizing element (14) across the cardiac valve (2) and;
- determining the distance (D1, D2) between the anterior (8) and posterior (10) leaflet bases by means of said stabilizing element (14).
A method for the repair of a cardiac valve (2) provided with an anterior (4) and posterior (6) leaflet, each being protruding from a corresponding leaflet base (8;
- 10) at the valve annulus (13), comprising:
- entering a stearable applicator (32) endovascularly into the left atrium;
- modifying said cardiac valve (2) by using said stearable applicator (32) for performing the following steps:
- bringing at least one stabilizing element (14) into a selected position (26;
- 28) at each of the leaflet bases (8, 10);
- interconnecting said leaflet bases by extending said stabilizing element (14) across the cardiac valve (2) and;
- determining the distance (D1, D2) between the anterior (8) and posterior (10) leaflet bases by means of said stabilizing element (14).
A method for the repair of a cardiac valve (2) provided with an anterior (4) and posterior (6) leaflet, each being protruding from a corresponding leaflet base (8;
- 10) at the valve annulus (13), comprising the following steps:
- modifying said cardiac valve (2) by bringing a first end (22) of at least one stabilizing element (14) into a first selected position (26) of the valve annulus (13) and a second end (24) of said at least one stabilizing element (14) into a second selected position (28) of the valve annulus (13);
- interconnecting said leaflet bases (8;
- 10) by extending said stabilizing element (14) across the cardiac valve (2) and;
- determining the distance (D1, D2) between the anterior (8) and posterior (10) leaflet bases by means of said stabilizing element (14).

- bringing a first end (22) of at least one stabilizing element (14) into a first selected position (26) of the valve annulus (13) and a second end (24) of said at least one stabilizing element (14) into a second selected position (28) of the valve annulus (13);
- interconnecting said leaflet bases (8;
- 10) by extending said stabilizing element (14) across the cardiac valve (2) and;

A means for the repair of a cardiac valve (2) comprising an anterior (4) and posterior (6) leaflet, each being protruding from a corresponding leaflet base (8;
- 10) at the valve annulus (13), said means being arranged for modifying said cardiac valve (2), in which the distance (D1, D2) between the anterior (8) and posterior (10) leaflet bases is determined by means of at least one stabilizing element (14), which has been brought into a selected position (26;
- 28) at each of the leaflet bases (8, 10), said leaflet bases being interconnected by means of said stabilizing element (14) which is extended across the cardiac valve (2).
