Abstract

A device for correcting mitral and tricuspid valve regurgitation. The device connects the leaflet bases of the posterior and anterior mitral leaflets to each other with a stabilizing element extended transversely across the valve annulus. The stabilizing element is by first and second ends secured into a first and a second position respectively at the valve annulus using sutures, anchors or clips. Coaptation is attained, by reducing the length of the stabilizing element.

Claims

1. 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).

5. A method according to claim 1, comprising the step of:

adjusting the distance (D1, D2) between the anterior (8) and posterior (10) leaflet bases by varying the length of said stabilizing element (14).

6. A method according to claim 1, comprising the step of:

attaching the stabilizing element (14) to the atrial side of each leaflet base (8;

10), said stabilizing element (14) serving as a support for said leaflets (4, 6).

7. A method according to claim 6, comprising the steps of:

tightening the stabilizing element (14), in case of a prolaps, by means of shortening its length between its selected positions (26;

28) at said leaflet bases (8;

10) close to the apposition line (0) of the leaflets (4, 6) (the orifice plane of the valve), thereby extending said stabilizing element 14 straightly between said selected positions (26;

28);

locating even a central part of said stabilizing element 14 between said leaflet bases (8;

10) close to the apposition line (0) of the leaflets (4, 6) and;

at the same time positioning the leaflet bases (8;

10) mutually closer and attaining coaptation of the leaflets (4, 6).

2. 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).

8. A method according to claim 2, comprising the steps of:

encasing said stearable applicator (32) (catheter) in an inserting device (guidance sheath) for penetrating the human skin and achieving a venous access port;

extending the stearable applicator (32) from a maneuvering device at a proximal end outside said access port, through the femoral vein, the inferior vena cava and the right atrium to penetrate the intraatrial septum to the left atrium and;

arranging the stearable applicator (32) (catheter) with a manipulative distal end (31) in one of said selected positions (26;

28).

9. A method according to claim 8, which is comprised of assessing said selected position (28) to the posterior mitral leaflet base (10).

10. A method according to claim 8, which is comprised of assessing said selected position (26) to the anterior mitral leaflet base (8).

11. A method according to claim 2, comprising the step of:

adjusting the distance (D1, D2) between the anterior (8) and posterior (10) leaflet bases by varying the length of said stabilizing element (14).

14. A method according to claim 2, comprising the step of:

attaching the stabilizing element (14) to the atrial side of each leaflet base (8;

10), said stabilizing element (14) serving as a support for said leaflets (4, 6).

3. 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).

12. A method according to claim 3, comprising the step of:

adjusting the distance (D1, D2) between the anterior (8) and posterior (10) leaflet bases by varying the length of said stabilizing element (14).

15. A method according to claim 3, comprising the step of:

attaching the stabilizing element (14) to the atrial side of each leaflet base (8;

10), said stabilizing element (14) serving as a support for said leaflets (4, 6).

4. 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 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;
