Device and a method for treatment of atrioventricular regurgitation
DCFirst Claim
1. A device for treatment of atrioventricular regurgitation in a heart, comprisinga suturing means having such dimensions as to be introducible, via blood vessels leading to the heart, to two leaflets of an atrioventricular valve between an atrium and a corresponding ventricle of the heart and being capable of binding together the two leaflets in a position along the free edges of the leaflets, whereby the closing of the atrioventricular valve is improved, said suturing means being transitional between two states, being open in a first state and substantially closed in a second state, and said suturing means being biased towards its second state.

Abstract
A device for treatment of atrioventricular regurgitation comprises a suturing means. The suturing means has such dimensions as to be introducible, via blood vessels leading to the heart, to two leaflets of the atrioventricular valve between an atrium and a corresponding ventricle of the heart. Further, the suturing means is designed for binding together the two leaflets in a position along the free edges of the leaflets. As a result, the closing of the valve is improved.
A method of using the device comprises the steps of inserting the suturing means into a catheter, introducing the catheter to the heart, so as to position a distal end of the catheter close to two leaflets of an atrioventricular valve, capturing the free edges of the two leaflets with the suturing means in its open state, binding together the two leaflets by transition of the suturing means into its closed state, and retracting the catheter from the heart.

13. A device for the treatment of atrioventricular regurgitation in a heart, comprising
a suturing means having such dimensions as to be introducible, via blood vessels leading to the heart, to two leaflets of an atrioventricular valve between an atrium and a corresponding ventricle of the heart and being designed for binding together the two leaflets in a position along the free edges of the leaflets, whereby the closing of the atrioventricular valve is improved, wherein the suturing means is transitional between two states, being open in a first state and substantially closed in a second state, wherein the suturing means comprises a clip, wherein the clip has two arms pivotally connected to each other at a first end thereof, the arms forming a V in the first state of the clip and being substantially parallel in the second state of the clip, and wherein the two pairs of arms of the clip are connected to each other by two crossbars near the connected first ends of the arms.

14. A device for the treatment of atrioventricular regurgitation in a heart, comprising a suturing means having such dimensions as to be introducible, via blood vessels leading to the heart, to two leaflets of an atrioventricular valve between an atrium and a corresponding ventricle of the heart and being designed for binding together the two leaflets in a position along the free edges of the leaflets, whereby the closing of the atrioventricular valve is improved,
wherein the suturing means is transitional between two states, being open in a first state and substantially closed in a second state, wherein the suturing means comprises a clip, and further comprising a catheter for introduction of the clip via the blood vessels to the heart, said catheter having an outermost sheet covering the clip and being retractable therefrom.
