Annuloplasty instrument
First Claim
1. A device for repairing a heart valve comprised of valve tissue including an annulus and a plurality of leaflets for allowing and preventing blood flow, the device comprising:
- an implantation instrument, comprising;
a first support ring, anda second support ring connected to said first support ring to form a coiled configuration, said first support ring configured to abut one side of the valve and said second support ring configured to abut an opposite side of the valve to thereby trap a portion of the valve tissue therebetween, and an annuloplasty implant adapted to be attached to the heart valve annulus in order to reshape the annulus and allow the leaflets to open and close properly, said annuloplasty implant being connected to the implantation instrument for insertion to the annulus, wherein the annuloplasty implant is removably attached to the second support ring of the implantation instrument such that the implantation instrument may be withdrawn from a patient after the annuloplasty implant has been attached to the heart valve annulus.

Abstract
A device for repairing a heart valve comprises an implantation instrument. The implantation instrument comprises a first support ring, and a second support ring connected to said first support ring to form a coiled configuration. The first support ring is configured to abut one side of the valve and the second support ring is configured to abut an opposite side of the valve to thereby trap a portion of the valve tissue therebetween. The device further comprises an annuloplasty implant adapted to be attached to the heart valve annulus in order to reshape the annulus and allow the leaflets to open and close properly. The annuloplasty implant is connected to the implantation instrument for insertion to the annulus.

14. A kit for repairing a heart valve comprised of valve tissue including an annulus and a plurality of leaflets for allowing and preventing blood flow, the kit comprising:
-
an implantation instrument, comprising; a first support ring, and a second support ring connected to said first support ring to form a coiled configuration, said first support ring configured to abut one side of the valve and said second support ring configured to abut an opposite side of the valve to thereby trap a portion of the valve tissue therebetween, and an annuloplasty implant adapted to be attached to the heart valve annulus in order to reshape the annulus and allow the leaflets to open and close properly, wherein the implantation instrument is adapted to temporarily reshape the heart valve annulus for allowing the annuloplasty implant to be attached to the heart valve annulus and the implantation instrument is adapted to be withdrawn from a patient after the annuloplasty implant has been attached to the heart valve annulus.

15. A method for repairing a heart valve comprised of valve tissue including an annulus and a plurality of leaflets for allowing and preventing blood flow, said method comprising:
-
inserting an implantation instrument comprising a first and a second support ring connected to each other to form a coiled configuration, said instrument being inserted such that valve tissue is trapped between the first and second support rings, attaching an annuloplasty implant to the annulus in order to reshape it, and removing the implantation instrument. - View Dependent Claims (16, 17)
