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.

Claims

1. A method of replacing a heart valve of a patient, the method comprising:

inserting an implantation instrument comprising a first and a second support ring connected to each other to form a coiled configuration and a replacement valve being attached to the second support ring into the patient,

said instrument being inserted through an opening of the heart valve and brought to a corner of the opening between two leaflets of the heart valve such that valve tissue is trapped between the first and second support rings,

attaching the replacement valve to the valve tissue, and

removing the implantation instrument.

2. The method according to claim 1, wherein the valve tissue is an annulus associated with a native heart valve.

3. The method according to claim 1, wherein the step of inserting comprises

inserting a first end of the first support ring through the opening of the heart valve and bringing the implantation instrument to the corner of the opening between the two leaflets of the heart valve,

rotating the implantation instrument to position the first support ring on a first side of the valve, and

positioning the second support ring on an opposite second side of the valve.

4. A method of treating a heart valve in a patient, the method comprising:

inserting an implantation instrument into a patient;

trapping a valve tissue between a first ring and a second ring of said implantation instrument by inserting the implantation instrument through an opening of the heart valve and bringing the implantation instrument to a corner of the opening between two leaflets of the heart valve;

attaching a valve treatment device to said valve tissue;

removing said implantation instrument.

5. The method of claim 4, wherein said valve treatment device is a replacement valve.

6. The method of claim 4, wherein said valve treatment device is an annuloplasty ring.

7. The method of claim 4, wherein said implantation instrument further comprises a coiled member forming said first ring and said second ring.

8. The method according to claim 4, wherein said step of inserting an implantation instrument into a patient further comprises:

inserting a first end of said first ring through the opening between the two leaflets of the heart valve,

rotating said implantation instrument to position said first ring on a first side of said valve, and

positioning said second ring on an opposite second side of said valve.

9. A method of treating a heart valve in a patient, the method comprising:

inserting an implantation instrument into a patient;

trapping a valve tissue between a first ring and a second ring of said implantation instrument by inserting the implantation instrument through an opening of the heart valve and bringing the implantation instrument to a corner of the opening between two leaflets of the heart valve;

attaching an annuloplasty ring to said valve tissue;

removing said implantation instrument.

10. The method according to claim 9, wherein said valve tissue is an annulus associated with a native heart valve.

11. The method according to claim 9, wherein said step of inserting an implantation instrument into a patient further comprises:

inserting a first end of said first ring through the opening of the heart valve and bringing the implantation instrument to a corner of the opening between the two leaflets of the heart valve,

rotating said implantation instrument to position said first ring on a first side of said valve, and

positioning said second ring on an opposite second side of said valve.

12. The method of claim 9, wherein said implantation instrument further comprises a coiled member forming said first ring and said second ring.
