## Abstract

A device for cardiac surgery is disclosed, having a) a plurality of pairs of suture guides spaced about the frame; b) a plurality of suture tubes, with one suture tube corresponding to each pair of suture guides; c) a plurality of snares, each corresponding to and passed through one of the plurality of suture tubes so that a handle at one end of the snare protrudes from a proximal end of the corresponding suture tube and a snare loop at another end of the snare protrudes through a distal end of the corresponding suture tube, and wherein the snare loop further protrudes through one of the suture guides in the corresponding pair of suture guides; and d) a plurality of sutures, each corresponding to one of the pairs of suture guides and coupled to the suture guide in the corresponding pair of suture guides which does not have the snare loop passing through it.

## Claims

### Claim 1

A device for cardiac surgery, comprising:
a frame;
a plurality of pairs of suture guides spaced about the frame;
a plurality of suture tubes, with one suture tube corresponding to each pair of suture guides;
a plurality of snares, each corresponding to and passed through one of the plurality of suture tubes so that a handle at one end of the snare protrudes from a proximal end of the corresponding suture tube and a snare loop at another end of the snare protrudes through a distal end of the corresponding suture tube, and wherein the snare loop further protrudes through one of the suture guides in the corresponding pair of suture guides; and
a plurality of sutures, each corresponding to one of the pairs of suture guides and coupled to the suture guide in the corresponding pair of suture guides which does not have the snare loop passing through it.

### Claim 2 (depends on 1)

The device of claim 1, wherein each of the plurality of sutures is coupled to its corresponding suture guide by a tied knot.

### Claim 3 (depends on 1)

The device of claim 1, wherein each of the plurality of sutures is coupled to its corresponding suture guide by a mechanical knot.

### Claim 4 (depends on 3)

The device of claim 3, wherein the mechanical knot is coupled to the frame.

### Claim 5 (depends on 1)

The device of claim 1, wherein each of the plurality of sutures has a needle coupled to an end of the suture opposite another end of the suture which is the one coupled to the corresponding suture guide.
