Surgical implement particularly useful for suturing prosthetic valves
First Claim
1. A surgical instrument to aid in suturing a prosthetic valve into a heart annulus, comprising:
- a manually grippable handle;
a holder carried at one end of the handle for releasably holding a prosthetic valve to be pre-loaded thereon;
a first ring fixed to the handle and having means for securing thereto one end of a plurality of sutures to be pre-loaded onto the handle with each suture carrying a needle at its opposite end passing through the prosthetic valve when pre-loaded on said handle;
and a second ring fixed to said handle and including a plurality of circumferencially-spaced projections each engageable with an intermediate portion of a suture for releasably retaining the plurality of sutures each pre-loaded in folded condition on the handle and extending longitudinally thereof;
said two rings being located on said handle such that each suture has a length between said prosthetic valve and said needle-carrying end of the suture which is at least twice the length of the suture between said secured one end and said prosthetic valve.
