Abstract

In annuloplastic surgery, the holder which supports the annuloplasty ring during the suturing of the ring to a heart valve annulus is released from its handle, and reattached for subsequent removal, without rotary or axially compressive stress on the holder. This is accomplished by inserting laterally movable locking tabs from the handle into the holder. The locking tabs are the ends of a Y-shaped clip which translates the axial movement of a locking button on the handle into a transverse holder-engaging movement.

Claims

1. An annuloplasty holder system, comprising:

a) a holder adapted to hold an annuloplasty ring;

b) a handle having an end arranged to be releasably engaged with said holder;

c) a plurality of tabs on said handle, said tabs being movable transversely of said handle and being arranged to releasably lockingly engage said holder when moved transversely outwardly of said handle;

d) a tab moving member positioned on said handle, said tab moving member being longitudinally movable with respect to said handle and arranged to move said tabs transversely to engage said holder when said tab moving member is longitudinally moved; and

e) an actuating member on the outside of said handle connected to said tab moving member for moving the same.

2. The system of claim 1, in which said tab moving member is a flexible, substantially Y-shaped element, said tabs being formed on the ends of the branches of the Y, and the branches of said Y-shaped element being bent to move transversely of said handle when the stem of the Y is moved longitudinally of said handle.

3. The system of claim 1, in which said handle has a malleable portion and a rigid portion, said tab moving member and said actuating member being positioned in said rigid portion.

4. The system of claim 1, in which said handle carries at its holder-engaging end a template marking the locations for proper placement of sutures on said annuloplasty ring.
