A holder for a highly flexible tissue-type heart valve is disclosed that maintains an implant shape to the valve. The holder may have cusp and commissure contacting supports, and may be attached at all six such supports, or only three. The holder may be flexible to permit inward flexing of the heart valve during implant for greater visibility when implanting using a running suture method. The holder may be formed of flexible wires such as Nitinol, and shaped to resist excessive axial and torsional deformation of the valve. A short handle connector suitable for manual grasping may be attached and stored with the valve, with the handle connector having a coupling for receiving a longer delivery handle. A two stage holder may be utilized to accommodate different implant methods.

Holder for flexible heart valve

A slide closure for joining overlapping edges of flexible or rigid substrates having complementary touch fasteners thereon. The slide closure has a pair of closing surfaces facing each other and structure joining the closing surfaces together so as to define two channels opening in opposite directions. The substrates are received within the channels such that they overlap between the closing surfaces. The closing surfaces converge to a nip having a dimension small enough to cause the complementary touch fasteners to engage when the slide closure is displaced along the overlapping edges in a first direction. The slide closure may further include a spanning member disposed generally between the closing surfaces that serves to structurally join the closing surfaces, partly define the channels on either side, and provide diverging separating surfaces that cause the complementary touch fasteners to disengage when the slide closure is displaced in a second direction opposite the first direction. The touch fasteners may be Velcro or the like, and a slide closure may include a strap bracket for ease of manipulation. Guide grooves within the slide closure may be provided to receive ribs or other such features on the substrates and maintain the substrates within the slide closure.
