ABSTRACT:
In general, the present invention comprises an holding apparatus for facilitating implantation of a prosthetic heart valve within a mammalian heart. The holding apparatus generally comprises a cage or enclosure having a heart valve prosthesis retention space defined therewith. The proximal end of the holding apparatus is releasably attached to the proximal end of the heart valve prosthesis such that, when the holding apparatus is advanced in a forward direction, a "pulling" force will be exerted upon the proximal end of the prosthesis, rather than a "pushing" force being exerted upon the distal end of the prosthesis. The releasable attachment of the prosthesis to the holding apparatus may be accomplished by any suitable attachment member, and preferably comprises a number of suture threads which are passed through the prosthesis and threaded upon the holding apparatus at location(s) which are easily accessible such that the surgeon may cut the suture threads to effect release of the heart valve prosthesis, during the prosthesis implantation procedure. Also described and claimed are associated methods for utilizing the above-described holding apparatus to effect implantation of a prosthetic heart valve.
