초록 ▼

The present invention provides a prosthetic heart valve holder specifically configured to hold a prosthetic heart valve comprised of a stent. The heart valve holder assembly has three main components: a handle, a valve capture loop assembly and a valve retainer. The prosthetic heart valve is secured to the valve retainer by a loop of suture as the surgeon sutures or attaches the valve to the annulus of the heart. Thus, the valve holder assembly facilitates attachment of the prosthetic valve to the annulus so that the procedure may be performed in a time and labor efficient manner.

대표청구항 ▼

A valve holder for holding a prosthetic heart valve having an inflow portion and an outflow portion so that the valve is (i) accurately positioned at an annulus of a patient\s heart remaining after removal of a patient\s diseased heart valve, (ii) temporarily held in place without substantially obstructing the valve while a surgeon or technician attaches the valve within the patient\s heart while said valve is temporarily held in place by the holder, and (iii) quickly and easily removed after the prosthetic heart valve has been permanently attached at said annulus, said valve holder comprising: a cup shaped retainer defining an inner cavity, said retainer having an open receiving end configured to accept said outflow portion of said prosthetic heart valve within said cavity; a valve capture loop assembly comprising a base, a loop of suture attached to said base, and a spring for biasing said base and its attached loop of suture; and a rod member inserted through said base and said spring and attached to said cup shaped retainer opposite its open receiving end, said rod member serving (i) as a handle for the surgeon or technician attaching said valve, (ii) for slidably mounting said base member, and (iii) for retaining said spring between said cup shaped retainer and said base of said valve capture loop assembly; said holder configured to capture said prosthetic heart valve to the holder with said loop of suture so that (i) only a very minimal area of said valve is obstructed when said valve is held in place within said patient\s heart, and (ii) configured such that said prosthetic heart valve is very easily removed from said holder after its attachment within said heart by simply cutting said loop of suture to completely release said prosthetic heart valve from said holder.
