Abstract
A heart valve prosthesis includes a cylindrical valve cage stent constructed to be implanted percutaneously in the planar axis of a native valve annulus, an elastic and compressible, multi-leaflet valve insertable percutaneously into the body, and an attachment mechanism for attaching the valve to the superior rim of the valve cage stent. The valve can be of a bi-leaflet or a tri-leaflet type and includes a valve frame made from a memory metal and a tissue cover attached to the valve frame. The valve cage stent is self-expanding or balloon expandable, made respectively from memory metal or stainless steel but otherwise structurally the same.
