Abstract
A frame system for heart valve prosthesis. A first frame has at least three generally parallel legs each comprising a pair of rod portions connected at one end and diverging at the other end as lobes respectively connecting with rod portions of others of said legs. The lobes form an aperture therebetween and the legs are adapted to receive the margin of a valve leaflet between the rod portions thereof. Thus, the leaflet may be secured to two adjacent legs and the interconnecting lobe so as to have a free edge extending between said adjacent legs. A second frame is adapted to nest with the first frame and comprises a rod formed to be substantially congruent with the interconnecting lobes, whereby the leaflets may be secured to and between the frames.
