Abstract:
1. A cardiovascular prosthetic valve comprising: a stentless support structure, the stentless support structure comprising an inflatable cuff comprising at least one inflatable channel that forms, at least in part, a distal inflatable toroidal structure and a proximal inflatable toroidal structure, the inflatable cuff also comprising a waist that extends between the distal inflatable toroidal structure and the proximal inflatable toroidal structure, wherein the inflatable cuff is transformable from a reduced cross sectional configuration for transluminal deployment to a functional enlarged configuration to form a flow path through the support structure; a valve coupled to the inflatable cuff and positioned in the flow path, the valve configured to permit flow in a first axial direction and to inhibit flow in a second axial direction opposite to the first axial direction; a hardenable media positioned within the inflatable cuff holding the inflatable cuff in the functional enlarged configuration; and wherein the inflatable cuff in the functional enlarged configuration exhibits sufficient crush resistance that it will deform radially no more than about 0.3 inches under a load of about 4 pounds when the hardenable media in the inflatable cuff is hardened.
