摘要： A system for percutaneously inserting a prosthesis containing a biological replacement for a defective valve into an implantation site through a body lumen. The system contains a balloon catheter upon which a collapsable stent containing a venous valvular replacement is mounted. A protective shield is slidably mounted upon the catheter that is movable between a closed position over the balloon and an open position wherein the balloon can be inflated to expand the stent. A central lumen runs through the catheter that is formed of stainless steel. The central lumen provides a one to one torque ratio between the proximal end of the catheter and the distal end to enhance the steerability of the catheter. The vein of the replacement is reduced in thickness between 50% and 90% of its original size thereby considerably reducing the size of the replacement package when the stem is collapsed upon the balloon of the catheter.

摘要： A replacement prosthetic heart valve for engagement with a structure of a previously implanted prosthetic heart valve. The replacement heart valve includes a stent structure including a generally tubular body portion with an interior area and a series of wire portions arranged in a mesh-like configuration, and at least one stent post engaging structure extending radially outwardly from the body portion for engaging with an outer surface of a stent post of the previously implanted prosthetic heart valve. The stent structure further includes at least two leaflets attached within the interior area of the tubular body portion of the stent structure.

摘要： A heart valve that can be expanded following its implantation in a patient, such as to accommodate the growth of a patient and the corresponding growth of the area where the valve is implanted, and to minimize paravalvular leakage. In one aspect, the invention may maximize the orifice size of the surgical valve. The invention includes expandable implantable conduits and expandable bioprosthetic stented valves. In one aspect of the invention, the valve may be adapted to accommodate growth of a patient to address limitation on bioprosthetic valve lifespans.
