left ventricle valve mount 154 is proximally adjacent to tapered tip 144 and can carry the self expanding prosthetic valve payload alternatively valve mount 154 can be replaced by an assembly of an inflatable balloon not shown surrounded by a stented valve with the balloon later inflated to expand the valve to its final set diameter in fig1 a preferred implantation process of a stented valve 160 mounted on an inflation balloon 162 which is part of a delivery system is illustrated in one advantageous feature a bendable i e flexible pusher member 164 pushes directly on the stented valve 160 although pusher member is bendable pusher member is substantially rigid along its longitudinal axis for transmitting longitudinal forces to the stented valve the absence of the pusher member would require pushing the stented valve over a guidewire 166 via the catheter shaft 168 the shaft has much less rigidity and pushing force than the pusher and in many cases would become twisted and in some cases kinked disabling the delivery of the valve to the desired location in stenotic valves the case is even worse since passing a stenotic valve 170 to place the prosthetic valve is very difficult and requires significant pushing forces the pusher member described here enables one to achieve effective pushing forces all the way to the stenotic valve and across it with reference to fig1 to 23 preferred.
