Abstract
A high pressure inflation system for driving an inflatable heart assistance device. The system includes a fluid source for supplying a fluid at a relatively high pressure and a compression tank plumbed in selective communication with the pneumatic source. The compression tank is operative to store a predetermined volume of the pressurized fluid at approximately the high pressure created by the fluid source. A transfer valve is disposed downstream of the compression tank and is coupled to the heart assistance device. The compression tank and transfer valve are maintained in close proximal relation to the heart assistance device with the transfer valve being responsive to predetermined signals to expose the heart assistance device to the compression tank pressure and expand the device to compress and assist the heart.
