Abstract
An intravascular pump and balloon catheter assembly is shown. The assembly includes a primary catheter having a balloon provided thereon and an intravascular pump provided therein. The pump is adapted to generate a pressure differential between the inlet of the catheter and the outlet. With this structure, fluid is supplied, under pressure, to multiple arteriotomy cannulae provided at the terminal end of the assembly. The cannulae are inserted into blood vessels at appropriate points so that an occlusion or restriction in a blood vessel can be bypassed while still maintaining blood flow throughout the body.
