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.

La présente invention concerne un ensemble pompe intravasculaire et cathéter à ballonnet. Ledit ensemble comprend un cathéter principal muni d'un ballon placé sur le cathéter et d'une pompe intravasculaire placée à l'intérieur du cathéter. La pompe est destinée à créer une différence de pression entre l'orifice d'entrée du cathéter et l'orifice de sortie. Cette structure permet de délivrer, sous pression, un liquide aux différentes canules d'artériotomie placées à l'extrémité de l'ensemble. Les canules sont insérées dans les vaisseaux sanguins en des endroits appropriés de manière à permettre de contourner une obstruction ou un rétrécissement du vaisseau sanguin tout en maintenant le flux sanguin dans le corps.
