Centrifugal Blood Pump With Partitioned Implantable Device

摘要

A centrifugal blood pump system has a self-contained pumping unit and a self-contained motor unit. A pump outlet extends radially from a pump housing of the pumping unit. A percutaneous cable passes through a radial exit from a motor housing of the motor unit. The motor housing has a substantially planar face configured to mate with a substantially planar face of the pump housing. The pumping unit and the motor unit are configured to latch together in a plurality of orientations, each orientation having the substantially planar faces mated and the outlet and radial exit at a different respective angular separation. The pumping unit and the motor unit are configured such that after the pumping unit is implanted, the motor unit can be unlatched and a replacement motor unit latched with the pumping unit at the plurality of orientations.
