Abstract
A mechanical circulatory support device is provided. The device has a housing containing separate first and second pumps. Each pump having an inlet, an outlet, and an impeller. The device also having a switching mechanism located within the housing and movable from a first position to a second position to divert blood flow within the housing to an inlet of one of the pumps and/or to bypass blood flow relative to one of the pumps within the housing.
Claims16
A mechanical circulatory support device, comprising:
- a housing containing separate first and second pumps, each pump having an inlet, an outlet, and an impeller;
- and
- a switching mechanism within said housing and movable from a first position to a second position to divert blood flow within said housing to one of said pumps or to bypass blood flow relative to one of the pumps within the housing;
- wherein, in the first position, the switching mechanism directs blood flow through the first pump and not the second pump, and wherein, in the second position, the switching mechanism directs blood flow through the second pump and not the first pump;
- and
- wherein the first and second pumps include a centrifugal pump and an axial flow pump.
