  • Heart pump
    Patent number: 4493314
    Abstract: A pulsatible outflow, continuous and non-sucking inflow, artificial heart pump utilizes a pump body in which the ends of a pair of passages open at two spaced locations on the body. One of the passages permits only outflow, and the other permits only inflow; the commonly located ends thereof communicate with one another through passively distensible sacs. Discharge of the sacs is achieved with reciprocating pistons, the stroke and timing of which are controlled by a motor-drived cam ring disposed about the pistons and the pump body.
