This power cable literally serves as a lifeline for patients with advanced heart failure. It is a key part of the Heartmate II (Registered) system, Thoratec’s breakthrough left ventricular assist device that gives heart failure patients a new lease on life. The unique core mold and strain relief design insure durability and reliability with required holding tolerances to as tight as +/- .005”. The cable supplies power from either DC battery clips or AC patient cables to the controller. The cables are built by DC Electronics.
