Abstract
A high efficiency cardiac support system is suitable for chronic use in treating heart failure, wherein the system includes an implantable rotary blood pump, an implantable power module, a wireless power transfer subsystem, a patient monitor, and a programmer. In a cardiac support system, the cumulative efficiencies of the components of the system are capable of providing therapeutically effective blood flow for a typical day of awake hours using the energy from a single wireless recharge of an implanted rechargeable energy source. Moreover, the implantable rechargeable energy source may be recharged during a normal sleep period of 8 hours or less. The system may provide full or partial cardiac support without the need for external wearable batteries, controllers, or cables.
