Congestive heart failure (CHF) is a debilitating condition that afflicts 4.8 million Americans with an increasing incidence. Each year, there are an estimated 400,000 new cases. The incidence is on the rise as the age of the population is increasing and because most people are surviving their first heart attack. Pharmacological therapies are improving, yet many patients still reach end-stage heart failure and there are too few donor hearts available. This thesis is presented as a first small step in a long process in the design and development of a novel cardiac assist device that would ultimately heal a diseased heart by the process of ventricular recovery. The device acts to restore the kinematics of a diseased heart by modulating the extra ventricular displacements. The first surgery / trial were conducted on a bovine at the Veterinary School at Texas A&M University. Main objectives of the surgery were to test the method of attachment of the device and power requirements of the device. Details regarding the design and construction of the device have been presented in the thesis.
