Abstract
A mechanical device for implantation into a patient's body is designed or modified to be electrically charged to prevent coagulation on the device, thereby extending the life of the device and alleviating the need for the patient to utilize anticoagulant therapy. The device may be a heart valve and is electrically charged by being connected to a power source. The power source is preferably a battery pack implanted in the body and is connected to the device by connector wires. The charge applied to the device may be negative or positive, as long as it helps to repel platelets and/or red blood cells from the device in order to help prevent coagulation on one or more surfaces of the device.
