While implantable heart pumps may buy some time for people waiting to undergo heart transplants, such implants have at least one serious drawback – because they receive their power from an external source, a power cord must protrude through the skin of the patient’s belly. About 40 percent of patients experience infections of that opening, which often require rehospitalization, and in extreme cases can even cause death. The presence of that cord also makes it impossible for patients to swim or take baths. Researchers from the University of Washington and the University of Pittsburgh Medical Center are attempting to put an end to the troublesome cords, however, by developing a system that wirelessly transmits power to heart pumps.
