During the implantation procedure, which is similar to implanting a pacemaker, physicians tested the device to ensure that the patient's heart responded to the special signals the device delivered. Two patients did not respond, so the device was not implanted. In the othe...Mayo Clinic finds weight not a factor among women using fertility technologies to become pregnant
