IMPLANTABLE MEDICAL DEVICE WITH A TETHERED TRANSMIT COIL FOR TRANSMITTING POWER TO ANOTHER IMPLANTABLE MEDICAL DEVICE

摘要

A system for sensing electrical cardiac activity and for providing therapy to a patient's heart. The system may include a first implantable device implanted within a patient and a second implantable device implanted near or within the heart of the patient. In some cases, the first implantable device may at least partially power the second implantable device by periodically recharging a rechargeable battery or other power source within the second implantable device. In some cases, the first implantable device may at least partially power the second implantable device by periodically, intermittently or continuously transmitting energy that may be stored by a battery, capacitor or other power storage device within the second implantable device.
