Abstract
A medical implant system comprises an implant proportioned for implantation within a blood vessel, a lead coupled to the implant, and an anchor coupled to the lead, the anchor configurable in a radially compressed position so as to be positioned in the blood vessel, and a radially expanded position for engagement with the wall of blood vessel. The anchor functions as an antenna for telemetric communication with an extracorporeal device and/or as a receiver for inductive recharging of secondary cells in the implant using an extracorporeal charging device.

A medical implant system comprising:
- an implant proportioned for implantation within a blood vessel;
- a lead coupled to the implant;
- and
- an anchor coupled to the lead, the anchor configurable in a radially compressed position so as to be positioned in the blood vessel, and configurable in a radially expanded position to retain the anchor within the blood vessel;
- and
- a coil on the anchor;
- and
- an extracorporeal device including a primary coil energizable to create an electromagnetic field that in turn induces current in the coil on the anchor.

A method of recharging a medical implant, comprising the steps of
- positioning a medical implant within a living body, the medical implant including a housing containing a battery and a lead extending from the housing;
- anchoring the lead in a blood vessel of the patient using an expandable anchor having a coil thereon;
- positioning an extracorporeal charging device in proximity to the blood vessel containing the lead, the charging device including a primary coil;
- and
- energizing the primary coil to create an electromagnetic field that in turn induces current in the coil on the anchor.
