EXTERNAL UNIT FOR IMPLANTABLE MEDICAL DEVICE COUPLED BY CORD
First Claim
1. An implantable medical device system, comprising:
- an implantable medical device for providing a therapeutic output to a patient, said implantable medical device being configured to inductively couple energy with a secondary coil and configured to be transcutaneously controlled using an internal telemetry coil; and
an external antenna having a primary coil configured to inductively transfer energy to said secondary coil of said implantable medical device when said external antenna is externally placed in proximity of said secondary coil;
an external unit configured to be operatively coupled by a cord to said external antenna to inductively transfer energy to said implantable medical device;
said external unit having an external telemetry coil allowing said external unit to communicate with said implantable medical device through said internal telemetry coil in order to at least partially control said therapeutic output of said implantable medical device while transferring energy to said implantable medical device using said primary coil of said antenna.

Abstract
User interface for external power source, recharger, for an implantable medical device. At least some of patient controls and display icons of an energy transfer unit are common with at least some of the patient controls and the display icons of a patient control unit. An energy transfer unit is operable by the patient with less than three operative controls to control energy transfer from the external energy transfer unit to the implantable medical device. An external antenna having a primary coil can inductively transfer energy to a secondary coil of the implantable medical device when the external antenna is externally placed in proximity of the secondary coil. An energy transfer unit has an external telemetry coil allowing the energy transfer unit to communicate with the implantable medical device through the internal telemetry coil in order to at least partially control the therapeutic output of the implantable medical device.

29. A method of controlling an implantable medical device for providing a therapeutic output, said implantable medical device capable of receiving inductively coupled energy with a secondary coil and being capable of being transcutaneously controlled using an internal telemetry coil, comprising the steps of:
-
inductively transferring energy to said secondary coil with an external antenna having a primary coil when said external antenna is externally placed in proximity of said secondary coil; driving said primary coil with an external unit operatively coupled by a cord to said external antenna to inductively transfer energy to said implantable medical device; and communicating, simultaneous with said inductively transferring step, with an external telemetry coil in said external unit with said implantable medical device through said internal telemetry coil in order to at least partially control said therapeutic output of said implantable medical device. - View Dependent Claims (30, 31, 32, 34, 35, 36, 37, 38, 39, 40, 41, 42)
