Far field telemetry operations between an external device and an implantable medical device during recharge of the implantable medical device via a proximity coupling
First Claim
1. A method of recharging an implantable medical device, comprising:
- establishing a far field telemetry communication session with the implantable medical device;
transferring power over a proximity coupling to the implantable medical device during the far field telemetry communication session;
receiving recharge information from the implantable medical device via the far field telemetry communication session while transferring power to the implantable medical device; and
after receiving the recharge information, suspending the far field telemetry communication session for a period of time while transferring power to the implantable medical device.

Abstract
Far field telemetry operations are conducted between an external device and an implantable medical device while power is being transferred to the implantable medical device for purposes of recharging a battery of the implantable medical device. The far field operations may include exchanging recharge information that has been collected by the implantable medical device which allows the external device to exercise control over the recharge process. The far field operations may include suspending far field telemetry communications for periods of time while power continues to be transferred where suspending far field telemetry communications may include powering down far field telemetry communication circuits of the implantable medical device for periods of time which may conserve energy. The far field operations may further include transferring programming instructions to the implantable medical device.

15. A medical system, comprising:
-
an external device having a far field telemetry communication circuit and a recharge circuit, the external device transferring power through a recharge head of the recharge circuit while receiving recharge information through a far field telemetry communication session via the far field telemetry communication circuit, the external device suspending the far field telemetry communication session for a first period of time after receiving the recharge information by sending an instruction to close the far field telemetry communication session to the implantable medical device while continuing to transfer power; and an implantable medical device having a far field telemetry communication circuit and a recharge circuit, the implantable medical device receiving transferred power via a proximity coupling of the recharge circuit to the recharge head of the external device while sending recharge information through the far field telemetry communication session via the far field telemetry communication circuit, the implantable medical device closing the far field telemetry communication session upon receiving the instruction. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. An implantable medical device, comprising:
-
a medical circuit that performs a medical task; a battery that provides power to the medical circuit; a recharge circuit that provides power to the battery; a far field telemetry communication circuit; and a processor that controls the recharge circuit and the far field telemetry communication circuit, the processor directing the recharge circuit to receive transferred power from a proximity coupling to a recharge head of an external device, the processor directing the far field telemetry communication circuit to send recharge information via a far field telemetry communication session with the external device while the recharge circuit receives transferred power, the processor further directing the far field telemetry communication circuit to power down in response to receiving a command to close the communication session with the external device while the recharge circuit receives transferred power, and the processor periodically directing the far field telemetry communication circuit to power up while the recharge circuit receives transferred power.
