Secure long-range telemetry for implantable medical device
First Claim
1. A method for implementing communications between an implantable medical device (IMD) and an external device (ED) over a telemetry channel, comprising:
- limiting data communications between the IMD and ED over the telemetry channel with a telemetry interlock has been released, wherein the telemetry interlock is released when the IMD receives an enable command via a short-range communications channel requiring physical proximity to the IMD; and
, allowing communication over the telemetry channel between the IMD and the ED but preventing programming of the IMD over the telemetry channel if the telemetry interlock is not released.

Abstract
A method and system for enabling secure communications between an implantable medical device (IMD) and an external device (ED) over a telemetry channel. A telemetry interlock may be implemented which limits any communications between the ED and the IMD over the telemetry channel, where the telemetry interlock is released when the ED transmits an enable command to the IMD via a short-range communications channel requiring physical proximity to the IMD. As either an alternative or addition to the telemetry interlock, a data communications session between the IMD and ED over the telemetry channel may be allowed to occur only after the IMD and ED have been cryptographically authenticated to one other.
