1. A system, comprising:
- an implantable medical device including;
a therapy module; and
an implant telemetry module; and
an external system, including;
a programming module; and
an external telemetry module,wherein the implant telemetry module and the external telemetry module each include a telemetry circuit including;
an antenna;
a transceiver coupled to the antenna, the transceiver adapted to transmit over a plurality of channels each representing a predetermined frequency band for data transmission between the implantable medical device and the external system; and
a telemetry controller coupled to the transceiver, the telemetry controller adapted to control a channel hopping process including detecting an interruption of communication on a first frequency, scanning a subset of available communication frequencies for a response from the implantable medical device, and resuming communication with the implantable medical device after receiving a response, on a second frequency on which the response was received.

Abstract
A telemetry system for data transmission between an implantable medical device and an external system includes a plurality of channels each representing a frequency band within a predetermined frequency range. The data transmission is performed using at least one active channel at any instant. Channel hopping is performed upon detecting an interruption of communication, such that a scan is performed through an array of channels selected from the plurality of channels. If a data frame is not successfully transmitted, it is repeatedly re-transmitted using the current and/or the next active channels until its transmission becomes successful.
