Telemetry system for use with microstimulator
First Claim
1. A neurostimulator system, comprising:
- a first external device;
a second external device; and
an implantable stimulator having an antenna, wherein the implantable stimulator is configured to generate stimulation pulses in accordance with programmed parameters,wherein the first external device is configured to communicate data with the antenna in the implantable stimulator in accordance with a first modulation scheme via a first telemetry link,wherein the second external device is configured to communicate data with the antenna in the implantable stimulator in accordance with at least a second modulation scheme different from the first modulation scheme via a second telemetry link, andwherein the implantable stimulator is configured to use the second telemetry link to provide power to the implantable stimulator.

Abstract
An implantable microstimulator configured to be implanted beneath a patient'"'"'s skin for tissue stimulation employs a bi-directional RF telemetry link for allowing data-containing signals to be sent to and from the implantable microstimulator from at least two external devices. Further, a separate electromagnetic inductive telemetry link allows data containing signals to be sent to the implantable microstimulator from at least one of the two external devices. The RF bidirectional telemetry link allows the microstimulator to inform the patient or clinician regarding the status of the microstimulator device, including the charge level of a power source, and stimulation parameter states. The microstimulator has a cylindrical hermetically sealed case having a length no greater than about 27 mm and a diameter no greater than about 3.3 mm. A reference electrode is located on one end of the case and an active electrode is located on the other end of the case.
