摘要：
An implantable microstimulator (10) configured to be implanted for tissuestimulation employs a self-contained power source (16) and a bi-directional RFtelemetry link (48) for allowing data-containing signals to be sent to andfrom the implantable microstimulator (10) from at least two external devices(39, 40). Further, a separate electromagnetic inductive telemetry link (38)allows data containing signals to be sent to the implantable microstimulatorfrom at least one of the two external devices (39). The RF bidirectionaltelemetry link (48) allows the microstimulator to inform the patient orclinician regarding the status of the microstimulator device, including thecharge level of a power source, and stimulation parameter states. Themicrostimulator has a cylindrical hermetically sealed case (12) having alength no greater than about 27 mm and a diameter no greater than about 3.3mm. A reference electrode (22) is located on one end of the case and an activeelectrode (24) is located on the other end of the case.
