Method and apparatus for monitoring an organ of a patient

An implanted device for an organ of a patient including a housing. The device includes a detector having electrodes that have a varying distance over time between them which produces a detector signal based on electrical signals derived from the organ. The device includes a signal processor disposed in the housing in communication with the detector which determines admittance from the detector signal based on the varying distance over time between the electrodes. The device includes a drive circuit disposed in the housing to cause the electrodes to generate emitted electrical signals.

Medical device identifier

A medical device identifier can identify an implanted medical device. In one example arrangement, the medical device identifier sends electromagnetic signals to the implanted device according to one or more stored digitized waveforms. The device then senses any returned electromagnetic signals, and identifies the implanted device based on the returned electromagnetic signals. The medical device identifier may generate the electromagnetic signals from the stored digitized waveforms using an analog-to-digital converter, and may compare the returned electromagnetic signals with one or more stored digital templates corresponding to different device manufacturers. The comparison may be performed using cross correlation. In another aspect, a portal device includes an identification subsystem for identifying the provider of a medical device, and a communication subsystem for establishing two-way communication a call center servicing medical devices from an identified provider. The portal device may relay information between the medical device and the identified provider.Board of Regents, University of Texas Syste
