ALERTING METHOD FOR A TRANSVASCULAR TISSUE STIMULATION SYSTEM
First Claim
1. A medical apparatus for therapeutically treating a patient, said medical apparatus comprising:
- a medical device for implantation entirely in vasculature of the patient and having a discriminator that receives and extracts energy from a first wireless signal which energy is used to power the medical device, a detector circuit that senses at least one of a physiological characteristic and performance of the medical device and in response produces data, and a feedback transmitter that sends information related to the data via a second wireless signal; and
an external power source, that is outside the patient and which transmits the first wireless signal, the external power source having a receiver that receives the second wireless signal and extracts the information, and a communication module with cellular telephone circuitry;
wherein when the information indicates existence of a predefined condition, the communication module dials a predefined telephone number assigned to a remote monitor and sends an alert message for reception by the remote monitor.

Abstract
A system for stimulating tissue of the patient includes an implantable medical device and an external power source. The medical device receives and extracts electrical energy from a first wireless signal and has a detector circuit that senses a physiological characteristic of the patient. The sensing can occur simultaneously while electrical stimulation pulses are applied to the tissue. A feedback transmitter that sends information related to the physiological characteristic via a second wireless signal. The external power source transmits the first wireless signal and extracts the information from a second wireless signal. When the information indicates existence of a predefined condition, a communication module, that preferably includes a cellular telephone sends a message for reception by the remote monitor to alert medical personnel.

15. A medical apparatus that monitors a medical patient and stimulates tissue of the medical patient, said medical device comprising:
-
a medical device for implantation entirely in vasculature of the patient and having a discriminator that receives and extracts energy from a first wireless signal which energy is used to power the medical device, a pair of electrodes for contacting the tissue, a stimulation circuit that applies electrical stimulation pulses to the pair of electrodes, a detector circuit connected to the pair of electrodes to sense a physiological characteristic of the medical patient simultaneously when one of the electrical stimulation pulses is being applied to the pair of electrodes and produce data from such sensing, and a feedback transmitter that sends the data via a second wireless signal; and
an external power source that is outside the patient and which transmits the first wireless signal, the external power source having a receiver that extracts the data from the second wireless signal, and having an implant monitor which processes the data and provides an indication when the data indicates existence of a predefined condition, and a communication module that responds to the indication by sending a third wireless signal. - View Dependent Claims (16, 17, 18, 19, 20, 21)
