INITIATING MEDICAL SYSTEM COMMUNICATIONS
First Claim
Patent Images
1. A method for initiating communications with a medical device, the method comprising:
- bringing a signal source into contact with a body;
transmitting an oscillatory signal through the body, in which the medical device is implanted, from the signal source to a transducer being coupled to an RF telemetry component of the medical device;
detecting a response of the transducer to the signal; and
activating the RF telemetry component upon detection of the response in order to initiate communications.

Abstract
A medical system includes a body-contacting signal source adapted to transmit an oscillatory signal though a body to a transducer of a device implanted therein. A detector that is coupled to the transducer, upon detection of a response of the transducer to the signal, activates a radio-frequency (RF) telemetry component of the device.

8. A medical system, comprising:
-
at least one implantable device including an RF telemetry component coupled to a signal detector, and a signal transducer coupled to the signal detector, the signal detector controlling activation of the RF telemetry component;
a body-contacting signal source adapted to transmit an oscillatory signal through a body to the transducer of the device, when the device is implanted in the body;
the signal detector, upon detection of a response of the transducer to the signal, activating the RF telemetry component to initiate communications with the implanted device. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. An implantable medical device, comprising:
-
a communications module for RF telemetry, the module including a telemetry component being one of a receiver, a transmitter, and a transceiver; and
an acoustic transducer coupled to a detector, the detector coupled to the telemetry component, the detector being adapted to activate the telemetry component upon detection of a response of the transducer to an acoustic activation signal.
