COMMUNICATION BETWEEN EXTERNAL DEVICES AND IMPLANTABLE MEDICAL DEVICES
First Claim
Patent Images
1. A method comprising:
- sensing, with a sensor of an implantable medical device (IMD), a first signal that includes a communication key;
receiving, with the IMD, the communication key from the sensed first signal;
coding, with the IMD, at least one of a second signal transmitted by the IMD and a second signal received by the IMD with the communication key received from the sensor; and
sensing, with the sensor that sensed the first signal, a patient characteristic.

Abstract
In general, the techniques of this disclosure are directed to communication between an implantable medical device (IMD) and an external device. In some examples, the external device transmits a signal that includes a communication key. One or more sensors of the IMD sense the signal that includes the communication key, and the IMD uses the communication key for coding the communication between the IMD and the external device. The one or more sensors that sensed the signal may also sense one or more patient characteristics.
