WAKEUP OF IMPLANTABLE COMMUNICATION CIRCUITRY
First Claim
1. A communication device configured to conduct wireless radio frequency, RF, based communication with an implantable medical device, comprising:
- a transmitter connected to an RF antenna;
a receiver connected to an RF antenna;
a wakeup processor connected to said transmitter and configured to generate wakeup messages, said wakeup processor being configured to generate first wakeup messages comprising a first identifier code associated with said implantable medical device and second wakeup messages comprising a second identifier code associated with said implantable medical device, and said transmitter being configured to transmit said first wakeup messages and transmit said second wakeup messages.

Abstract
An IMD has its communication circuitry in an inactive state and has access to two different identifier codes. The IMD activates the communication circuitry based on reception of a wakeup message that includes an identifier code that is identical to the identifier code currently assigned to the IMD. A communication device generates and transmits first wakeup messages that include a first identifier code associated with the IMD and second wakeup messages that include a second identifier code associated with the IMD. Depending on the currently assigned identifier code of the IMD the IMD will respond to either first or second wakeup messages.

21. A method of waking up an implantable medical device comprising:
-
receiving a wakeup message comprising an identifier code; comparing said identifier code to an identifier code currently assigned to said implantable medical device; and switching a transmitter of said implantable medical device from an inactive state to an active state if said identifier code comprised in said wakeup message is equal to said identifier code currently assigned to said implantable medical device, and selecting one of a first identifier code and a second identifier code as said identifier code currently assigned to said implantable medical device. - View Dependent Claims (22, 23, 24, 25, 26, 27)
