Power saving communication method for an implantable medical device
First Claim
1. A communication control method comprising:
- determining a size of a data packet received from an implantable medical device or transmitted to the implantable medical device;
setting a timer to a value defined based on the size;
selectively controlling the generation of power down requests defining a power down of at least one of a transmitter and a receiver of the implantable medical device based on a current value of the time;
wherein the setting comprises;
setting the timer to a first predetermined value if the size exceeds a threshold size; and
setting the timer to a second predetermined value if the size is below the threshold size, the first predetermined value being larger than the second predetermined value; and
based on the received or transmitted data packet, having the implantable medical device provide therapy to a patient.

Abstract
A non-implantable communication unit conducts wireless communication with an implantable medical device (IMD). The communication unit comprises a request processor for generating power down requests destined to the IMD and triggering temporary power down of the IMD radio equipment. When the communication unit receives a data packet from the IMD or a connected programmer it determines the size of the data packet. A timer processor sets a timer to a value defined based on the determined size. A processor controller selectively controls the operation of request processor to generate or stop generating the power down requests based on a current value of the timer. Power down of the IMD radio equipment is thereby prevented if it is likely that the IMD comprises data to transmit to the communication unit as predicted based on data packet sizes.
