Variable implantable medical device power characteristics based upon data or device type
First Claim
1. An implantable medical device (“
- IMD”
) comprising;
power scaling logic configured to process information pertaining to a telemetry communication device external to the IMD, and configured to generate scaling instructions in response to the information; and
a transmitter coupled to the power scaling logic and configured to transmit telemetry signals, the transmitter having variable power characteristics;
whereinthe scaling instructions adjust the variable power characteristics of the transmitter.

Abstract
An implantable medical device (“IMD”) as described herein includes adjustable power characteristics such as variable transmitter output power and variable receiver front end gain. These power characteristics can be adjusted in a dynamic manner based upon various operating aspects of the intended or actual IMD telemetry environment. These operating aspects may include the external telemetry device type, the IMD device type, and/or the type, context, or meaning of the telemetry data transmitted by the IMD. The IMD may process information related to these operating aspects to generate power scaling instructions or control signals that are interpreted by the IMD transmitter and/or the IMD receiver. Such adjustability enables the IMD to satisfy minimum telemetry requirements in a manner that does not waste power, thus extending the IMD battery life.
