Telemetry-based wake up of an implantable medical device
First Claim
1. A method for handling a wake-up signal at an implantable medical device, the wake-up signal being broadcast from an external component wishing to communicate with the implantable medical device, the wake-up signal comprising a plurality of sequential bits, the method comprising:
- powering a receiving circuit in the implantable medical device which receives the wake-up signal;
receiving a first potion of the wake-up signal at the implantable medical device;
assessing the validity of the received first portion at the implantable medical device;
if the received first portion is assessed as valid, continuing to power the receiver circuit to receive at least a second portion of the wake-up signal at the implantable medical device; and
if the received first portion is assessed as not valid, powering off the receiver circuit.

Abstract
A method for telemetry between an implantable medical device and an external programming component is disclosed. The telemetry circuitry of the implantable device is initially powered on for only a portion of the time needed to receive the entirety of a wake-up signal from the external component. During that time, only a first portion of the wake-up signal as received form the external component is checked against the implantable device'"'"'s understanding of that first portion as stored in its memory. If the implantable device does not recognize the received first portion, powering on of the telemetry circuitry is terminated. However, if that first portion is recognized, then the implantable device continues to power on the telemetry circuitry to receive another (second) portion of the wake-up signal. If that received second portion is recognized, then the telemetry circuitry is further powered to receive a next (third) portion of the wake-up signal from the external component, etc., until the entirety of the wake-up signal is recognized by the implantable device as having been received.

16. A method for controlling a medical device implanted in a patient, the wake-up signal being broadcast from an external component external to the patient, the wake-up signal comprising a plurality of sequential bits, the method comprising:
-
wirelessly broadcasting a wake-up signal from the external component;
periodically powering a receiving circuit in the implanted medical device to receive the wake-up signal;
receiving a first potion of the wake-up signal at the implanted medical device while the receiving circuit is powered, wherein the received first portion comprises a plurality of the sequential bits of the wake-up signal;
assessing the validity of the received first portion at the implanted medical device;
if the received first portion is assessed as valid, continuing to power the receiver circuit to receive at least a second portion of the wake-up signal at the implanted medical device, wherein the received second portion comprises a plurality of the sequential bits of the wake-up signal; and
if the received first portion is assessed as not valid, powering off the receiver circuit until the next period. - View Dependent Claims (17, 18, 19, 20, 21)
