First Claim
Patent Images
1. A method of power transmission control by an active implantable medical device, the method comprising:
- establishing a communications link with an external data retrieval apparatus during a portion of a period of time, wherein the portion corresponds to a time during which a measure of quality of a signal transmitted by the active implantable medical device and received by the external apparatus has previously satisfied a criterion value;
transmitting data to the external data retrieval apparatus during the portion of the period of time; and
controlling a signal transmission power level of the implantable medical device during the portion of the period of time by;
receiving a current measure of quality of a signal transmitted by the active implantable medical device, the current measure received from the external data retrieval apparatus;
comparing the current measure to the criterion value; and
adjusting the signal transmission power level until the current measure is at or near the criterion value.

Abstract
An external data retrieval apparatus includes a transceiver, and a processing system coupled to the transceiver. The processing system obtains a plurality of measures over a period of time. The measures relate to a quality of a communications channel between the data retrieval apparatus and an active implantable medical device. The processing system determines a trend in the plurality of measures over the period of time, and then determines a preferred time during which to retrieve data based on the trend.

9. An active implantable medical device, comprising:
-
a transceiver configured to; establish a communications link with an external data retrieval apparatus during a portion of a period of time, wherein the portion corresponds to a time during which a measure of quality of a signal transmitted by the active implantable medical device and received by the external apparatus has previously satisfied a criterion value; transmit data to the external data retrieval apparatus during the portion of the period of time; and a processing system coupled to the transceiver and configured to control a signal transmission power level of the implantable medical device during the portion of the period of time by being further configured to; receive a current measure of quality of a signal transmitted by the active implantable medical device, the current measure received from the external data retrieval apparatus; compare the current measure to the criterion value; and adjust the signal transmission power level until the current measure is at or near the criterion value. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
