Low power advertisement schedule for implantable medical device and method
First Claim
1. A method of operating an implantable medical device (IMD) for conducting communications, after implantation within a patient, with a device external to the patient, the method comprising:
- operating wireless communication circuitry of the IMD to provide advertising notices according to a wireless communication protocol for establishment of one or more wireless communication sessions between the IMD and the device external to the patient, wherein (1) the operating comprising providing advertising notices according to first and second connection schemes, (2) the first connection scheme provides advertising notices according to a first frequency and the second connection scheme provides advertising notices according to a second frequency, (3) the first frequency is greater than the second frequency to provide lesser connection latency according to the first connection scheme compared to connection latency of the second connection scheme, (4) the operating provides advertising notices according to the first connection scheme at a lower transmit power than advertising notices according to the second connection scheme, and (5) the operating employs the first and second connection schemes for providing advertising notices according to a schedule;
receiving a request from the device external to the patient to establish a communication session with the IMD in response to device external to the patient receiving an advertising notice from the IMD;
establishing a communication session with the device external to the patient to communicate IMD data with the device external to the patient; and
communication IMD data with the device external to the patient.

Abstract
Methods and devices are provided for managing establishment of a communications link between an external instrument (EI) and an implantable medical device (IMD). The method stores, in the IMD, an advertisement schedule that includes first and second power schemes to be utilized with advertisement notices. The first and second power schemes define at least one of i) first and second power levels for transmitting the advertisement notices or ii) first and second receive sensitivities to scan for a connection request. The method manages at least one of a transmit or receive operation of the IMD, utilizing the first and second power schemes in connection with first and second advertisement notices, respectively. The method establishes a communication session between the IMD and the EI.
