SYSTEM AND METHODS FOR ESTABLISHING A COMMUNICATION SESSION BETWEEN AN IMPLANTABLE MEDICAL DEVICE AND AN EXTERNAL DEVICE

摘要

A method is provided for establishing a communication session with an implantable medical device (“IMD”). The method includes configuring an IMD and an external device to communicate with one another through a protocol that utilizes a dedicated advertisement channel. The IMD periodically transmitting advertisement notices over the dedicated advertisement channel according to the protocol. The advertisement notices being transmitted periodically at an advertisement period over multiple cycles. The method further includes repeatedly scanning the advertisement channel, by the external device, for select scanning intervals in search of the advertisement notices, the scanning operation being repeated periodically at a scan period over the multiple cycles. The advertisement period and the scan period are independent of one another such that the advertisement and scan periods at least partially overlap intermittently after a number of cycles. When the external device detects one of the advertisement notices, the method includes establishing a communications link between the external device and the IMD.

1. A method for establishing a communications session with an implantable medical device (IMD), the method comprising:
configuring an IMD and an external device to communicate with one another through a protocol that utilizes a dedicated advertisement channel; periodically transmitting, from the IMD, advertisement notices over the dedicated advertisement channel according to the protocol, the advertisement notices being transmitted periodically at an advertisement period over multiple cycles; repeatedly scanning the advertisement channel, by the external device, for select scanning intervals in search of the advertisement notices, the scanning operation being repeated periodically at a scan period over multiple cycles, wherein the advertisement period and scan period are independent of one another such that the advertisement and scan periods at least partially overlap intermittently after a number of cycles; and when the external device detects one of the advertisement notices, establishing a communications link between the external device and the IMD.
