Patent number: 12284699Abstract: A method and device for managing establishment of a communications link between an external instrument (EI) and an implantable medical device (IMD) are provided. The method stores, in a memory in at least one of the IMD or the EI, a base scanning schedule that defines a pattern for scanning windows over a scanning state. The method enters the scanning state during which a receiver scans for advertisement notices during the scanning windows. At least a portion of the scanning windows are grouped in a first segment of the scanning state. The method stores, in the memory, a scan reset pattern for restarting the scanning state. Further, the method automatically restarts the scanning state based on the scan reset pattern to form a pseudo-scanning schedule that differs from the base scanning schedule and establishes a communication session between the IMD and the EI.Type: GrantFiled: November 28, 2023Date of Patent: April 22, 2025Assignee: Pacesetter, Inc.Inventors: Yongjian Wu, Jyoti Bhayana, Chao-Wen Young, Tejpal Singh, Samir Shah

Patent number: 12274885Abstract: Methods and devices for managing establishment of a communications link between an external instrument (EI) and an implantable medical device (IMD) are provided. A method performed by the EI includes scanning one or more channels for an advertisement notice transmitted by the IMD in accordance with a scanning schedule, wherein the scanning schedule defines a temporal pattern of scanning windows that are separated by one or more scanning intervals. The method also includes changing the scanning schedule, in response to a duration of the scanning the one or more channels exceeding a predetermined threshold without a valid advertisement notice being received by the EI from the IMD, and scanning the one or more channels for the advertisement notice in accordance with the scanning schedule as changed, wherein the scanning schedule as changed defines a different temporal pattern of scanning windows that are separated by one or more scanning intervals.Type: GrantFiled: December 21, 2023Date of Patent: April 15, 2025Assignee: Pacesetter, Inc.Inventors: Yongjian Wu, Samir Shah, Heidi Hellman, Reza Shahandeh, Tejpal Singh, Youjing Huang, Chao-Wen Young
