Systems And Methods For Incorporating A Patch Antenna In An Implantable Medical Device

View page
US Patent:
20210167488, Jun 3, 2021
Filed:
Feb 12, 2021
Appl. No.:
17/175187
Inventors:
- Sylmar CA, US
Lequan Zhang - La Crescenta CA, US
Assignee:
Pacesetter, Inc. - Sylmar CA
International Classification:
H01Q 1/27
H01Q 9/04
H01Q 1/22
A61N 1/372
Abstract:
Systems and methods for an implantable medical device which utilizes a patch antenna for communicating with an external device. The implantable medical device includes a housing, a header, and a patch antenna formed using an RF plate and a ground plate, which may be or include a metal surface of the housing. Also, a material of the header forms a dielectric of the patch antenna.

US Patent:
20200383053, Dec 3, 2020
Filed:
Aug 17, 2020
Appl. No.:
16/994951
Inventors:
- Syllmar CA, US
Lequan Zhang - La Crescenta CA, US
Xing Pei - Thousand Oaks CA, US
Jeffery Crook - Belmont CA, US
Yongjian Wu - Saratoga CA, US
Jun Yang - Valencia CA, US
Chao-Wen Young - Cupertino CA, US
International Classification:
H04W 52/02
H04W 4/80
G16H 40/40
A61N 1/372
H04Q 9/00
A61B 5/00
Abstract:
A method for managing power during communication with an implantable medical device, including establishing a communications link, utilizing a power corresponding to a session start power, to initiate a current session between an implantable medical device (IMD) and external device. A telemetry break condition of the communications link is monitored during the current session. The power utilized by the IMD is adjusted between low and high power levels, during the current session based on the telemetry break condition. The number of sessions is counted, including the current session and one or more prior sessions, in which the IMD utilized the higher power level, and a level for the session start power to be utilized to initiate a next session following the current session is adaptively learned based on the counting of the number of sessions.
