System and method for selectively communicating with an implantable medical device

摘要

A system may include a target implantable medical device (IMD) and an external device configured to selectively communicate with the target IMD. The external device may include a communication module configured to communicate with the target IMD, a response analysis module configured to receive and analyze a target response signal from the target IMD and other response signals from other IMDS, and a power adjustment module configured to receive one or more power-adjustment request signals from the response analysis module. The power adjustment module is configured to adaptively adjust a power of a transmission request over a first frequency band based on the one or more power-adjustment request signals until the response analysis module receives only the target response signal from the target IMD.

1. An external device comprising:
a communication module configured to communicate with a target implantable medical device (IMD) within a vicinity of other IMDs; a response analysis module configured to receive and analyze a target response signal from the target IMD and other response signals from the other IMDs and based thereon, generate one or more power-adjustment request signals; and a power adjustment module configured to receive the one or more power-adjustment request signals from the response analysis module, wherein the power adjustment module is configured to adaptively adjust a power of a transmission request over a first frequency band based on the one or more power-adjustment request signals until the response analysis module receives only the target response signal from the target IMD, wherein the external device is configured to communicate with the target IMD over a second frequency band after the response analysis module receives only the target response signal, and wherein the power adjustment module is configured to, at least one of:
incrementally decrease the power of transmission request over the first frequency band when the response analysis module receives one or more of the other signals from one of more the other IMDs, andincrementally increase the power of the transmission request over the first frequency band when the response analysis module does not receive the target response signal.
