Abstract

The invention includes systems and methods for converting absolute pressure data acquired in anatomical environments to gauge pressure data using an implant configured to monitor pressure. The implant is configured to communicate with an external controller, which is configured to communicate with a remote microprocessor that includes real-time barometric pressure data for one or more geographic locations.

Claims

1. A system for measuring pressure in a body, comprising:

an implant device configured for measuring absolute pressure in a body, the implant device further configured to communicate measured absolute pressure information outside of the body using telemetric signals; and

an external monitor configured to

receive telemetric signals from the implant device,

receive barometric pressure information from a remote source, the barometric pressure information associated with a geographic location of the body, and

derive gauge pressure from the received absolute pressure information and barometric pressure information
