First Claim
Patent Images
1. A blood pressure sensor apparatus for periodically measuring a blood pressure in a blood vessel, the blood pressure sensor apparatus comprising:
- an implanted sensor having a capacitor electrically connected to an implant inductor, the implanted sensor being adapted to be positioned adjacent the blood vessel such that the capacitor is operatively influenced by the blood pressure in the blood vessel;
an external reader having an external inductor adapted to be inductively coupled to the implant inductor; and
a means for determining the blood pressure at the capacitor using the implant inductor and the external inductor.

Abstract
An implanted sensor for measuring pressure in a conduit through a wall has a main body and a probe. The main body includes an implant inductor. The probe has capacitor electronically connected to the implant inductor. The probe is adapted to fit through the wall so that the capacitor can sense pressure in the conduit.
