SYSTEM INCLUDING GUIDEWIRE FOR DETECTING FLUID PRESSURE

摘要

A system for detection of blood pressure in a blood vessel includes a guide wire and a LC resonance circuit provided at a distal end of the guide wire. The resonance circuit may be a non-LC resonance circuit responsive to changes in pressure of fluid external to the guide wire such that the resonance circuit has a resonance frequency that varies in accordance with changes in pressure of the external fluid.
