IMPLANTABLE WIRELESS SENSOR FOR BLOOD PRESSURE MEASUREMENT WITHIN AN ARTERY

摘要

Intra-arterial blood pressure is monitored by inserting a pressure transduce r sensor (250) using a catheter (258) into an artery and then using a small, hand-held read out device to measure pressure easily, safely, inexpensively and accurately. In one aspect a sensor (250) is introduced into the body by the steps of folding or rolling the sensor into a cylinder, loading it into a catheter, and deploying into the artery by allowing it to unroll or unfold, either by itself or facilitated by the incorporation of a super-elastic allo w component.
