An Implantable Biocompatible Smart Stent for Monitoring Eventual Restenosis

Abstract

An implantable device such as a stent is discussed in this article. The device has a tubular structure with a longitudinal cavity that extends from the first to the second end, with two or more ultrasonic transductors positioned properly, so that an ultrasonic signal is produced and received which spreads through a transducer in the cross cavity of the device. The transducer works in pairs by sending a signal one to another. The transducers function with one signal to the other. Using various methodologies based on requirements, the ultrasounds signal can measure blood flow rate. The system proposed can detect even a partial block of the cavity, which can also predict the initiation of restenosis phenomena.
