Development of a Telemetric System for Postoperative Follow-up of Vascular Surgery Procedures: In Vitro Model.

Background: Because of the unique electromagnetic characteristics of the magnetoelastic microwire, the changes in the pressure of a fluid will provoke a variation of the mechanical pressure on the sensor, which will cause a variation of its magnetization that will be detectable wirelessly. Thus, a wireless system can be developed for following up vascular surgery procedures.

Methods And Results: The sensor consists of a magnetoelastic microwire ring, which was integrated into an in vitro model with pulsatile flow.
