Abstract

This study advances the technology for 'smart' antenna stents integrated with micro pressure sensors, targeting at providing a non-invasive and rapid diagnosis of stenting-induced complications in a wireless manner. The smart stent device is developed via considering both engineering and clinical practicality with enhanced electromechanical performance over reported counterparts. The fabricated prototypes are assembled on balloon catheters while withstanding crimping forces well greater than 100 N, and show wireless local pressure sensing with a resolution of 12.4 mmHg upon balloon expansion. Using a swine model, the device is successfully operated to demonstrate wireless detection of blood clot formation, as well as real-time tracking of blood pressure change over a mean arterial pressure of 108 mmHg.
