We present a novel shape memory alloy nitinol type active stent for non-invasive restenosis treatment, which operates using a radiofrequency electro-thermo-mechanical actuation technique for wireless revascularization. The stent is equipped with sensing capability for in-artery blood pressure measurement and can provide multiple expansion to restore the blood flow. The electrical and mechanical properties, thermal and temporal response of the stent are characterized. In addition, ex vivo characterization of the developed stent is also performed. The achievable wireless revascularization capability eradicates the necessity of reintervention and repeat stenting procedure, whereas real-time wireless monitoring provides rapid indication of in-artery re-narrowing occurrence. read more
