Wireless Hyperthermia Stent System for Restenosis Treatment and Testing with Swine Model
Stenting is a common approach to treating atherosclerosis, the main pathology that leads to cardiovascular disease causing thousands of death each day. Despite its proven efficacy, the long-term results of stenting are still limited by re-narrowing of stented artery known... Read more

Wireless Hyperthermia Stent System for Restenosis Treatment and Testing with Swine Model
This work presents a wirelessly powered stent system developed towards endohyperthermia treatment of in-stent restenosis, renarrowing of stented artery. The gold-coated stainless-steel stent is designed to form a radiofrequency resonator with an integrated capacitor microchip. Upon deployment, the stent serves as an efficient wireless heater as part of the resonant power transfer system, applying mild heat to the local artery to inhibit restenosis, as activated using a tuned electromagnetic field supplied from the system. The prototype is tested in vitro, and then in vivo using swine models, to reveal promising results as an essential step towards clinical application of the technology... Read more
