The first and only retrievable stent system that features a self-expanding stent with an integrated dilatation balloon catheter on an over-the-wire system. It is designed for controlled lesion penetration and treatment through a series of radially expandable spikes. Known as Retrievable Scaffold Therapy (RST), the spikes on the Spur Stent penetrate the lesion to increase the acute luminal diameter and modify the lesion morphology to change vessel compliance and reduce vessel recoil effect.
