Reflow Medical ‘Breakthrough’ for Stent System
FDA has granted Reflow Medical a breakthrough device designation for the Temporary Spur Stent System, a novel retrievable stent technology intended for treating below-the-knee (BTK) peripheral artery disease. The combination device comprises a “patented retrievable stent system having a series of radially expandable spikes designed to create multiple pathways to deliver antiproliferative drugs for increased uptake into the vessel wall and facilitate acute luminal gain, without leaving anything behind,” the company says. It was developed in response to unmet clinical needs resulting in high rates of restenosis and treatment challenges in patients with BTK disease, it says.
