Medtronic has received clearance from the FDA to market a new stent for supporting the heart's more tortuous arteries. The Wiktor Rival system is for treating abrupt or threatened vessel closure in patients with failed interventional therapy or suboptimal percutaneous transluminal coronary angioplasty. The device, which was granted a PMA supplement, has low deployment and post-deployment pressures to protect vessel tissue and eliminate the need for high-pressure balloon catheters, which are time consuming to use and add to cost.
