FDA Approves Medtronic Protégé™ GPS™ Stent for Iliac Artery Stenosis

Medtronic plc has announced that its Protégé™ GPS™ self-expanding peripheral stent system has gained U.S. FDA approval for the treatment of stenotic lesions of the common and external iliac arteries.

Background

Iliac stenosis occurs when plaque builds up in the iliac artery, which can block the blood supply to the entire leg. As a result, patients with iliac artery stenosis can experience pain that can limit mobility.

The Protégé GPS self-expanding peripheral stent system allows physicians to treat iliac artery lesions and restore blood flow with large diameter stents through a low, 6F profile delivery system. The stent is cut from a nitinol tube into an open lattice design and has tantalum radiopaque markers at its proximal and distal ends. Upon deployment, the stent achieves its predetermined diameter and exerts a constant, outward force to restore patency.

The FDA approval follows nine-month results from Medtronic’s DURABILITY Iliac study, which were presented at the 2014 VIVA conference in Las Vegas. The results demonstrated the safety and effectiveness of the Protégé GPS peripheral stent system in the treatment of stenotic lesions of the common and external iliac arteries. The prospective, multi-center, non-randomized clinical study demonstrated 95.8 percent nine-month primary patency by Kaplan-Meier analysis and 98.6 percent freedom from target vessel revascularization.

Investigator comments

“When used for iliac angioplasty and stenting, the Protégé GPS self-expanding peripheral stent system demonstrated excellent patency rates even in difficult-to-treat calcified lesions,” said Dr. Peter Faries, co-national principal investigator of the DURABILITY Iliac study, Mount Sinai School of Medicine, New York. “Data from the DURABILITY Iliac study confirms the safety and effectiveness of the Protégé GPS stent. It is gratifying to see that the FDA has approved this stent for the iliac indication.”

Company comments

“The Protégé GPS self-expanding peripheral stent system is designed to enhance delivery, deployment and visibility during peripheral vascular procedures,” said Mark Turco, M.D., medical director of the Aortic and Peripheral Vascular business at Medtronic. “This new indication will provide physicians with enhanced device options when treating complex iliac artery disease.”
