Terumo Launches Self-Expanding Stent in U.S.

Japanese devicemaker Terumo launched its Misago Rx self-expanding peripheral stent in the U.S. market last week, following receipt of premarket approval in May.

The Misago system, comprised of a nitinol stent premounted onto the distal portion of a rapid-exchange delivery catheter, is intended to treat peripheral artery disease in the superficial femoral and proximal popliteal arteries. The product has been available in territories outside the U.S since 2008.

A multicenter clinical trial — one of the first harmonization-by-doing initiatives between the U.S. and Japan — demonstrated a low potential for stent fracture, precision deployment by a single operator at the lesion site, sustained patency of almost 83 percent at one year and 88.6 percent freedom from target lesion revascularization at one year, Terumo said.
