The recent controversy over the use of paclitaxel in the peripheral vasculature has clouded the larger debate over whether bypass is superior to endovascular therapies for the lower limbs. However, a new study suggests that nitinol stents provide a feasible alternative to bypass even for lesions of the femoropopliteal artery that are 30 cm in length.
The U.S. FDA has given Pq Bypass Inc. the greenlight to conduct a pivotal trial aimed at assessing its Torus stent graft in the treatment of peripheral artery disease (PAD) in the superficial femoral artery. The TORUS-2 study is the Milpitas, Calif.-based startup's second IDE approval in less than two years and the first pivotal IDE for an SFA stent graft since W.L. Gore & Associates Inc.'s Viabahn device, which notched an initial PMA approval in 2005.
