Wallstent® Venous Endoprosthesis with Unistep™ Plus Delivery System
The Wallstent Venous Endoprosthesis is indicated for improving central venous luminal diameter following unsuccessful angioplasty in patients on chronic hemodialysis with stenosis of the venous outflow tract. Unsuccessful angioplasty is defined as residual stenosis ≥ 30& for a vein ≤ 10mm in diameter or ≥ 50& for a vein > 10 mm in diameter, a tear which interrupts the integrity of the intima or lumen, abrupt lesion site occlusion, or refractory spasm. The vessels that can be treated with the Wallstent Venous Endoprosthesis are the innominate and subclavian veins, ranging from 8.0 mm to 15 mm in diameter.
