The SFA is the longest artery in the arterial circulation with the fewest side branches, and it is fixed between two major flexion joints, the hip and the knee. Multiple geometric forces are exerted on the SFA during routine movements. These forces include longitudinal and lateral compression, flexion, elongation, and torsion.

2023年3月24日 · The femoral artery (FA) (TA: arteria femoralis) 6 is the continuation of the external iliac artery (EIA) below the level of the inguinal ligament. As well as supplying oxygenated blood to the lower limb, it gives off smaller branches to …

The Innova Stent System is designed to provide a precise, predictable experience for vascular interventionalists. It is purpose-built for the treatment of SFA lesions and expertly engineered for smooth deployment and accurate placement.

During the past decade, multiple technologies have been developed for treatment of superficial femoral artery (SFA) atherosclerotic disease, including balloon angioplasty, bare nitinol self-expanding stents, drug-eluting nitinol stents, and drug-coated balloons.

Self-expanding stents should generally be at least one size larger than the vessel diameter to ensure adequate contact with the vessel wall; however, the greater the size ratio, the more COF is exerted onto the vessel wall, which can result in mechanical stress that may increase neointimal hyperplasia and restenosis. 1* To evaluate the role of ...

2018年10月17日 · Sheath sizes used for the SFA intervention range from 4 to 7 French. Sheaths protect the access vessel during the catheter intervention and wire exchanges during a procedure. The smallest size sheath to complete the intervention should be used. A reverse curved catheter and a 0.035-in guide wire are usually used to crossover the aortic bifurcation.

INTENDED USE / INDICATIONS FOR USE: The InnovaTM Vascular Self-Expanding Stent System is indicated to improve luminal diameter in the treatment of symptomatic de-novo or restenotic lesions in the native superficial femoral artery (SFA) and/or proximal popliteal artery (PPA) with reference vessel diameters from 4.0 mm to 7.0 mm and lesion ...

Current literature favors the use angioplasty for short (~4 cm) SFA stenoses or occlusions due to comparable patency and results. Primary stenting using Nitinol stents may be a superior initial treatment for intermediate (6-8 cm) and long (>10 cm) length lesions.

Revascularization procedures in the superficial femoral artery (SFA) account for more than half of all endovascular procedures that are performed. The SFA also remains the most difficult peripheral artery in which to maintain reliable long-term patency despite the rapidly increasing availability of endovascular therapy tools.

2006年2月18日 · Treatment of the superficial femoral artery (SFA) has been among the least effective of all endovascular procedures in terms of long-term patency. The relatively small vessel lumen, in conjunction with a high plaque burden, slow flow, and a high frequency of primary occlusions, contributes to a considerable rate of acute technical failures.
