The distal end of the catheter has a conventional nylonblend balloon and a nitinol scoring element with three or more (depending on balloon size) spiral struts that wrap around the balloon. The struts create focal concentrations of dilating force, which minimize balloon slippage and assists in the luminal expansion of stenotic arteries.
The PTA Scoring Balloon Dilation Catheter is suitable for percutaneous transluminal angioplasty (PTA) of the peripheral vascular system (including the iliac, femoral, iliac-femoral, popliteal,infra popliteal,and renal arteries),and for the treatment of obstructive lesions of native or synthetic arteriovenous dialysis fistulae. Not for use in the coronary or neuro-vasculature.
