Brief summary
Collect confirmatory evidence of the safety and effectiveness of the Balloon LIFESTREAM™ Stent Graft for the treatment of stenoses and occlusion in the iliac arteries.
Interventions
Percutaneous transluminal angioplasty (PTA) is a procedure that can open up a blocked blood vessel using a small, flexible plastic tube, or catheter, with a balloon at the end of it. When the tube is in place, it inflates to open the blood vessel, or artery, so that normal blood flow is restored.
