Peripheral intervention surgeries are part of the minimal invasive surgeries done to remove plaques, etc, thereby addressing the root cause of peripheral artery disease. Peripheral intervention surgeries restore the flow of blood to the other part of the arteries where the blood clot prevented the flow of oxygenated blood. These procedures require the use of a catheter, (which is a thin microfiber made of metal composites and polymers), these catheters are inserted through a thin cut in an artery, usually in an arm, leg or shoulder. These are then directed to the site of blockage/lesion/damage with the assistance of an x-ray angiogram, etc. The catheter is then used to remove the blockage by either creating a tunnel via a balloon or introducing a stent made of Nitinol or other high grade metal composites. If a balloon is used then it us removed after deflating, if a stent is used then it remains in the artery providing support to the arterial wall. Nowadays stents are used mainly for any coronary artery disease as these require support on a priority basis, any other peripheral artery may use balloon for clot removal. In atherectomy, surgeons use a catheter with small blades to cut and remove blockages, laser may be used to cauterize the wounded artery, or to burn the plaque into tiny pieces.
