Many aspects of an animal or plant can be correctly called adaptations, though there are always some features whose function is in doubt. By using the term adaptation for the evolutionary process, and adaptive trait for the bodily part or function (the product), the two senses of the word may be distinguished.
Angioplasty (or Balloon angioplasty) is an endovascular procedure to widen narrowed or obstructed arteries or veins, typically to treat arterial atherosclerosis. An empty, collapsed balloon, known as a balloon catheter, is passed over a wire into the narrowed locations and then inflated to a fixed size.
Angioplasty is a catheter-based procedure to reopen blocked arteries and stop a heart attack in progress. For the procedure, a catheter â a thin plastic tube â is inserted through a puncture site in the skin near the groin or in the wrist, and a tiny wire is guided to the site of the blockage.
