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.
A American Diabetes Association answered. Angioplasty, also called percutaneous coronary intervention (PCI) or balloon angioplasty, is a procedure used to remove a blockage in a blood vessel to the heart (coronary angioplasty) or the brain (carotid angioplasty). A small tube with a balloon attached is threaded into the narrowed or blocked blood vessel. Then the balloon is inflated, opening the narrowed artery. A wire mesh tube, called a stent, may be left in place to help keep the artery open. Angioplasty may be done during a heart attack.
