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.
For several weeks following angioplasty, patients may have a small and relatively painless bruise or lump where the sheaths were inserted. If pain or tenderness develops, the physician should be notified immediately. This may be a sign of infection or bleeding where vessels have not sealed properly.
