Angioplasty<unk> s are small, soft, flexible, lubricated, wires that act as a rail over which equipment such as an angioplasty balloon, a stent, or an intravascular ultrasound device can be delivered over into the coronary artery.  Angioplasty<unk> s were introduced in 1982 by doctors Simpson and Roberts. The introduction of coronary<unk> s was a major advance as it allowed the angioplasty balloon to be a traumatically steered to the proper location.
