Literally meaning: “vessel forming” or “vessel molding””

The term was coined in January of 1964 by vascular radiologist Charles Dotter (1920-1985) who invented the catheter-delivered stent and performed the first angioplasty in an 82-year-old woman with painful leg ischemia. Dotter claimed that “catheters should replace scalpels” but it was not until around 1980 that this technique gained acceptance in US.

Angioplasty is a non-surgical procedure which is performed for arteries widening with a help of catheter. Usually angioplasty referred to confined or scattered areas of blockage within a coronary artery due to atherosclerosis.
