"Angioplasty" is a medical procedure implemented on humans that unblocks and/or repairs a blood vessel and in particular one's coronary artery.

In any warm blooded animal (humans for example) blood vessels move blood throughout the body as part of its circulation system. Blood vessels are broken down into three categories. First, the "arteries" that move the blood away from the heart. Second, the "capillaries" that allow the transfer of chemical components and water in the organism to be exchanged between tissue and blood. Third, the "veins" that move blood from the "capillaries" with nutrients to the heart as part of the organism's circulation system.

"Angioplasty" as a surgical technique.

For the past thirty (30) plus years, surgeons throughout the world have utilized a medical technique commonly known as "Angioplasty". This surgical procedure opens up arteries that have narrowed or have become obstructed due to many causes the commonly the aging process and the build up of fat deposits. Such obstructions restrict and impair the passage of oxygenated blood carrying nutrients throughout the body of an person which result diminished his or her overall health and ability to lead an active life. As a general rule the surgery is minimally evasive and is typically performed on an outpatient basis.

The procedure is accomplished by way of an empty balloon attached to a thin wire by the surgeon. This device is known as a "balloon catheter". The "balloon catheter" is inserted into a person's artery by the surgeon and is then inflated to a set dimension. Its expansion expands the deposits within the artery and the artery's wall increasing blood flow. If the artery collapses back to its dimension before the procedure, then a "stent" is inserted into the artery and left there to keep the expanded artery opened to its desired size. The "stent" is a thin narrow support shaped like a tube that is hollow and open at each end so as to allow blood to freely pass through the now cleaned out artery.
