with a discarded piece of metal from the floor of his garage,
Julio Palmaz invented the first commercially-successful intravascular
stent, the Palmaz Stent®. His stent revolutionized cardiac
care, with more than two a million people undergoing coronary
artery stenting annually to repair clogged arteries.
stent - an open mesh tube that once inserted expands the vessel,
holding it open to restore normal blood flow - has had a major
impact on the management of atherosclerotic arterial disease.
Specifically, it has revolutionized the management of coronary
artery disease. Many coronary bypass surgeries that would have
once been inevitable can now be avoided through stenting.
Born in Argentina, Palmaz studied at the National University of
La Plata in Argentina, earning his medical degree in 1971. He
practiced vascular radiology at the San Martin University Hospital
in La Plata, before moving to the University of Texas Health and
Science Center at San Antonio. Palmaz developed his stent, the
first balloon-expandable stent, between 1978 and 1985 at UTHSCSA,
and received a patent for his invention in 1988. It was approved
by the FDA for peripheral arterial use in 1991, and for coronary
use in 1994. Palmaz continues to innovate on his initial designs,
developing new endovascular devices.
