Co-inventor of the Palmaz-Schatz Stent. Julio Palmaz (December 13, 1945 in La Plata , Argentina ) is a doctor of vascular radiology at University of Texas Health Science Center at San Antonio . He studied at the National University of La Plata in Argentina, earning his medical degree in 1971.
Stent technology improved rapidly, and in 1989 the Palmaz-Schatz balloon-expandable intracoronary stent was developed. [24] [25] Initial results with the Palmaz-Schatz stents were excellent when compared to balloon angioplasty, with a significantly lower incidence of abrupt closure and peri-procedure heart attack. [26]
Shortly thereafter, in 1987, Julio Palmaz (known for patenting a balloon-expandable stent [20]) and Richard Schatz implanted their similar stent into a patient in Germany. Though several doctors have been credited with the creation of the stent, the first FDA-approved stent in the U.S. was created by Richard Schatz and coworkers.
Coronary artery stents, typically a metal framework, can be placed inside the artery to help keep it open. However, as the stent is a foreign object (not native to the body), it incites an immune response. This may cause scar tissue (cell proliferation) to rapidly grow over the stent and cause a neointimal hyperplasia.
The first device was simple, according to Parodi: “It was a graft I designed with expandable ends, the extra-large Palmaz stent, a Teflon sheath with a valve, a wire, and the valvuplasty balloon, which I took from the cardiologists." Juan Parodi invited Julio Palmaz to participate in the case at the Instituto Cardiovascular de Buenos Aires.
He also had surgery for a partially collapsed lung in 2005 and had two stents implemented in one of his coronary arteries in 2010. During his two terms at the White House, Clinton was fitted with ...
Heart disease is the No. 1 cause of death in the U.S. Yet, according to the American Heart Association, half of Americans are unaware of this sobering statistic. The good news is that a diet ...
Percutaneous coronary intervention (PCI) is a minimally invasive non-surgical procedure used to treat narrowing of the coronary arteries of the heart found in coronary artery disease. [2] The procedure is used to place and deploy coronary stents , a permanent wire-meshed tube, to open narrowed coronary arteries.
