Argentine Inventor of Life-Saving Heart Stent, Julio Palmaz, Dies – A Legacy of Innovation
SAN ANTONIO, TX – The medical world is mourning the loss of Dr. Julio Palmaz, the Argentine physician and inventor whose groundbreaking work revolutionized the treatment of coronary artery disease. Palmaz, best known for developing the balloon-expandable stent, passed away leaving behind a legacy that has saved millions of lives worldwide. This breaking news story details his journey from a spark of inspiration to a globally impactful medical device, and explores the future of cardiovascular care. This is a story that will undoubtedly resonate with those interested in medical innovation and the power of SEO to share vital information quickly via Google News.

From Inspiration to Invention: The Birth of the Stent
The story began in 1978, after Dr. Palmaz attended a conference led by German cardiologist Andreas Grüntzig, a pioneer in balloon angioplasty. Grüntzig’s technique – using an inflatable balloon to open blocked arteries – was a game-changer, but suffered from a high rate of re-closure. “It was like a bolt of lightning,” Palmaz recalled to the BBC. “I started thinking about it right then and there, and I was already drawing pictures on the way home on a napkin on a plane.” He envisioned a scaffold that could be placed *inside* the artery to keep it open permanently.
Palmaz’s initial experiments were remarkably resourceful. Working from his garage, he attempted to weave copper wire, but quickly realized a different approach was needed. Serendipity struck when construction workers left behind a strip of expanded metal with a unique, staggered opening pattern. “When I saw it I thought maybe that was the answer,” he explained. This accidental discovery led to the design of the Palmaz Stent – a foldable, expandable tube that could be deployed within an artery to provide lasting support.
Overcoming Obstacles: Collaboration and Funding
Bringing the stent to life wasn’t easy. Palmaz moved to the University of Texas Health Science Center in San Antonio, where he found a machine capable of creating the intricate structure he needed. Crucially, he partnered with Dr. Richard Schatz, a U.S. Army cardiologist, and secured funding from an unlikely source: Philip Romano, the owner of a fast-food chain. Later, a major pharmaceutical company recognized the potential and invested heavily in the stent’s development.

A Medical Revolution: Impact and Statistics
The Palmaz Stent received FDA approval in 1990 for use in peripheral arteries, marking the first implantable stent approved for vascular use in the United States. Its impact has been profound. Today, an estimated 2 million stents are implanted globally each year, dramatically improving the lives of patients with coronary artery disease. This procedure has largely replaced more invasive surgeries like cardiac bypass in many cases.
Coronary heart disease, a leading cause of death worldwide, occurs when fatty materials block the coronary arteries, restricting blood flow to the heart. Symptoms can range from chest pain to a full-blown heart attack. The stent provides a vital solution, restoring blood flow and preventing life-threatening events.
From Argentina to Innovation: Palmaz’s Journey
Born in La Plata, Argentina, in 1945, Palmaz pursued medical research after recognizing the opportunities available in the United States. “Research was not possible in Argentina, so I knew that if I wanted to contribute… I had to go to the United States,” he stated. His dedication and innovative spirit ultimately transformed cardiovascular medicine.
Palmaz, later in life, found peace and fulfillment in a new passion: winemaking, owning a vineyard in California. He remained a mentor to young innovators, encouraging them to pursue their ideas and “leave their mark” on the world.
While initially apprehensive about potential long-term complications, Palmaz ultimately expressed immense pride in his invention. “It still surprises me that all these years later and it’s still in use,” he said. His legacy will continue to inspire generations of medical professionals and researchers.
