Magazine ranks Palmaz® stent among '10 Patents That Changed World'

The revolutionary Palmaz® stent, which was invented at The University of Texas Health Science Center at San Antonio, is listed as one of the "10 Patents That Changed the World" in the August issue of IP Worldwide magazine. Stents are used in 2 million patients annually to repair clogged arteries near the heart and elsewhere in the body.

Julio C. Palmaz, M.D., professor of radiology at the Health Science Center, gained a U.S. patent on the stent in April 1988. The U.S. Food and Drug Administration granted approval for use in cardiac arteries in 1994.

IP Worldwide's article honors the stent's application in cardiac care. "Before stents were introduced, the gold standard was open-heart surgery, a procedure that saved countless lives but subjected patients to long hospital stays, the risk of infection, and long recovery times," the magazine's Alan Cohen wrote. "The stent procedure, which requires just a small incision, can be done on an outpatient basis, making it far less expensive than open-heart surgery — good news if your time is as precious as Dick Cheney's, who had a stent inserted in 2001."
