Latest Bare-metal stent Stories

MUNICH, Germany, September 1 /PRNewswire-FirstCall/ -- Biosensors International Group, Ltd ("Biosensors", "Company"), (Bloomberg: BIG:SP), (Singapore:B20) today announced that a next-generation drug-eluting stent, developed by Biosensors, has demonstrated equal safety and efficacy as compared to Johnson & Johnson's industry leading drug-eluting stent, CYPHER SELECT(TM) ("Cypher"), based upon nine-month clinical and angiographic follow-up data. The results of the landmark study were presented...

Reflecting its ongoing commitment to patient safety and clinical research, Medtronic, Inc. (NYSE: MDT), announced today the initiation of the first investigational sites in the United States to participate in PROTECT,(1) the company's global study comparing the Endeavor(R) and Cypher(R) drug-eluting stents on key safety metrics, including stent thrombosis - a rare but serious adverse event in which a blood clot forms inside the stent, with the potential to cause heart attack or death. Dr....

By Bruce Japsen, Chicago Tribune Jul. 3--While U.S. approval of Abbott Laboratories' drug-coated heart stent is a boost to the North Chicago medical giant, the product enters a market that is shrinking as doctors rethink the role of artery-clearing devices in the prevention of heart attacks and treatment of coronary artery disease. The U.S. Food and Drug Administration on Wednesday approved Abbott's Xience, which analysts believe will become the leader in a U.S. drug-coated-stent market...

U.S. medical scientists say the increasing use of drug-releasing coronary artery stents does not increase the risk of death, compared with bare-metal stents. There has been a growing concern about the possibility of an increased risk of stent thrombosis (the formation of a clot in a blood vessel) associated with the use of drug-eluting stents compared with bare-metal stents, said Dr. David Malenka of the Dartmouth-Hitchcock Medical Center in Lebanon, N.H. Although other data may suggest...

PHILADELPHIA -- When cardiologists prop open blocked arteries with the lifesaving metal cylinders known as stents, inevitably there is some damage to the cells that line the blood vessel walls _ damage that may not heal properly on its own. A team of Philadelphia researchers now thinks it can address the problem by borrowing a trusty concept from Physics 101: magnets. The scientists implanted stents in the carotid arteries of rats, then placed the animals between two large electromagnets,...

By Bosiers, M Deloose, K; Verbist, J; Peeters, P Aim. We investigated the efficacy of Xpert (Abbott Vascular Devices) nitinol stents for the treatment of infrapopliteal lesions In patients with critical limb ischemia (CLI). Methods. Between May and October 2005,47 CLI patients (35 men, mean age 73 years) received 67 Xpert stents for the treatment of 58 infrapopliteal lesions in 51 limbs; 43 patients (84.3%) were classified in Rutherford Category 4 and 8 (15.7%) in Category 5. Clinical...

WASHINGTON -- Federal health officials asked experts Thursday whether the drug-coated stents used to prop open the arteries of about 3 million people in the U.S. pose a heightened risk of death or raise other safety concerns that require action.The two manufacturers of the widely used devices say their benefits outweigh their risks, but the Food and Drug Administration believes patients could face a small but significant chance of blood clots.The companies, Boston Scientific Corp. (BSX) and...

CHICAGO (Reuters) - Heart patients whose coronary arteries reclogged after treatment with a bare-metal stent can be treated by simply inserting a newer, drug-eluting stent inside the old stent, new data suggests. Two clinical studies indicate that inserting a stent covered with the drug paclitaxel or sirolimus inside the old clogged stent reduces the risk of the vessel re-narrowing when compared with in-vessel radiation treatment. A re-narrowing of the vessel, known as in-stent...

LOS ANGELES "“ Over time, veins removed from the legs (saphenous veins) and attached to the heart to replace clogged coronary arteries tend to resemble old, sluggish drain pipes. In fact, within five to 10 years of coronary artery bypass surgery, half of all vein grafts become diseased to the point of requiring re-intervention "“ either repeat open-heart surgery or balloon angioplasty with the insertion of a stent.Stents can be inserted into a grafted vein or into a native coronary artery...

After completing the most comprehensive U.S.-based study of its kind, Dr. Charles Simonton reported that the performance of two competing coronary stents was "virtually identical" in head-to-head comparisons. Simonton, a cardiologist associated with the Carolinas Heart Institute at Carolinas Medical Center, summarized his conclusions at the annual TCT (Transcatheter Cardiovascular Therapeutics) meeting in Washington DC. TCT is recognized as the world's largest scientific symposium...
