During the study for the aortic-aneurysm treatment, a device from Aptus Endosystems Inc. known as a stent-graft, an unusually high percentage of the study ' s participants developed blood clots in their legs or in the devices, which in several cases required emergency surgery or placement of a stent, doctors involved in the study said. ❋ Thomas M. Burton (2010)
There are now at least five FDA-approved stent-graft models on the market. ❋ Thomas M. Burton (2010)
The stent-graft device developed by Aptus of Sunnyvale, Calif., was designed to treat aortic aneurysms, which are bulges in the aorta, the main artery carrying blood through the abdomen to vital organs. ❋ Thomas M. Burton (2010)
The Aptus stent-graft, called Aptus AAA Endovascular Repair System, appears to have some potential advantages over rival devices, including a smaller profile that allows it to more easily slide into place, according to doctors who have treated aortic- aneurysm patients. ❋ Thomas M. Burton (2010)
Over time, the study showed there are drawbacks with the stent-graft, despite its short-term advantages. ❋ Unknown (2008)
This study, published in this week's New England Journal of Medicine, provides complex answers that seem to favor the stent-graft in many doctors 'minds. ❋ Unknown (2008)
New research analyzing more than 22,000 U.S. cases of aortic aneurysm repair is likely to hasten the trend toward more procedures being done with a device called a stent-graft instead of the typical surgery that requires up to eight weeks of recovery. ❋ Unknown (2008)
In a public-health notification posted on the agency's Web site, the FDA said it was focusing on Medtronic's AneuRx stent-graft system because it is the only currently marketed device that has a significant number of patients who have been followed for at least five years after receiving a device. ❋ Jennifer Corbett-Dooren (2008)
Since the mid-1990s, the fabric-and-metal stent-graft has become increasingly popular, largely because this process is easier on the patient. ❋ Unknown (2008)
Medtronic Inc. 's AneuRx stent-graft system is inserted into a patient's artery. ❋ Jennifer Corbett-Dooren (2008)
Patients tend to prefer the stent-graft process, because recovery typically takes a couple of weeks. ❋ Unknown (2008)
Potentially lethal ruptures were more common among stent-graft patients (1.8% versus 0.5%) after four years. ❋ Unknown (2008)
In addition, the incidence of freedom from subsequent interventions at 6 months was significantly greater in the stent-graft group than in the balloon-angioplasty group (32% vs. 16%, P = 0.03 by the log-rank test and P = 0.04 by the Wilcoxon rank-sum test). ❋ Unknown (2010)
