NEW YORK (AP) -- Medical device maker Medtronic Inc. said Wednesday it won a lawsuit over a patent on stent grafts that are used to treat aneurysms in the aorta, the largest artery in the body.
The Minneapolis company said a judge in the Eastern District Court of Virginia ruled in its favor last week, saying Medtronic's method of making stent grafts did not violate a patent that belongs to W.L. Gore & Associates, a privately held company based in Newark, Del.
Stents are mesh-metal tubes that are placed into arteries to prop them open after they have been surgically cleared of fatty plaque.
Shares of Medtronic picked up 67 cents to $37.98 in afternoon trading.
