A jury will begin hearing evidence today in a nasty patent spat over fractional flow reserve technology between St. Jude Medical and Volcano Corp. A jury trial is set to begin today in a patent infringement lawsuit filed by St. Jude Medical (NYSE:STJ) against Volcano (NSDQ:VOLC) over fractional flow reserve technology. St. Jude sued Volcano in July 2010 in the U.S. District Court for Delaware, accusing it of violating a quintet of patents St. Jude acquired in its 2008 buyout of Radi Medical Systems AB, a Swedish guidewire maker. The patents cover STJ's PressureWire system, which uses a sensor to measure arterial blood pressure by calculating fractional flow reserve associated with stenosis in patients with coronary artery disease, according to court documents.
