A jury will begin hearing evidence today in a nasty patent spat over fractional flow reserve technology between St. Jude Medical and Volcano Corp.

St. Jude Medical, 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. The lawsuit alleges that San Diego-based Volcano's PrimeWire system violates the patents. St. Jude wants a jury to decide whether it's due a judgment of infringement, a permanent injunction barring further infringement, damages, pre- and post-judgment interest, royalties on any infringing sales and legal fees.
