St Jude files suit against Volcano over guidewire tech
This article was originally published in Clinica
St Jude Medical has claimed that several of Volcano’s products, including the PrimeWire pressure guidewire, infringe five of its patents. St Jude has filed suit against its rival in the US District Court in Delaware in a bid to gain injunctive relief and monetary damages. St Jude’s patents cover its PressureWire technology, which it acquired from Radi Medical Systems in 2008 (www.clinica.co.uk, 22 December 2008). PressureWire measures fractional flow reserve, an index used by interventional cardiologists to evaluate the severity of blood flow blockages in the heart and better determine the most effective treatment for patients.
