Irvine-based heart valve maker Edwards Lifesciences Corp. shot up on Monday after it said that a U.S. District Court judge granted a preliminary injunction on rival Medtronic Inc.’s CoreValve in the U.S.
Edwards said in a statement Friday that the ruling goes into effect in seven business days.
Edwards filed a lawsuit against Medtronic in 2008 and a jury ruled in 2010 that CoreValve infringed on Edwards’ Andersen transcatheter aortic valve replacement patent.
Edwards shares were up about 12.5% in afternoon trading Monday to a market value of $8.81 billion.
Medtronic shares were down about 2% to a market value of $58.07 billion.
