The court's ruling reaffirms an earlier decision that CoreValve infringes on Edward Lifesciences' (EW) U.S. Anderson patent.
The judge orders both companies to confer on the specific instances where CoreValve can continue to be used on U.S. patients at medical centers trained on Medtronic's device.
The litigation began in 2008. In late 2013, the U.S. Supreme Court declined to hear MDT's appeal.
In a separate case, a federal jury in January found CoreValve infringes in EW's U.S. Cribier patent.
EW is up 13% premarket while MDT is down ~5%, both on light volume.
