Medtronic Could Pay $394 Million to Edwards in CoreValve Case

Medtronic willfully infringed on an Edwards Lifesciences' patent with its CoreValve transcatheter heart valve, and owes Edwards nearly $394 million in damages and patent royalties, a federal jury in Delaware found Wednesday.

The ruling is a big deal for Edwards. The company has had trouble meeting U.S. sales projections for its flagship product: the Sapien percutaneous heart valve, which is still the only transcatheter aortic valve replacement product on the domestic market.

Medtronic entering the U.S. market with the CoreValve could further erode sales for the Sapien.

Medtronic had success last year getting the CoreValve back on the German market on appeal.

At the same time, Edwards cited a federal jury finding in 2010 that Medtronic CoreValve LLC willfully infringed on Edwards' U.S. Andersen transcatheter heart valve patent, and awarded damages to Edwards. The finding was upheld on appeal, with Medtronic making an initial payment of $84 million to Edwards last year.

January has not been a good month for Medtronic. The company announced last week that its Symplicity renal denervation system for treatment-resistant hypertension failed to meet its efficacy endpoint in its U.S. pivotal trial.
