Medtronic Corevalve Llc v Edwards Lifesciences AG & Anor

Medtronic Corevalve Llc v Edwards Lifesciences AG & Anor

The patent claim's reference to 'cylindrical surface' and 'cylindrical support means' must be given its ordinary meaning; the patent does not disclose or teach shaping the stent to mirror the implantation site. CoreValve's device does not infringe because its commissural points are not mounted on a cylindrical surface and the support means is not cylindrical as required by the claim.
