Patent No. EP3311779 (titled "Stents, Valved-Stents And Methods And Systems For Delivery Thereof") was filed by Boston Scientific on Oct 27, 2008. The application was issued on Apr 24, 2024.
A minimally invasive cardiac valve replacement system that enables replacement of heart valves without open-chest surgery or cardiopulmonary bypass. The system includes a valved-stent that combines a stent and a biological or synthetic valve, and a delivery system that allows controlled deployment of the valved-stent through a small incision in the chest. The valved-stent is designed to expand and stabilize in place, with features such as a double PET fabric skirt to prevent injury to surrounding tissues. The delivery system includes a sheath that constrains the valved-stent during deployment, allowing for precise control over the expansion process.

Patent oppositions filed by competitors challenge the validity of a granted patent. These oppositions are typically based on claims of prior art, lack of novelty, or non-obviousness. They are a key part of the process for determining a patent's strength and enforceability.
