Patent No. EP4209198 (titled "Compact Prosthetic Heart Valve Device") was filed by Medtronic on Apr 16, 2021. The application was issued on Dec 10, 2025.
A heart valve prosthesis comprises a frame featuring a valve support and an anchor element. The valve support includes a narrow upstream segment and a wider downstream segment. The anchor element is a hollow, stent-like structure partially surrounding the valve support, comprising a tissue fixation ring and multiple connectors. A prosthetic valve component is secured within the valve support, featuring leaflets that coapt within the narrow upstream segment. The leaflets' commissures are secured within the wider downstream segment, enabling the leaflets to open into the wider downstream segment during diastole. Designed for percutaneous delivery, the prosthesis is configured for implantation in native heart valves with smaller, elliptical perimeter annuli, providing mechanical isolation between the upstream segment and the anchor element.

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.
The dossier documents provide a comprehensive record of the patent's prosecution history - including filings, correspondence, and decisions made by patent offices - and are crucial for understanding the patent's legal journey and any challenges it may have faced during examination.
