Patent No. EP3934581 (titled "Trans-Septal Delivery System And Methods Of Use") was filed by Medtronic on Mar 4, 2020. The application was issued on Sep 10, 2025.
This percutaneous delivery system for a heart valve prosthesis comprises a prosthesis and a multi-shaft delivery catheter. The prosthesis includes an inner valve support coupled to and at least partially surrounded by an anchoring member, capable of transitioning between radially collapsed and expanded configurations. The delivery catheter features a nested three-shaft architecture: an outer shaft, an intermediate shaft disposed within the outer shaft's lumen, and an inner shaft disposed within the intermediate shaft's lumen. In the delivery configuration, the outer shaft retains the anchoring member in a radially compressed state, while the intermediate shaft retains at least a portion of the inner valve support in a radially compressed state, enabling low-profile transport to the native valve treatment site.

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.
