Heart Valve Sealing Devices And Delivery Devices Therefor
Patent No. EP4420635 (titled "Heart Valve Sealing Devices And Delivery Devices Therefor") was filed by Edwards Lifesciences on May 13, 2016. The application was issued on Sep 24, 2025.
Patent Summary
A prosthetic device for treating heart valve regurgitation comprises a non-cylindrical spacer body and a pair of anchors. The spacer body, featuring an atrial end, a ventricular end, and an annular side surface, is configured for positioning within a native valve orifice between at least two native leaflets. Each anchor is coupled to a shaft that also attaches to the spacer body. The anchors are positioned behind the native leaflets, capturing each leaflet between the anchor and the spacer body to secure the device. When deployed, the device reduces the overall area of the native valve orifice and divides it into two separate orifices during diastole, utilizing the captured leaflets to resist embolization.
