  • Patent number: 10285677
    Abstract: A vascular closure system includes a suture and an anchor assembly. The anchor assembly includes a first anchor portion having a plurality of petal members automatically expandable from a retracted position for delivery through a vessel puncture in a vessel, and an expanded position when deployed within the vessel. The anchor assembly also includes a second anchor portion connected to the suture and positioned distal of the first anchor portion within the vessel. Withdrawing the suture pulls the second anchor portion against the first anchor portion to contact the first anchor portion against an inner surface of the vessel adjacent to the vessel puncture. The vascular closure system may also include an automatic compaction assembly that automatically compacts a sealing member against the anchor assembly to seal closed the vessel puncture upon withdrawal of the vascular closure system.

  • Publication number: 20170319333
    Abstract: In some embodiments, a method includes delivering to a native valve annulus (e.g., a native mitral valve annulus) of a heart a prosthetic heart valve having a body expandable from a collapsed, delivery configuration to an expanded, deployed configuration. The method can further include, after the delivering, causing the prosthetic heart valve to move from the delivery configuration to the deployed configuration. With the prosthetic heart valve in its deployed configuration, an anchor can be delivered and secured to at least one of a fibrous trigone of the heart or an anterior native leaflet of the native valve. With the prosthetic heart valve disposed in the native valve annulus and in its deployed configuration, an anchoring tether can extending from the anchor can be secured to a wall of the heart to urge the anterior native leaflet towards the body of the prosthetic heart valve.
