  • Publication number: 20220226105
    Abstract: A method of delivering a valve prosthesis to be deployed within a native heart valve at a native heart valve annulus. The method including collapsing a prosthetic valve having an expandable frame comprising a proximal end and a distal end and a longitudinal axis extending therethrough inside of a delivery instrument, such that a plurality of spaced anchors extending from the distal end of the expandable frame towards the proximal end are collapsed to an inverted position in a collapsed anchor configuration. The method further including advancing the delivery instrument a first distance such that the plurality of spaced anchors extend below the valve annulus, and releasing each of the plurality of spaced anchors such that each of the plurality of spaced anchors is repositioned from the inverted position to an expanded anchor configuration to contact a subannular location.

  • Publication number: 20210154010
    Abstract: Prosthetic heart valves described herein can be deployed using a transcatheter delivery system and technique to interface and anchor in cooperation with the anatomical structures of a native heart valve. Some embodiments of prosthetic mitral valves described herein include an anchor portion that couples the prosthetic mitral valve to the anatomy near the native mitral valve, and a valve portion that is mateable with the anchor portion. Some embodiments of the transcatheter delivery system can include systems and techniques for retrieval of the anchor portions and the valve portion.

  • Patent number: 10314667
    Abstract: A cleaning device for cleaning a medical instrument. First and second body portions in a closed position define a flushing chamber. The medical instrument extends through the flushing chamber. First and second sealing members secured to the first and second body portions engage one another to seal the flushing chamber and engage the medical instrument to form a seal thereabout. Portions of at least the first sealing member are disposed within the flushing chamber. Positive pressure in the flushing chamber urges the first sealing member toward the second and toward the medical instrument to enhance the tightness of the flushing chamber seal.

  • Patent number: 10292721
    Abstract: A catheter includes a tissue-removing element and a tissue-containment chamber configured to receive tissue removed by the tissue-removing element. The tissue-containment chamber has a tissue-removing opening for use in removing tissue from the chamber. A closure component is associated with the tissue-removing opening for selectively opening and closing the opening.

  • Publication number: 20190110808
    Abstract: A cleaning device for cleaning a catheter lumen of a tissue removal catheter has a flushing chamber with distal and proximal seals and an inlet port. The proximal seal is a duckbill seal that includes a pair of opposing duckbill members that slidingly accept the distal end portion of a catheter body to form a seal about the catheter body proximal to a proximal opening in of the catheter lumen. Fluid is directed in the inlet port, into the flushing chamber, into proximal opening in the catheter body, and through the catheter lumen to discharge tissue contained in the catheter lumen. In some embodiments, the cleaning device is preloaded on the catheter body. The cleaning device can have an internal stop that engages with an external stop on the catheter body when the cleaning device is positioned in an operative position.
