    摘要: A device for sealing a left atrial appendage includes an anchor element, a sealing element, and a coupling element. The anchor element is configured to anchor the device to tissue in or adjacent the left atrial appendage. The sealing element is configured to seal the left atrial appendage and prevent thrombus from embolizing therefrom. The coupling element joins the anchor element with the sealing element. A delivery catheter may be used to deliver the sealing device.

    摘要: A catheter includes a shaft having a distal end, an expandable member secured to the distal end, and an anchoring device positioned distal to the expandable member. The anchoring device having a delivery configuration and a deployed configuration. By way of one example, the anchoring device may comprise a shaped (e.g., helical) wire, the anchoring device having a cross-sectional dimension that allows it to secure itself inside a pulmonary vein when in its deployed configuration.

    摘要: A transseptal needle and other structures and methods may include an outer conduit, for example one that may be subject to skiving, and a needle or other sharp structure within the outer conduit. A material no softer than the needle is positioned between the needle and the outer conduit so that the needle does not skive the inside surface of the outer conduit when the needle and outer conduit move relative to each other.
