  • Patent number: 10531878
    Abstract: An atrial appendage closure device is provided that includes an insertion rod having a first end and a second end. An occluding member having an outer surface and an inner surface is connected to the first end of the insertion rod. The occluding member is moveable between a retracted position and a deployed position such that, in the deployed position, the occluding member is configured to provide a seal between a left atrial appendage and a left atrium of a heart. An anchoring member is further connected to the insertion rod and is configured to slide along the insertion rod to secure the device to a wall of a left atrial appendage. Methods for occluding a left atrial appendage that make use of the closure devices are also provided.

  • Patent number: 10524810
    Abstract: A medical device for capturing one or more stone fragments includes a sheath having a proximal end and a distal end, a handle at the proximal end of the sheath, and a basket operable with the handle. The basket includes a plurality of wires that capture the stone fragments and has a collapsed configuration when the basket is positioned within the sheath and an expanded configuration when the basket is positioned beyond the distal end of the sheath. The medical device further includes an indicator that communicates to an operator of the medical device that the size of the stone fragments exceeds a predetermined limit and a release mechanism that releases the stone fragments from the plurality of wires when the size of the stone fragments exceeds the predetermined limit. The plurality of wires are able to reset into an operable position after releasing the stone fragments.

  • Patent number: 10507067
    Abstract: A method and apparatus for steering of a flexible needle into tissue using a steering robotic platform for manipulation of the needle shaft, and by use of a semi-active arm for locating and orienting of the steering robot on the patient's body. As opposed to other steering methods, the robot does not hold the base of the needle, which is its proximal region, but rather grips the shaft of the needle by means of a manipulatable needle gripping device, near its distal end. The needle gripper attached to the robotic platform may be equipped with a traction assembly to provide motion to the needle in its longitudinal direction, such that it co-ordinates the entry of the needle with the desired entry angle. The gripping of the needle at its distal end, close to its insertion point, provides the needle manipulator with a low profile, with concomitant advantages.

  • Patent number: 10470905
    Abstract: Apparatus and methods are provided for flaring a stent deployed within a branch vessel including an ostium communicating with a main vessel, a first end of the stent extending at least partially from the branch. A catheter is provided that includes a balloon having a reinforced region adjacent an unreinforced region. When the balloon is positioned at a desired location, e.g., within a stent, prosthetic valve, or other tubular prosthesis, the balloon may be inflated to a first pressure causing the reinforced and unreinforced regions to expand substantially simultaneously. Upon inflation of the balloon beyond the first pressure, the reinforced region of the balloon remains at the first diameter and the unreinforced region continues to expand, e.g., to flare one or more ends of the prosthesis.

  • Patent number: 10463393
    Abstract: A circumcision device comprises a hollow bell-shaped body, a semi-conical part, and a handle. The body comprises an open anterior end, an open posterior end, a circumferential flange proximal to the open anterior end on an exterior surface of the body. The semi-conical part comprises an open anterior end and an open posterior end. The open posterior end extends from the circumferential flange. The open anterior end of the semi-conical part prevents slippage of the circumcision device to a shaft of a penis on which the circumcision device is configured to be mounted, when the circumcision device is mounted on the penis. The handle has an inverted Y-shape comprising two forked legs, each of the two forked legs coupled to a periphery of the open anterior end of the semi-conical part, the coupling forming a junction. The junction is formed structurally weak to facilitate detaching the handle from the semi-conical part.

  • Patent number: 10463479
    Abstract: Anchoring or docking devices configured to be positioned at a native valve of a human heart and to provide structural support for docking a prosthetic valve therein. The docking devices can have coiled structures that define an inner space in which the prosthetic valve can be held. The docking devices can have enlarged end regions with circular or non-circular shapes, for example, to facilitate implantation of the docking device or to better hold the docking device in position once deployed. The docking devices can be laser-cut tubes with locking wires to assist in better maintaining a shape of the docking device. The docking devices can include various features to promote friction, such as frictional cover layers. Such docking devices can have ends configured to more securely attach the cover layers to cores of the docking devices.

  • Patent number: 10456161
    Abstract: A tissue removing catheter includes an apposition mechanism that selectively imparts an axially compressive load on the catheter body to bend the catheter and urge a tissue-removing element toward a blood vessel wall. The apposition mechanism can include one or more adjustment lines and an adjustment mechanism for selectively tensioning one of the adjustment lines to impart the compressive load on the catheter body. Two adjustment lines can have diametrically opposed positions and be wound onto a spool of the adjustment mechanism in opposite directions so that rotation of the spool simultaneously shortens one adjustment line and lengthens the other. The catheter body can have a more flexible bending segment adjacent the tissue-removing element to promote bending near the tissue-removing element operative to urge the tissue-removing element in apposition with the blood vessel.

  • Patent number: 10449045
    Abstract: A system and method for restoring (e.g., replacing) a defective heart valve of a patient. A delivery system is manipulated to percutaneously deliver and implant a stented prosthetic heart valve to a native heart valve. A post-dilatation balloon is percutaneously delivered to the implantation site, and a compliant segment thereof is arranged within a region of the implanted prosthesis. The balloon is inflated such that the compliant segment expands and contacts the prosthesis, expanding a remodeling region of the prosthesis to a remodeled state. With these and related techniques, remodeling of an implanted, stented prosthetic heart valve to better match the native valve shape is possible, providing many benefits such as reducing the risk of paravalvular leaks.

  • Patent number: 10448939
    Abstract: Embodiments include systems and methods for closure of a hole or other defect, for example in context of a laparoscopic surgical procedure. For example, a suturing device and method of use involve inserting the device into a hole, positioning material around the hole into a notch of the device, passing a needle through a cavity in the device and the material positioned in the notch, passing a suture through the eye of the needle, and removing the needle from the material with the suture. The suture can be removed and the process can be repeated with another end of the suture at another location through the material, around the hole. When the suture is passed through the second point of penetration, the suture can now extend both into and out of the material at different points around the hole and can be tied, thereby closing the hole.
