  • Patent number: 10463389
    Abstract: An atherectomy device for removing deposits such as plaque from an interior of a vessel including an outer member and a rotatable shaft positioned for rotational movement within the outer member and fixed axially within the outer member. A tip is mounted to the distal region of the rotatable shaft and is positioned distally of the distal end of the outer member to create a gap between the proximal end of the rotatable tip and the distalmost edge of the outer member. The rotatable tip has a longitudinal axis mounted to the rotatable shaft for rotation about its longitudinal axis upon rotation of the shaft, the shaft including a guidewire lumen for receiving a guidewire to enable over the wire insertion of the device.

  • Patent number: 10448946
    Abstract: A suture cinch, cinch applicator, and cinch loader for loading the cinch into the applicator are provided and permit re-use of the applicator with multiple cinches during an endoscopic procedure. The applicator can be loaded with a first cinch, apply the first cinch onto a portion of suture to fix the portion of suture relative to anatomical tissue, reloaded with a second cinch optionally using the loader, and subsequently used to apply the second cinch to fix another portion of suture to fix the other portion of suture relative to anatomical tissue. The cinch is a unitary tubular member through which the suture can be advanced when the cinch is loaded within the applicator. The cinch defines multiple ribs and a cutter in a wall thereof. Operation of the applicator deforms the ribs inward to retain the cinch on the suture and displaces the cutter to sever the suture.

  • Patent number: 10398555
    Abstract: The diameter of an annulus in a patient (e.g., the mitral valve annulus) can be reduced using a tissue engaging member that is installed on the annulus and an actuator that is implanted into the patient's body. The tissue engaging member has anchors used to implant the tissue engaging member into the annulus, and a cinching loop runs through the tissue engaging member. The cinching loop terminates onto cinching wires. Preferably, tissue healing is used to enhance the bond between the tissue engaging member and the annulus. The actuator, which can be actuated from outside the patient's body, pulls the cinching wires in a proximal direction while holding the distal end of the cinching wires in close proximity to each other, so as to cause a reduction in the diameter of the cinching loop. This will cause a corresponding reduction in the diameter of the annulus.

  • Patent number: 10387021
    Abstract: A system is disclosed for performing hair transplantation procedures. The system may include a robotic arm and a tool coupled to the robotic arm, the tool configured for hair harvesting, site making or hair implantation. The system further includes a touch screen user interface that supports touch gestures for efficiently creating and manipulating objects, such as reserved regions, that control the harvesting, site making, and/or implantation sites selected by the system. The user interface implements logic rules that use the context in which a touch gesture is performed to determine the type of operation intended. The touch interface substantially eliminates or reduces the need for a user to use a keyboard or mouse during the procedure.

  • Patent number: 10369031
    Abstract: A delivery and release device for stent-graft includes a guiding head and a central tube connected thereto, an outer tube sleeving on the outside of the central tube, a positioning tube sheathed between the central tube and the outer tube, a front fixator, a back fixator and a positioner successively sheathed between the positioning tube and the outer tube. The stent-graft is placed between the back fixator and the positioner. A metal bar is connected to the guiding head along its axial direction with a ring suture being connected to the front fixator. The ring suture sleeves onto the metal bar after passing through the stent-graft. During the release process, the metal bar moves forward in the axial direction to detach from the ring suture, thereby the stent-graft is released.

  • Patent number: 10368902
    Abstract: A tissue-removing catheter includes a sensor configured to detect a parameter of the catheter during the cutting operation of the catheter when a tissue-removing element is in a tissue-removing position. A locking control circuit is in electrical communication with the sensor and a locking device. During an operational control function, the locking control circuit receives a signal from the sensor based at least in part on the parameter of the catheter detected during the cutting operation of the catheter. The locking control circuit determines whether the received signal is indicative of a tissue-removing element engaging a non-tissue obstruction. The locking control circuit configures the locking device in its locked configuration to inhibit movement of the tissue-removing element from its tissue-removing position to its neutral position if the received signal is indicative of the tissue-removing element engaging a non-tissue obstruction.

  • Patent number: 10342570
    Abstract: An apparatus, system and method for re-canalization or opening a passage through an occlusion in a blood vessel is provided. The apparatus and method, which are appropriate for cardiovascular and peripheral vessels, use a pulling member and a spring member, for example a compression spring, to oscillate a drilling component. The drilling component at the distal end of the catheter tip has combined longitudinal stiffness for penetrating a total or partial occlusion and high axial (lateral) flexibility to improve deliverability and crossability of a catheter through a partially occluded vessel or a tortuous vessel, and may taper distally. The system of the invention includes the apparatus and a control unit to permit adjustment of the frequency or amplitude of oscillation of the drilling component. Also provided is a method for oscillating a drilling component using a pulling member and a spring member and a method of traversing an occlusion.

  • Patent number: 10327743
    Abstract: The methods, devices, and systems are provided for performing endovascular repair of atrioventricular and other cardiac valves in the heart. Regurgitation of an atrioventricular valve, particularly a mitral valve, can be repaired by modifying a tissue structure selected from the valve leaflets, the valve annulus, the valve chordae, and the papillary muscles. These structures may be modified by suturing, stapling, snaring, or shortening, using interventional tools which are introduced to a heart chamber. The tissue structures can be temporarily modified prior to permanent modification. For example, opposed valve leaflets may be temporarily grasped and held into position prior to permanent attachment. In one aspect, a structure is deployed in a gutter region of the valve annulus to modify the shape of the valve.
