  • Patent number: 11382616
    Abstract: Described herein are systems and methods for securing sutures that obviate the need for tying knots. Instead of tying two ends of a suture or two sutures together with a knot, two or more suture portions can be fused or cauterized together using heat. A device can be applied to adjacent suture portions that heats the suture portions and causes the suture portions to fuse together, effectively securing the suture portions together without a knot. Such devices can include a shaft, a heating element positioned within the shaft, and a suture holder at the distal end of the shaft. The holder in an open position receives sutures and in a closed position holds the sutures. Actuation of the device causes the heating element to apply heat and fuse together sutures held by the holder. The holder can separate from the fused sutures after the sutures are fused together.

  • Patent number: 11178861
    Abstract: A tool for feeding a fishing line through the eyelets of a fishing rod has a loop of filament attached to an elongated guide and twisted across itself at a distal overlap to form a figure-eight with proximal and distal portions wider and narrower, respectively, than the eyelets. The wider portion facilitates insertion of a free end of the line into the loop. The loop is resiliently flexible so that the overlap separates and then recovers as the inserted line is passed transversely through the gap into the narrower portion of the figure-eight. The passed line is then transversely wedged in the narrower portion of the figure-eight. The loop is also resiliently flexible so that, as the guide leads the loop and the line through each eyelet, the wider portion of the loop compresses and then expands, inhibiting inadvertent withdrawal of the tool from an eyelet.

  • Patent number: 10918379
    Abstract: A suturing device includes a needle, a suture, an elongate body, an actuator and a needle holder. The suture connects with the needle. The needle holder extends away from a distal end portion or is provided as part of the distal end portion of the elongate body. The needle holder includes a distal end section having a distal-most tip, and defines a needle passage for holding the needle and a distal opening. At least a portion of the suture extends through the distal opening when the needle is received in the needle passage and the actuator is in a first operating position. At least a portion of the suture extends along the needle passage toward the distal opening between the needle and an inner surface of the needle holder when the needle is received in the needle passage and the actuator is in the first operating position.

  • Patent number: 10888312
    Abstract: A suture securing assembly comprises a two-bodied anchor and an associated delivery system which enhances fixation of a micro anchor in a bone hole or tunnel, as well as improving suture lock within bone. Initially, the two bodies are separated by a length of an inner shaft of the delivery system. The proximal body is fixed on the inner shaft of the delivery system and cannot move relative to the handle until after insertion into the bone, when the delivery system is disengaged from the anchor. The distal body further includes expansion wings and/or other features for increasing suture lock within the bone hole.

  • Patent number: 10888314
    Abstract: A suturing device includes a curved needle, a suture, an elongate body, an actuator and a curved needle holder. The suture connects with the curved needle. The actuator is operable between a first operating position and a second operating position. The curved needle holder extends away from a distal end portion or is provided as part of the distal end portion of the elongate body. The curved needle holder includes a distal end section having a distal-most tip. The curved needle holder defines a curved needle passage and a distal opening. Movement of the actuator from the first operating position toward the second operating position moves the curved needle with respect to the curved needle holder toward a released condition. The distal end section is configured to allow the curved needle to release from the curved needle holder at a location offset from the distal-most tip.

  • Patent number: 10874388
    Abstract: Anchor delivery systems and methods for repairing a valve inside a body, such as an atrioventricular valve, may include an anchor delivery device including a sheath for at least partially retaining an anchor in a collapsed form. The anchor delivery device may be configured to deliver the anchor to the atrioventricular valve. The anchor and an adjacent anchor may be connectable to each other in an expanded form, to link a series of anchors implanted at least partially around the atrioventricular valve. In some embodiments, the anchors may be connectable by a connecting member, such as a pledget, or a material disposable on a bulb of the anchor. In other embodiments, a bulb of the anchor and a bulb of the adjacent anchor may be configured to be directly interlocked.

  • Patent number: 10849616
    Abstract: Surgical constructs, assemblies and methods for tissue reinforcement with a reinforcement (reinforcing) material such as suture, tape, weave, ribbon or mesh, among many others. The reinforced construct includes a reinforced section that prevents a suture from pulling apart. The reinforced section is be a piece of material (a reinforcement or reinforcing material) such as reinforced stitched suture tape attached to a flexible strand. A needle attached to the flexible strand terminating with the reinforced section passes through a proximal end of the reinforced section to form an adjustable “starter loop.” The starter loop is slid and positioned over tissue (for example, graft, tendon, ligament, etc.) and the suture is pulled apart to tighten the loop around the tissue.
