  • Patent number: 10004495
    Abstract: Methods and devices are provided for anchoring suture to tissue, incorporating anchoring devices constructed substantially from suture. The anchoring devices are constructed as longitudinally extended, preformed knot configurations that upon deployment are reconfigured to form anchoring knots having an increased cross-section relative to the preformed knot configuration, for secure lodging in tissue. The anchoring devices are suitable for single and multi-anchor surgical procedures in soft tissue or bone, and multiple anchors can be delivered using a single delivery device.

  • Publication number: 20180161027
    Abstract: Methods and devices are provided for anchoring suture to bone. In one embodiment, an elongate weave of fibers can be provided having a first portion with a first pick count and a second portion with a second pick count that is greater than the first pick count. The first portion can have a cross-section that deforms in response to a force that is applied thereto. The first portion can have a collapsible diameter and can have a bending stiffness that is lower than a bending stiffness of the second portion of the suture. The first portion can also have a first pattern that is different than a second pattern on the second portion of the suture. The first portion can be threaded into a suture anchor such that it can be doubled over upon itself. The present invention also provides exemplary sutures and drivers that can be used with the various methods and devices disclosed herein, or with other methods and devices known in the art.

  • Publication number: 20180140292
    Abstract: A surgical filament snare assembly including an anchor capable of being fixated in bone and having a filament engagement feature. A first filament has a noose with first and second noose limbs connected, preferably slidably connected, to the filament engagement feature of the anchor. The first and second noose limbs emerge from the anchor as first and second free filament limbs which are capable of being passed through tissue to be repaired and then passable through the noose. The noose, such as one or more half-hitches, is capable of receiving the free filament limbs and strangulating them when tension is applied to at least one of the free filament limbs and the noose to enable incremental tensioning of the tissue after the anchor is fixated. Preferably, the snare assembly further includes a flexible sleeve joining at least some portion of the first and second free filament limbs to facilitate passing of the free filament limbs at least through the tissue as a single unit.

  • Publication number: 20180098803
    Abstract: Various exemplary methods, systems, and devices for blood flow are provided. In general, an implant can be configured to be implanted in bone and to delay clotting of blood flowing from the bone. The implant can include an anti-coagulation agent to delay the clotting of the blood. The anti-coagulation agent can be a coating on the implant, can be natural to a material forming the implant, or can be impregnated into a material forming the implant. In an exemplary embodiment, the implant is implanted in a bone in a surgical procedure for securing a soft tissue to bone, such as a rotator cuff repair procedure or an anterior cruciate ligament (ACL) repair procedure.

  • Patent number: 9931194
    Abstract: Methods and devices are provided for fixing a ligament graft in a bone tunnel. In general, the methods and devices involve affixing a ligament graft within a bone tunnel using an adhesive. A fixation device can be inserted through the ligament graft in a direction transverse to an axis of the tunnel to maintain the ligament graft in contact with the adhesive. The fixation device can be removed when the adhesive is cured such that the ligament graft is fixed in the tunnel.

  • Publication number: 20180028203
    Abstract: A system and method for attaching tissue to bone are provided. In one embodiment, a system for attaching tissue to bone includes a suture, suture anchor, inserter tool, drill, and drill guide having an outer guide and an inner guide. A method for attaching tissue to bone includes attaching a suture to tissue, nesting the suture in a notch on the distal end of the outer guide, passing the suture through a lumen formed in the outer guide, and inserting an inner guide in a lumen formed in the outer guide. The drill guide protects the suture from rotational movement of the drill and allows a user to maintain alignment between the drill guide and the drilled hole. As a result, a suture anchor can be more easily positioned within the drilled hole.

  • Publication number: 20170303913
    Abstract: Surgical constructs and methods are provided for securing soft tissue to bone. One exemplary embodiment of a construct is formed from a suture filament and includes two terminal ends of filament and an intermediate portion disposed along at least a portion of a length extending between the terminal ends. The construct can have a first terminal end that is the first terminal end of the filament, and a second terminal end that includes a loop. The loop can be formed by disposing the second terminal end of the filament within a volume of a portion of the intermediate portion of the filament. In some disclosed methods, both terminal ends of the filament can be passed through tissue when performing soft tissue repairs. Various other embodiments of constructs and methods are provided, including constructs having two or more filaments associated with an anchor and methods of using such constructs.

  • Publication number: 20170265988
    Abstract: Methods and devices are provided for anchoring a ligament or tendon to bone. In general, various inserter tools are provided for simultaneously delivering an expandable sheath and an expander into bone. With both components of the implant mounted on the same tool, the sheath and a ligament can be advanced into a bone hole and the expander, which trails behind the sheath during delivery of the sheath, can be advanced into the sheath to expand the sheath and anchor the sheath and ligament within the bone hole.

  • Publication number: 20170252086
    Abstract: In general, devices, systems, and methods for driving an anchor into bone are provided. In one embodiment, a surgical tool is provided that includes a driver tool with a handle and an elongate shaft. A resistance element is disposed within the handle. An inner portion of an anchor is retained on a distal end of the elongate shaft, and a guidewire extends between the resistance element and an outer portion of the anchor that is in bone. As force is applied distally to the handle, the guidewire pushes the anchor into the bone before overcoming force of the resistance element and thereby allowing the inner portion of the anchor to be driven into the outer portion of the anchor.
