  • Publication number: 20170216015
    Abstract: Devices, systems, and methods to improve both the reliability of soft tissue repair procedures and the speed at which the procedures are completed are provided. The devices and systems include one or more tissue augmentation constructs, which include constructs that are configured to increase a footprint across which suture applied force to tissue when the suture is tied down onto the tissue. The tissue augmentation constructs can be quickly and easily associated with the repair suture, and can be useful in many different tissue repair procedures that are disclosed in the application. In one exemplary embodiment, one or more constructs are disposed on a suture threader, which can be used to associate the construct(s) with a repair suture(s) being used to repair the soft tissue. Tissue augmentation constructs can include various blocks and patches, among other formations. Exemplary methods for manufacturing the tissue augmentation constructs are also provided.

  • Patent number: 9693856
    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: 20170144173
    Abstract: A method provides for procuring platelet rich plasma (PRP) from a sample of whole blood in a vial. The method includes the steps of: separating the whole blood into layers through centrifugation with an upper layer containing platelet poor plasma (PPP) and a PRP layer below the upper layer containing PRP; adjusting an end point of a first range of motion of an extractor relative to a position of the PRP layer; moving the extractor through the first range of motion through the vial, PPP passing out from the upper layer through the extractor; and after the extractor reaches the end point of the first range of motion, extracting the PRP through the extractor and collecting the PRP.

  • Publication number: 20170000479
    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 on a first portion of at least a first limb and has a second portion connected to the filament engagement feature of the anchor. Preferably, at least one free filament limb, which in some embodiments is a length of the first filament and in other embodiments is a second filament, is capable of being passed through tissue to be repaired and has at least one end passable through the noose to enable incremental tensioning of the tissue after the anchor is fixated in bone. The noose strangulates the free filament limb when tension is applied to at least one of the free filament limb and the noose.

  • Publication number: 20160278761
    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: 20160166246
    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: 20160113758
    Abstract: Various bone anchor assemblies and methods are provided for anchoring tissue to bone. In one embodiment, an anchor assembly for anchoring a tendon to bone is provided and includes a substantially cylindrical sheath having bone-engaging surface features formed on an external surface thereof, and having an inner lumen formed therein and extending from an open proximal end to a substantially closed distal. The substantially closed distal end includes at least one tendon anchoring feature extending distally therefrom and configured to facilitate anchoring of a tendon to bone. The anchor assembly further includes an expander having a generally elongate cylindrical configuration and being sized and shaped to be received within the inner lumen of the sheath.
