  • Publication number: 20220087673
    Abstract: Methods of tissue repair. At least one example method includes: pulling a tissue in place over a bone location; abutting a distal end of a guide tool against the tissue at a first location, and driving a first bone anchor through a delivery tube of the guide tool, through the tissue, and into the bone at the first location, the first bone anchor coupled to a first suture line; abutting the distal end of the guide tool against the tissue at a second location displaced from the first location, and then driving a second bone anchor through the delivery tube, through the tissue, and into the bone at the second location, the second bone anchor associated with the first suture line; withdrawing the guide tool away from the tissue; and tightening the first suture line to create a first suture over the tissue.

  • Patent number: 11219444
    Abstract: A surgical device includes a first fastener having a planar profile, a second fastener having a concave surface, and a suture that can be manipulated to change a distance between the first and second fasteners. The second fastener has a curvature that substantially matches the curvature of a top surface of a clavicle bone in a direction perpendicular to a long axis of the clavicle bone. A method of treating an acromioclavicular joint injury includes forming axially aligned passages through a patient's clavicle and coracoid process, passing a fastener having a concave surface through the passages, positioning the concave surface of the fastener against a top surface of the patient's clavicle with a long axis of the fastener extending perpendicular to a long axis of the clavicle, positioning a fastener having a planar profile below the patient's coracoid process, and adjusting a suture that couples the fasteners.

  • Publication number: 20210259677
    Abstract: Guide tools for installation of fixation devices. At least one example embodiment includes: a delivery tube, the delivery tube defines a slot that runs from the distal end to the proximal end; a guide tube coupled to the delivery tube; and a handle coupled to the proximal end of the delivery tube and coupled to the proximal end of the guide tube. The handle may include a first channel into an interior of the delivery tube through the slot, and a receptacle in operational relationship to the delivery tube and the first channel.

  • Publication number: 20210177436
    Abstract: Apparatuses and methods for microfracture (e.g., forming a plurality of microfractures in a bone to encourage cartilage regeneration). Some of the present apparatuses and methods are configured to create microfractures with smaller transverse dimensions (e.g., diameters) and greater depths than previously known. Some of the present apparatuses and methods comprise a penetrator removal tab coupled to the penetrator and configured to retract the penetrator relative to the cannula.

  • Publication number: 20200367912
    Abstract: Microfracture apparatuses with a cannula and a penetrator. The cannula has a first end, a second end, and a channel extending between the first end and the second end through which a penetrator can move between a retracted and an extended position substantially without rotation of the penetrator. The cannula has a primary portion and a distal portion between the primary portion and the second end, with the distal portion configured such that the distal portion and/or the second end of the channel is disposed at a nonparallel angle relative to the primary portion, for example, with a curve between the primary portion and the distal portion. The penetrator is configured to flex around such a curve and/or to flex to align with the angle of the send end of the channel and/or the distal portion of the cannula.

    Abstract: A fixation device. At least one example embodiment is a bone anchor comprising: a proximal head; a bollard coupled to the proximal head; a first barb coupled to the bollard, the first barb extends outward a first distance measured perpendicularly from an anchor central axis, the first distance greater than half the transverse dimension of the bollard, and the first barb extends outward at a first radial from the anchor central axis; and a second barb coupled to the first barb, the second barb extends outward a second distance measured perpendicularly from the anchor central axis, the second distance greater than half the transverse dimension of the bollard, and the second barb extends outward at a second radial from the anchor central axis, the second radial at a second rotational orientation at least 36 angular degrees from the first radial.
