  • Publication number: 20240207485
    Abstract: The present disclosure provides citrate-based constructs for use in the repair of osteochondral defects. The constructs generally include: (i) a citrate component, (ii) a diol component, (iii) a polyol, and (iv) particulate inorganic material. The scaffold may take the form of a 50-90% porous scaffold and may form a polymer network. The scaffold may be soaked in a hyaluronic acid solution and may be freeze-dried to produce a porous construct within the pores of the scaffold. The scaffold may be biphasic, containing a porous section for subchondral bone regeneration and a citrate-based polymer hydrogel for cartilage regeneration. The scaffold may form an implant and the implant may include an inner porous core of a biphasic core-shell construct.

  • Publication number: 20240197966
    Abstract: A patch system and method for musculoskeletal repair is provided, the patch system including a patch that defines a patch thickness, the patch fabricated, in whole or in part, from a composition that includes a citrate polymer and a bioceramic filler, and wherein the patch defines a porosity gradient across the patch thickness. The patch may be defined by a plurality of patch layers, e.g., patch layers formed from a plurality of fibers, and first fibers associated with a first patch layer are non-aligned relative to second fibers in a second, adjacent patch layer.

  • Publication number: 20240156586
    Abstract: Graft tensioning systems and associated engagement assemblies are provided. The engagement assemblies include at least one engagement element or foot that is configured to engage with tissue adjacent or opposed to an implant-receiving opening. The engagement element(s) support stable interaction between the graft tensioning system and the anatomical target region, while reducing the potential for tissue bruising/trauma/contusions. The engagement elements may be interchangeably mounted relative to the graft tensioning device, e.g., intraoperatively, to permit a surgeon to select an engagement element offering desired properties for the specific procedure and/or anatomical properties of the patient.

  • Patent number: 11684467
    Abstract: The present invention provides an anchor system for musculoskeletal applications, e.g., for anchoring tendons or ligaments to bone or anchoring two or more bone sections. The anchor system comprises a substantially solid pre-manufactured distal portion (i.e., anchor component) and a settable, biodegradable composite. The biodegradable composite is flowable at the time of delivery and is introduced into the fixation site before or after the anchor component. Both the anchor component and the biodegradable composite may be manufactured from citrate-based polymers.

  • Patent number: 11285241
    Abstract: Disclosed is a medical device having a substrate having an exposed surface and a texture over at least part of the exposed surface. The texture includes a plurality of nanofeatures that inhibit bacterial adhesion on the surface and that also inhibit bacterial growth on the surface and have a size range between about 0.01 nanometers and about 1,000 nanometers. The texture can include a plurality of nanofeatures applied thereto such that the texture has a first particle size at a first location, a second particle size at a second location, and a gradient of particle size from the first particle size to the second particle size between the first location and the second location.

  • Patent number: 11234741
    Abstract: The present teachings provide one or more surgical implements for repairing damaged tissue, such as through a fixation procedure. A system for a percutaneous procedure is provided. The system can include a bone fastener including a receiver. The system can include a device having a first end, a second end and a middle portion. The first end, middle portion and second end can be disposed along a longitudinal axis, and the second end can be connected to the receiver. The middle portion can have a pair of deformable leg members extending between the first and second ends. The leg members can define a channel having a width. The leg members can be selectively movable between a retracted state and an expanded state with the width of the channel greater in the expanded state than in the retracted state.

  • Publication number: 20210196448
    Abstract: The present disclosure provides advantageous interference anchor. More particularly, an advantageous tendon interference anchor configured to be inserted through impaction. The tendon interference anchor may include an anchor body having a proximal end, distal end, longitudinal axis, and an outer surface and at least one protrusion extending outwardly from the outer surface of the anchor body in a direction non-parallel to the longitudinal axis of the anchor body.

  • Patent number: 10980589
    Abstract: An orthopedic implant screw driver includes drive shaft. A first gear is operably coupled to the drive shaft and in meshing engagement with a hollow gear which rotates in response to rotation of the drive shaft. The hollow gear includes a passage defining an inwardly facing screw engagement periphery configured to receive and drivingly rotate a threaded portion of the screw. A method of securing an orthopedic implant to a bone includes positioning a screw within the passage which is configured to drivingly engage a threaded portion of the screw and rotating a drive shaft in driving engagement with the gear causing the gear to engage the screw along the threaded portion of the screw and rotatably drive the screw via the threaded portion.

  • Publication number: 20200000574
    Abstract: Biodegradable and bioabsorbable anchors and anchor systems for use in musculoskeletal fixation applications comprising (1) an anchor body comprising a longitudinal axis, a proximal end, a distal end, an outer surface, and a bore extending from the proximal end and parallel to the longitudinal axis, wherein the bore defines an inner surface of the anchor body, and wherein at least a portion of the anchor body is expandable in a direction non-parallel to the longitudinal axis, and (2) an expansion pin comprising a longitudinal axis, a proximal end, a distal end, and a surface, and configured for insertion into the bore such that, when inserted, it expands the expandable portion of the anchor body in a direction non-parallel to the longitudinal axis. Both the disclosed anchors and anchor systems are at least in part formed from a citrate-based polymer.
