  • Publication number: 20200022732
    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: 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.

  • Publication number: 20190328928
    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.

  • Publication number: 20190216519
    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: 20150138580
    Abstract: Methods and systems establish dynamic profiles for each of many document processing devices, based on current device connection specifications, current device drivers, current device capabilities, and current device workflow functions using a centralized connection device. These methods and systems provide device menu options from the centralized connection device to graphic user interfaces of the document processing devices. The device menu options provided from the centralized connection device displays the graphic user interfaces for the control of the document processing devices with the currently available workflows (that will be processed using a corresponding device and at least one other device of the document processing devices) and currently available management functions for the corresponding device and the other device(s) of the document processing devices. The “corresponding” device corresponds to the specific one of the graphic user interfaces receiving input to the device menu options.

  • Patent number: 8337527
    Abstract: A spinal connector includes a first seat having a first opening for coupling to a first spinal connecting member along a first longitudinal axis and a second seat having a second opening for coupling to a second spinal connecting member along a second longitudinal axis. The second longitudinal axis is substantially coaxial to the first longitudinal axis for connecting the first and second connecting members end to end. The spinal connector also includes a ball enclosure rotatably received in the second opening of the second seat. The ball enclosure defines a bore along the second longitudinal axis and articulates with the second opening for allowing change of orientation of the second connecting member relative to the first connecting member.
