  • Patent number: 10206786
    Abstract: The embodiments provide a spinal implant that is configured for lateral insertion into a patient's intervertebral disc space. The spinal implant may have a body having a tapered anterior portion and one or more apertures. The tapered anterior portion allows for concomitant distraction of soft tissue during insertion of the implant. In addition, at least some of the apertures are designed to permit a predetermined amount of nutation by a fixation element. The fixations elements that allow nutation enable the fixation element to toggle from one position to another, for example, during subsidence of the implant in situ.

  • Patent number: 10092405
    Abstract: The disclosure is directed to a resilient implant for implantation into human or animal joints to act as a cushion allowing for renewed joint motion. The implant endures variable joint forces and cyclic loads while reducing pain and improving function after injury or disease to repair, reconstruct, and regenerate joint integrity. The implant is deployed in a prepared debrided joint space, secured to at least one of the joint bones and expanded in the space, molding to surrounding structures with sufficient stability to avoid extrusion or dislocation. The implant has opposing walls that move in varied directions, and an inner space filled with suitable filler to accommodate motions which mimic or approximate normal joint motion. The implant pads the damaged joint surfaces, restores cushioning immediately and may be employed to restore cartilage to normal by delivering regenerative cells.

  • Patent number: 9282997
    Abstract: A growing rod for mounting between attachment mechanisms that are secured to anatomical structures of a patient having scoliosis. The growing rod includes a base rod having an attachment end, an extendable rod that is translatable relative to the base rod along a longitudinal axis and a housing enclosing at least a portion of the extendable rod therein. A magnet is rotatably mounted within the housing and is enclosed by a top magnet cover and a bottom magnet cover. The magnet includes a first pole and a second pole. A gear reduction mechanism is associated with the magnet and the extendable rod. The gear reduction mechanism reduces an output rotation to the extendable rod relative to an input rotation from the magnet.

  • Patent number: 9216016
    Abstract: A surgical device is disclosed which may advantageously perform the functions of both a retractor and a distractor. The device has two retractor blades facing each other and held in a common frame, the retractor blades are insertable into a surgical incision in a patient and moveable away from each other along a main axis (x) so as to widen the surgical incision; and a connecting pin attached at a distal end of each retractor blade. Each connecting pin is attachable to a pedicle screw anchored to respective vertebrae of the patient, so that moving away the two retractor blades along the main axis (x) determines a distraction of the vertebrae.

  • Patent number: 9216094
    Abstract: An elongate inserter has a distal end releasably connected to an expandable interbody fusion device and a proximal end including a trigger actuator. The interbody fusion device comprises a superior endplate and an inferior endplate that are movable in an expansion direction relative to each other in the intradiscal space. The device includes an elevator captively supported between the inferior endplate and the superior endplate for movement independently toward and away from each of the inferior endplate and the superior endplate. The inserter includes a lifting platform that defines lifting surfaces that upon operation of the trigger actuator cooperatively engage complementary lifting surfaces on the elevator and move the inferior endplate away from the superior endplate. A driver is supported by the inserter for pushing an insert into the expanded device between the superior and inferior endplates.

  • Patent number: 9211146
    Abstract: Devices, systems and methods for dynamically stabilizing the spine are provided. The devices include an expandable spacer or member having an unexpanded configuration and an expanded configuration, wherein the expandable member in an expanded configuration has a size, volume and/or shape configured for positioning between the spinous processes of adjacent vertebrae in order to distract the vertebrae relative to each other. The systems include one or more expandable members and a mechanical actuation means for expanding the expandable member or an expansion medium for injection within or for filling the interior of the expandable member via the port. The methods involve the implantation of one or more devices or expandable spacers.

  • Patent number: 9204973
    Abstract: An fusion cage having a longitudinal element and two planar bendable expansion arms slideably captured in a track on opposing sides, the expansion arms expandable from a pre-implantation position adjacent to the longitudinal element to a deployed position bounding an area around the longitudinal element in which bone graft material may be packed and retained after implantation into the intervertebral space. The longitudinal element is eliminated in favor of front and back lateral tracks in which the opposing ends of the expansion arms are slideably received so as to allow expansion of the bounded areas in both a lateral and anterior-posterior direction by sliding within the channels. Expansion of the area within the bendable members may be accomplished by rotation of leaves to which the bendable members are rigidly and slideably affixed.

  • Patent number: 9131965
    Abstract: A swellable, resilient interspinous implant is provided that includes a swellable polymeric medium, said polymeric medium being dispersed throughout the implant, the implant being dimensioned and configured to fit between two spinous processes of two adjacent vertebrae and buttress the space between the two adjacent vertebrae. In embodiments, the implant has a first configuration of reduced size such that it can be inserted into the patient in a minimally invasive manner. Once inserted to an application point within the patient, the implant expands in size to dynamically maintain the adjacent spinous processes in beneficial alignment. Also provided is a method of making a swellable, resilient interspinous implant as described herein. Also provided is a method of treating a degenerative condition of a spine which includes creating an incision and inserting, through the incision, between two spinous processes of two adjacent vertebrae, a swellable, resilient interspinous implant as described herein.

  • Patent number: RE46077
    Abstract: Support orthopaedic device (1) for a knee joint, comprising a proximal connector (2) and a distal connector (3), articulated among themselves and respectively intended to be associated with a proximal bone (100) and a distal bone (101) of a lower limb connected among themselves by a knee joint. The device comprises a first rod (4a) and a second rod (4b), which are hinged, according to hinging axes normal to a median excursion plane of the orthopaedic device (1), to the proximal connector (2) and to the distal connector (3) so as to form with them an articulated quadrilateral. The articulated quadrilateral is planarly mobile according to a plane parallel to the excursion plane between a configuration corresponding to an extended position of the knee joint and configurations corresponding to bendings of different entity of the knee joint; the relative motion imposed to the proximal and distal connectors (2, 3) by the articulated quadrilateral is consistent with the physiological movement of the knee joint.
