  • Patent number: 9980735
    Abstract: Devices, systems, and methods are provided for facilitating the aligning and balancing of the knee during total knee replacement surgery. A femoral assembly is engaged with a distal femur. The positions of medial and lateral portions of the femoral assembly relative to a stationary portion of the femoral assembly can be separately adjusted to adjust the alignment of the knee. A force sensor will be provided to sense the forces in the medial and lateral portions of the knee, and the medial and lateral portions of the femoral assemblies will be adjusted so that the sensed forces are balanced. The alignment of the knee is visually verified using a knee alignment verification member coupled to the femoral assembly. The knee alignment verification member may emit laser beams along the mechanical axes of the femur and tibia, or the knee alignment verification member may couple to alignment rods aligned along these axes.

  • Patent number: 9974577
    Abstract: A spinal procedure includes attaching a first reduction instrument to a first guide assembly and a second guide assembly. The first reduction instrument includes a fixed attachment assembly and a translating attachment assembly that cooperatively interfaces the fixed attachment assembly. The first guide assembly is attached to a first pedicle and the second guide assembly is attached to a second pedicle. The first reduction instrument is moved to reduce an orientation of the spine, while imaging a reduction of the orientation of the spine. An angle and position of the first reduction instrument is locked upon achieving a desired reduction. The spine may then be fused.

  • Patent number: 9956091
    Abstract: A method for inserting an intervertebral disc prosthesis into a space between two vertebrae involves inserting the prosthesis partway into the space under constraint to prevent endplates of the prosthesis from articulating, releasing the prosthesis from constraint, and inserting the unconstrained prosthesis farther into the space. In some embodiments, the method involves grasping the prosthesis with a grasping device to insert the prosthesis partway under constraint, loosing the grasping device to release the prosthesis from constraint, and pushing the prosthesis farther into the disc space using the grasping device and/or one or more separate pusher devices. A system includes a grasping device, at least one separate pushing device, and optionally a vertebral spreading device and/or a vertebral midline indicator device.

  • Patent number: 9937052
    Abstract: A delivery device for inserting an interbody implant into an intervertebral space in a patient has an elongate tube with a channel and is sized to fit in an intervertebral space. The elongate tube has a proximal portion, a distal portion, a longitudinal axis, and a window with a longitudinal axis. The window is disposed adjacent the distal portion of the elongate tube and the longitudinal axis of the window is offset from the longitudinal axis of the elongate tube. The channel is sized to receive the interbody implant, and also the channel is configured such that the interbody implant is advanced therealong from the proximal region toward the distal region. The interbody implant is deployed into the intervertebral space from the window.

  • Patent number: 9918755
    Abstract: An apparatus for dispensing a plurality of implants including a barrel, a magazine, and a driver. The barrel has a longitudinal passage and a lateral passage intersecting the longitudinal passage adjacent a distal end of the barrel. The magazine has a housing defining a chamber for holding a plurality of implants. The housing is slidably connected to the barrel and movable between a retracted position and an extended position wherein a slot of the housing is aligned with the lateral passage of the barrel. A pusher member connected to the housing is caused to push one of the implants through the slot and the lateral passage and into the longitudinal passage. The driver is disposed in the longitudinal passage to be axially and rotatably movable to apply a rotational force to the implant.

  • Patent number: 9895176
    Abstract: A method for fusing a spinal sacroiliac joint and a surgical kit. The kit includes a bone-void filler, stabilization device or implant, a guide pin, a joint locator, a set of dilation tubes, a reamer, a novel directional cannula, a novel tapping cap, a novel drill guide, a drill bit, and a novel implant positioner. The method includes the steps of locating the sacroiliac joint, retracting the soft tissue exposing the graft site, removing any bone obstructions and preparing a relatively smooth graft site horizontal to the immediate sacroiliac joint, creating a cavity in the ilium and sacrum to a predetermined depth that spans the sacroiliac joint, inserting a novel stabilization implant into the cavity, and seating the implant within the cavity at a predetermined depth.

  • Patent number: 9889016
    Abstract: Disclosed is an implantable artificial intervertebral disc joint replacement device for implantation between adjacent vertebral bodies. The device allows selective positioning of a disc implant element and comprises translatable surfaces, a mechanism for translation, a means for bone attachment, and an integrated disc implant. The device can be used in the lumbar, thoracic, and cervical regions of the spine in single or multi-level configurations. When implanted in a patient, the device includes an upper (cranial) component and a lower (caudal) component attached to the vertebral body above and below the replaced intervertebral disc respectively, with the joint implant integrated into the translatable surfaces. Following implantation, precise positioning of the joint implant within the intervertebral space with respect to the spinal axis is then adjusted based upon the particular anatomical and functional needs of the individual patient to satisfy spinal range of motion and stability requirements.

  • Patent number: 9770302
    Abstract: A method for performing an open wedge osteotomy includes providing a fixation plate defining a first aperture and a second aperture and creating a first hole and a second hole in a bone. The fixation plate is coupled to the bone by aligning the first aperture of the fixation plate and the first hole of the bone and inserting a fastener through the first aperture and into the first hole. A cut is created through at least a portion of the bone to create a first resected surface and a second resected surface after creating the first hole and the second hole. The method further includes moving the first resected surface and the second resected surface relative to each other until the second aperture of the fixation plate is aligned with the second hole of the bone. The fixation plate is coupled to the bone by inserting a second fastener through the second aperture of the fixation plate and into the second hole of the bone.
