Internal Fixation Means Patents (Class 606/60)
  • Patent number: 10363140
    Abstract: The present invention relates generally to implants and tools for the fixation or fusion of joints or bone segments. These tools include tissue dilators and protectors. Other tools include broaches used to shape bores in bone. The tools can also include a system for removing an implant from bone. Implants can include assemblies of one or more implant structures that make possible the achievement of diverse interventions involving the fusion and/or stabilization of lumbar and sacral vertebra in a non-invasive manner, with minimal incision, and without the necessitating the removing the intervertebral disc. Implants for fusing both sacroiliac joints of a patient include a long implant that extends across both sacroiliac joints.

  • Patent number: 9398925
    Abstract: Correction of a scoliotic curve in a spine comprises the steps of implanting an expanding rod isolated completely under the skin and attached to selected portions of the scoliotic curve of the spine at opposing ends of the rod; and producing a controlled force by means of expansion of the rod over at an extended time period under external control until a desire spinal curve is obtained. An incremental force is generated to stretch the scoliotic curve of the spine between the selected portions where attachment of the rod is defined. The controlled force is provided steadily for at least one month or alternatively 1-3 months. Multiple rods may be employed each associated with a different scoliotic curve of the spine or a different portion of the scoliotic curve.

  • Patent number: 9295508
    Abstract: Embodiments provide a method and device for plate osteosynthesis of a bone fracture that allows angle-stable fixation of the bone fracture, while permitting elastic axial motion at the fracture site in a controlled, symmetric manner to stimulate fracture healing. Embodiments pertain to a bone plate having an outer surface and a bone-facing surface. The bone plate incorporating internal sliding elements containing a threaded receiving hole for bone screws that have a correspondingly threaded screw head. The sliding elements undergo controlled displacement parallel to the longitudinal axis of the plate but are substantially constrained against displacement perpendicular to the longitudinal axis of the plate. The bone screws with threaded heads may be rigidly fixed to the threaded receiving holes in the sliding elements without compressing the bone plate onto the bone surface. Sliding elements are elastically suspended inside the bone plate and undergo dynamic motion.

  • Patent number: 9289248
    Abstract: An assembly for distraction of spinal vertebrae and which can optionally accommodate retraction blades. The assembly includes a pair of pins each having a first end adapted for vertebral bone engagement and a second end. A pair of sleeves respectively and concentrically engage said pins. A frame includes respective openings which receive the pins and a first end of each said sleeves. The first end of each said sleeve including a portion offset relative to a longitudinal axis of said sleeve such that when the first end of each said pins is anchored in bone, axial rotation of each said sleeves enables said first end of each said pins to move between a first position in which said vertebral bones are not distracted and a second position in which said vertebral bones are distracted.

  • Patent number: 9248007
    Abstract: According to an aspect of the invention, in a set of male dental components, such as abutment screws, each male dental component has a threaded portion with different core diameter. Each male dental component is to be connected to a mating female dental component, such as an abutment. The smaller core diameter a threaded portion has, the higher friction is provided when the male dental component is finally tightened to its mating female dental component, even though the same insertion torque is applied to all male dental components.

  • Patent number: 9204898
    Abstract: A coupling device for securing an elongate member to the spine is provided. The coupling device comprises a compressible inner member that secures an anchor member therein when the inner member is axially shifted within an outer member. The elongate member is retained within the device by an axially inserted locking member, and may be secured independently of the anchor member. The coupling device and anchor may be configured to provide increased angulation of the anchor with respect to the coupling device. For instance, anchor member may have an offset head portion in order to provide normal pivoting of the coupling device when the anchor is attached to bone at an angle.

  • Patent number: 9204874
    Abstract: A method and apparatus for bunion repair using a suture passing K-wire configured to easily pass through bone tunnels with suture trailing. The suture passing K-wire includes a tapered guide pin with a multi-diameter shaft (i.e., comprising at least two regions or sections that have different diameters) and a loop which is securely attached to an end of the guide pin (i.e., to the smaller diameter section of the guide pin). The reconstruction system may be formed of a pair of buttons connected by a flexible strand. The procedure offers indirect placement of buttons and a minimally invasive approach.

  • Patent number: 9179937
    Abstract: The present invention generally is directed toward a spinal fixation system whereby a coupling element allows the physician to selectively lock or unlock either the connection between the coupling element and a fastener, such as to allow for repositioning of the coupling element, or the connection between the coupling element and an elongate rod. The locking or unlocking of these connections may be made independently and as desired by the physician.

  • Patent number: 9179950
    Abstract: An adjustable, knotless button/loop construct for fixation of ankle syndesmosis tibio-fibular diastasis and an associated method of ankle repair using the same. The knotless construct comprises a pair of buttons attached to a flexible, continuous, self-cinching, adjustable loop integrated with two splices that are interconnected. The knotless construct is passed through fibular and tibia tunnels and the buttons are secured on the cortical surfaces of tibia and fibula. One of the buttons (for example, an oblong button) is secured on the medial side of the tibia by passing the button and the flexible, adjustable loop though the fibular and tibia tunnels and then flipping and seating the button outside the tibia. The length of the flexible adjustable loop is adjusted so that the second button (for example, a round button) is appropriately secured on the lateral fibula.
