  • Patent number: 11311323
    Abstract: An apparatus is provided for fusing bones of the human body. The apparatus comprises a bone plate which generally is a member having one or more fixation apertures, configured to receive fasteners, and an insert aperture. The bone plate comprises a semi-rigid material, such as a biocompatible metal or Polyetheretherketone (PEEK), possessing a tensile strength suitable for immobilizing bones. A convertible insert is configured to be retained within the insert aperture. The convertible insert is configured to optimally direct a fastener towards a chosen point of purchase for fixating or compressing bones. In some embodiments, the insert is configured to direct a fastener at an oblique angle relative to a plane of the fusion plate. In some embodiments, the insert is configured to direct a fastener at a substantially right angle relative to the fusion plate.

In use, distal ends of the shafts can be fixed or constrained relative to one another and to an implant such that the counter torque shaft cannot orbit around the driver shaft. Rotating the handle can rotate the driver shaft, driving the implant. This can cause the counter torque shaft to try to orbit around the driver shaft, but the fixed/constrained ends restrict this motion, applying the counter torque.

  • Patent number: 10631898
    Abstract: A spinal stabilization system generally comprises first and second anchor members configured to be secured to first and second vertebrae within a patient's body, a flexible element secured to the first anchor member, and a rigid element secured to the second anchor member. An end portion of the rigid element is coupled to an end portion of the flexible so that the system is able to provide both rigid and dynamic stabilization. The coupling is maintained even if the flexible element relaxes after a period of time within the patient's body.

  • Patent number: 10595910
    Abstract: Disclosed is a dynamically stabilizing intervertebral implant composed of a stabilizing wedge (1), a blocking pin (2), a locking screw (3), and a flexible link in the form of a strap. The stabilizing wedge includes a recess (12) through which the strap can pass. The blocking pin can come into engagement with the wedge by movement inside the recess in the direction of the main axis of the body of the wedge in such a way that the longitudinal axis of the blocking pin firstly coincides with the longitudinal axis of the recess, secondly is perpendicular to the longitudinal axis of the first strap portion inside the recess, and thirdly is parallel to the surface of the first strap portion inside the recess. The strap is immobilized with respect to the stabilizing wedge by being clamped between the blocking pin and the inner wall of the recess.

  • Patent number: 10588668
    Abstract: An articulating assembly includes a first elongated element for attachment to a first anatomical region, and a second elongated element for attachment to a second anatomical region. In at least one embodiment, a coupling connects the first and second elongated elements. The coupling includes a moveable joint configured to allow polyaxial movement of the first elongated element with respect to the second elongated element. The assembly further includes a locking mechanism. The locking mechanism is operable in an unlocked condition to permit polyaxial movement of the first elongated element with respect to the second elongated element, and a locked condition to immobilize the movable joint and fix the position of the first elongated element with respect to the second elongated element.

  • Patent number: 10548638
    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: 10548775
    Abstract: A bioabsorbable tissue support is inserted into a tissue of a subject during, or after, puncture of the tissue. The bioabsorbable tissue support includes a material that is gradually absorbed into the punctured tissue in time, and disappears. The bioabsorbable tissue support may be inserted standing alone, or in association with a permanent or temporary non-bioabsorbable tissue support, may define the shape of the punctured hole, and/or may release useful or ornamental chemicals into the punctured tissue. The chemical may include an antibacterial material, an antifungal material, an antimicrobial material, topical anesthetic, a temporary or permanent dye material, and/or an antiproliferative agent. The non-bioabsorbable tissue support may include a self-expanding material that enlarges the size of the puncture in time. The bioabsorbable tissue support may have the form of a tube and/or a mesh of variable peripheral shapes, be elongated, and/or have attachable and detachable end plates and pointed tips.
