Abstract: A method and system for reducing and affixing two separated bone segments, the system having a bone plate with a pair of positioning slots, and a pair of elongated manipulating members with anchoring structures, the anchoring structures sized to pass through the positioning slots and for advancement into the bone segments. The bone plate is loosely mounted to the bone segments across the separation gap and a manipulating member is screwed into each bone segment through a positioning slot. The manipulating members are then used to reposition the bone segments by moving them together longitudinally within the slots. Fixation bone screws are inserted into the bone segments through screw receiving apertures to securely affix the bone plate to the repositioned bone segments. The manipulating members are then removed.

Abstract: A method of affixing a cranial burr hole cover comprising an elongated internal bracing member, a locking external cover member joined by one or more connecting members, and a locking mechanism, whereby the interior bracing member is tilted and one end is inserted through the burr hole and under the skull. The internal bracing member is then moved laterally relative to the burr hole to allow the opposite end of the internal bracing member to clear the opposite edge of the burr hole. The internal bracing member is then centered beneath the burr hole. The external cover member is now moved distally toward the skull to cover the burr hole. The locking mechanism secures the cover in place on the skull and the connecting members extending from the cover member are cut flush with the cover member.

Abstract: A cranial burr hole cover having a single, elongated internal bracing member, a locking external cover member joined by one or more connecting members, and a locking mechanism that precludes movement of the external cover member relative to the connecting members in the proximal direction once the cover is secured onto the skull. The internal bracing member is longer than it is wide. For a given burr hole, the cover will be chosen such that the longitudinal dimension is greater than the diameter of the burr hole and the width dimension is less than the diameter of the burr hole.

Abstract: A cranial implant molding device having a frame or base that receives a bottom or convex molding plate and a top or concave molding plate in a manner whereby the two plates are separated a distance to receive a settable or curable implant forming material therebetween. The plates are separated by a compressible member such that by the use of threaded mechanical fasteners or similar members the distance between the two plates can be adjusted by tightening or loosening the mechanical members. The thickness of the implant is varied by varying the separation distance on different sides of the frame.

Abstract: A cranial burr hole cover having an internal bracing member, a locking external cover member joined by one or more connecting members, and a locking mechanism that precludes movement of the external cover member relative to the connecting members in the proximal direction once the cover is secured onto the skull. The internal bracing member is longer than it is wide. For a given burr hole, the cover will be chosen such that the longitudinal dimension is greater than the diameter of the burr hole and the width dimension is less than the diameter of the burr hole. With this structure the interior bracing member of the burr hole cover may be inserted through the burr hole by tilting the internal bracing member such that a longitudinal end of the internal bracing member is able to be inserted into the hole and under the skull.

Abstract: A sternal closure clamp device for securing and retaining longitudinally divided halves of a sternum, and its method of use, the device having a pair of body members each having engagement members adapted to abut the sides of the sternal halves, and at least one rib extension member having rib retaining members and attached to at least one of said body members, such that the rib extension member can be secured to a rib to reduce the force being applied directly to the sternal halves.

Abstract: A sizable sternal closure clamp device for securing and retaining longitudinally or transversely divided halves of a sternum, the device having four body members and four engagement members that are positioned in inter-rib spaces on both sides of the sternum. The body members are interconnected in a sliding or telescoping manner that allows the device to be expanded or contracted in two orthogonal directions.

Abstract: A custom cranial repair implant is prepared by conforming a malleable sheet material, such as for example a thin metal foil, a polymer sheet material or a laminate of various materials, a formable cement or putty-like material, or a spray or liquid settable material, to the edges and depth of a cranial defect in a manner that creates a mold matching the cranial defect. The mold is removed from the cranial defect and a settable putty or cement material that is biocompatible is then poured into the mold and allowed to harden. Once sufficiently cured, the implant is then removed from the mold and further shaped if necessary by cutting, abrading or the like. The implant is then affixed within the cranial defect in known manner, such as by bonding, gluing, mechanical fasteners, etc.

Abstract: A sternal closure clamp device for securing and retaining longitudinally divided halves of a sternum, the device having four laterally extending engagement members that are positioned in inter-rib spaces on both sides of the sternum. The engagement members are connected to a centralized main body in a manner that allows the engagement members to be shortened or contracted such that the sternal halves may be pressed together and held in abutting relation. Each of the engagement members contracts in a direction non-perpendicular to the sternal incision, and the engagement members on a given side are non-parallel to each other such that device has a generally X-shaped configuration.

Abstract: A bone distractor having four bone plate attachment members for affixation to the posterior and anterior maxilla and/or zygomatic buttress and to the posterior and anterior mandible, the attachment members mounted onto a pair of parallel rods, one rod being a threaded drive rod and the other being a releasable guide rod, whereby rotation of the drive rod causes dimensional separation of the anterior attachment members from the posterior attachment members. The guide rod can be quickly removed such the superior attachment members joined to the maxilla and/or zygomatic buttress are physically separated from the inferior attachment members joined to the mandible such that the jaw can be opened.
