  • Publication number: 20100152738
    Abstract: An abrading device consists of an advanced burr and appliqué for a burr and a new process for making cutting tools for fine material removal applications such as in bone and tissue surgeries. An appliqué sheet is first engineered by CAD with an abrading surface having cutting facets. The appliqué is attached to a surface of a tool blank and then metallurgically bonded and coated by the BRAZOL® or Co—P process. The tool blank has a proximal shank attachable to a driver and a distal surface to which the appliqué is affixed. Since each facet is attached to surrounding facets and then strongly bonded to the tool, the facets do not dislodge when used to abrade a surface of an object. The BRAZOL® or Co—P coating imparts excellent wear resistance and lubricity to the cutting facets. This results in excellent operational and material removal characteristics. This approach to making surgical and fine industrial tools offers engineered flexibility in design rather than process dependent designs.

    Abstract: A method for forming an acetabular shell includes providing a working surface such as a mandrel, and spraying the working surface with a first layer of material having a first composition such as aluminum oxide. After a suitable thickness is generated, the spray composition is gradually changed to other compositions having desired particle sizes and distribution. In one example, the composition is changed to a mixture of aluminum oxide and titanium oxide and/or titanium. As thickness builds up, the relative amount of aluminum oxide is decreased such that the composition is all titanium and titanium oxide. After a desired thickness is generated, the acetabular shell is extracted off the mandrel.

    Abstract: To change a spatial relationship between two or more bones in a patient's body, a wedge member is moved into a joint between the bones. As the wedge member enters the joint, pivotal movement occurs between the bones to change the orientation of the bones relative to each other. The wedge member may have a circular cross sectional configuration and be moved into the joint by rotating the wedge member about an axis which extends between a thin leading edge portion and a thick trailing edge portion of the wedge member. Alternatively, the wedge member may have a cam-shaped configuration and be rotated through less than a revolution to apply force against the bones. The wedge member may have a porous construction which enables bone to grow through the wedge member and immobilize the joint. The wedge member may be coated with and/or contain bone growth promoting material. The wedge member may be connected to only one of the bones or may be connected to two adjacent bones.

  • Patent number: 6984236
    Abstract: The above-discussed and other problems and deficiencies of the prior art are overcome or alleviated by the improved bone connective prosthesis and method of forming the same of the present invention, comprising the addition of at least one biocompatible metal coupling agent to a prosthetic element, and then adding the biocompatible copolymerizer 2-hydroxyethyl methacrylate (“HEMA”) to the PMMA film and/or cement in an amount effective to enhance the cohesion between the prosthetic and the bone cement. In general, a PMMA/HEMA film is applied to the prosthetic element in the presence of a silane coupling agent by dipping, painting, spraying, etc.

  • Patent number: 6936051
    Abstract: Anatomically contoured anterior cervical plates with bone ingrowth surfaces, providing for intersegmental compressive preloading, and a rigid and locked interface to all of the bone screws, with those engaging the vertebrae deployed in highly convergent pairs. The bone screws have a tapered self-tapping leading end, an increasing root diameter with a generally constant outer diameter with a thread that is narrow and sharp throughout and an enlarged head portion capable of an interference fit to the receiving holes of the plate. Instrumentation consists of plate holders, a compression apparatus and a pilot hole forming device that interlocks with the plate. Methods for spinal compression and bone hole preparation are provided.

  • Patent number: 6875386
    Abstract: A method of producing a biocompatible microporous membrane comprising the steps of providing a biocompatible membrane and using an energy beam to form a set of pores having a minor axis of less than 15 ?m through the biocompatible membrane. One embodiment includes the steps of producing a first layer of material, defining a first set of pores; producing a second layer of material, defining a second set of pores and wherein the second set of pores is defined so as to cooperatively engage the first set of pores; and aligning and joining the first layer of material to the second layer of material to form a laminated membrane, having through-passageways formed by the first set of pores at least partially aligned with the second set of pores.

  • Patent number: 6852128
    Abstract: A spine stabilization system includes a flexible member attachable to a portion of the spinal column. The member includes components that are oriented and function similar to the natural fiber orientation of the anterior longitudinal ligament and annulus tissue. The use of components resist loading applied by extension and rotation of the spine, while the flexibility of the member does not subject it to the compressive loading of the spinal column segment to which it is attached.

  • Patent number: 6846313
    Abstract: A bioabsorbable rivet and pin fastener is formed as an elongated unit that may be used for anchoring, or for attachment of a fixation plate. The rivet has a head mechanically connected to two or more legs that extend generally distally from the head and may flex outwardly from a central rivet axis. The pin is integral with the rivet and oriented along the central axis by a connection such as a web or a plurality of braces, forming an integral, aligned, one-piece assembly that may, for example, be molded as a single piece. The connection breaks under force as the pin is driven into the rivet, so that the pin contacts internal surfaces of the legs and pushes the legs outward into frictional engagement with the surrounding bone. The one-piece assembly may be formed in a gated mold having a central pin with a relief passage that defines the braces between upper and lower portions of the rivet.
