  • Patent number: 9649410
    Abstract: A metal implant for use in a surgical procedure is provided with a surface layer that is integral with the metal substrate, and which incorporates a biocidal material. The surface layer may be grown from the metal substrate, by anodising, and the biocidal material incorporated in it by ion exchange. Alternatively the layer may be deposited by electroplating, followed by diffusion bonding so as to become integral with the metal substrate. In either case, silver is a suitable biocidal material; and both the release rate and the quantity of biocidal material should be low to avoid toxic effects on body cells. Electropolishing the surface before formation of the surface layer is also beneficial, and this may be achieved by electropolishing.

  • Patent number: 8506608
    Abstract: An orthopedic screw is used in a fixation device for treating fractures. The device has a body with holes to accept the bone screws. The bone screws have a layer of bioresorbable material on the shaft. Engagement between the bone screws and the body is initially through the bioresorbable material, which engagement rigidly fixes the relative angular orientation between the bone screws and the body when the device is applied to a bone. As the bioresrobable material is resorbed the angular relation between the bone screws and the body is no longer rigidly fixed, thereby effecting a transformation from rigid osteosynthesis to flexible osteosynthesis to allow micromotion between the bone fragments which promotes healing.

  • Patent number: 8439952
    Abstract: The invention provides a connecting rod for bone anchors such as pedicle screws. The rod is constructed to include a main shaft portion that is not bioresorbable and a tip portion that is bioresorbable. The tip facilitates percutaneous insertion into a patient's body. After placement of the rod, the bioresorbable tip is resorbed preventing post-operative complications such as impingement of adjacent spinal facet joints.

  • Patent number: 8439919
    Abstract: An implant (4) is provided with attachment and hole-insert parts (2, 3) with surfaces which have different degrees of finishing and/or degrees of roughness and/or porosities (2f, 2g). Arranged on the surfaces there is at least one dozen (A-B) in which the degree of finishing and/or the degree of roughness and/or the porosity is continuously changed. The changes in porosity in said zones can mirror continuous or discontinuous changes in the bone in question, for example the jaw bone or tooth bone. The continuously changed zones can be obtained with the aid of electrolyte (15) and, connected to the latter, an anode and cathode arrangement (13, 14). When establishing the porosity, it is possible to mask different portions of the respective implant and to control the temperature of the implant.

  • Patent number: 8398638
    Abstract: A method of treating a spinal disk according to the present invention can include inserting an alloplastic bulking agent into the spinal disk to treat the defect. The alloplastic bulking agent has a plurality of microparticles. The bulking agent results in at least one of sealing the defect, increasing a pressure of the disk, increasing a height of the disk, improving stability of the disk and improving structural integrity of the disk.

  • Patent number: 8372126
    Abstract: Surgical fasteners that combine mechanical and osteogenic means of fixation to maximize in vivo stability and long-term performance. The fastener generally includes a head and a shaft. The fastener is fenestrated and includes a channel that leads into one or more openings along the shaft. Bone void filling materials is delivered through the channel to the shaft to improve anchoring. In one embodiment, the osteogenic means comprise a coating applied to the fastener to improve bony apposition. The fastener with combined mechanical and osteogenic means provides initial, immediate anchoring and long term anchoring.

  • Patent number: 8337529
    Abstract: Spinal stabilization mechanisms act to prevent lateral bending, extension, and rotation across adjacent vertebrae. Methods for spinal stabilization includes placing one or more anchors at each vertebral level, positioning one or more sutures around each anchor at each level such that the each suture forms a loop or band around two adjacent anchors, applying tension to the ends of each suture to tighten the suture loop around the anchors and welding overlapping ends of each suture together to form suture bands connecting the anchors and thereby preventing lateral bending, extension, and rotation of the spinal segment. An in-growth component is placed over the anterior portions of the three adjacent vertebrae and the disk space therebetween. An anti-adhesion patch is placed over the in-growth component, anchors and elongate members. The anti-adhesion patch has one or more notches that provide access to at least two of the anchors and a flap extending from between the notches.

  • Patent number: 8287909
    Abstract: Continuous processing methods for making absorbable polymeric non-wovens with one or more of the following properties: high burst strength, fine fibers of average diameter from 1 ?m to 50 ?m, and thickness from 10 ?m to 50 mm, have been developed. Improved fiber cohesion is made possible by allowing the fibers of the non-woven to initially remain molten during web collection. In the preferred embodiment, the polymer is a polyhydroxyalkanoate, and in the most preferred embodiment, the polymer comprises 4-hydroxybutyrate. A particularly preferred embodiment is a non-woven of poly-4-hydroxybutyrate or copolymer thereof, wherein the non-woven has a burst strength greater than 0.1 Kgf, wherein the non-woven is derived by a continuous melt-blown process. The non-wovens can be used for a variety of purposes including fabrication of medical devices.

  • Patent number: 8246620
    Abstract: An abrading device including 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.
