  • Patent number: 7396232
    Abstract: Devices and methods for gradual displacing of the soft tissues covering bones. The gap developing between the bone and the displaced soft tissue will be filled with bone callus as it is in distraction osteogenesis. The devices and methods allow formation of bone in distraction osteogenesis without cutting a segment of the bone. The devices and methods are particularly useful in dental implantology for vertical ridge augmentation by displacing the periosteal tissue and for sinus lift by displacing the Schneiderian membrane. The devices and methods can also regenerate soft tissue between the bone and the displaced soft tissue.

  • Patent number: 7390298
    Abstract: An expandable surgical retractor for use in minimal incision surgery is disclosed. The retractor consists of a fiber optic central rod surrounded by flexible wires designed to create an open space for visualization and surgical work within an illuminated surgical field. The flexible wires are disposed via selective pressure of the surgeon and are variable in number. The configuration will allow for both forward and back illumination of the surgical field. The expandable surgical retractor allows for surgical visualization in anatomical areas heretofore too complicated for surgical consideration. Other embodiments of the expandable surgical retractor are contemplated wherein a handle with an aperture may replace the central rod. The flexible wires may fit in openings around the aperture. The handle, in this embodiment, may have a light source and may be adapted to be used in select areas of anatomy. Further, the handle may be transparent.

  • Patent number: 7381054
    Abstract: A denture remover includes an elongated, hollow shaft having a lower end and an upper end with an angled portion at the upper end. A suction cup is attached to a distal end of the angled portion. A vacuum release tube extends from the suction cup to an air port within the shaft interior having a spring-biased valve normally positioned therein. A handle is slidably mounted on the shaft and is fastened to the valve. A denture is removed by fastening the suction cup thereto in a conventional fashion. A user simply grasps the handle and pulls the attached denture from the wearer's mouth. To release the denture, a user slides the handle to remove the valve from the port allowing air flow to the suction cup aperture thereby eliminating the vacuum created by the suction cup.

  • Patent number: 7377898
    Abstract: A surgical wound retractor is adapted to dilate a wound stretchable to a desired diameter, the retractor includes a first ring having a diameter greater than that desired for the wound and being adapted for disposition interiorly of the wound. A second ring has a diameter greater than that desired for the wound and is adapted for disposition exteriorly of the wound. A plurality of retraction elements are disposed in a generally cylindrical relationship to each other, between the first ring and the second ring. These elements extend through the wound to exert a radial retraction force on the wound which is dependent on the distance separating the first ring and the second ring Retraction elements, both distensible and non-distensible are contemplated with appropriate attachment means at the rings to provide for variations in the retraction force. With a suitable retraction sleeve, a third ring can be provided to form a circumferential retainer to vary the retraction force.

  • Patent number: 7357635
    Abstract: A method and apparatus are provided for changing the form of the jaw and facial bones of an adult patient that did not develop fully during childhood. The method utilizes a device having a plate body with an expansion screw that fits within the mouth of the patient; flap springs that project from the plate body, and an overlay extending from the plate body. The device is placed within the mouth of the patient so that the overlay is in a position between at least two opposing teeth. In this position, opposing teeth contact the overlay during function (e.g. swallowing). This intermittent, unilateral application of force to the facial bones causes these bones to further develop, positioning out of place teeth into more proper positions, and inducing a more symmetrical and enhanced appearance of the face, as well as increasing the airway space behind the jaws. Concomitantly, the flap springs gently press against selected teeth that are out of alignment in order to guide those teeth into place.
