  • Patent number: 6322566
    Abstract: Intraoral distractor for callus distraction in the human lower jaw with a proximal (posterior) and a distal (anterior) fixation part and a first displacement mechanism for a linear lengthening of the distance between the two fixation parts so as to lengthen the body of the mandible or the ramus of the mandible in the area of an osteotomy. The distractor is characterized in that the invention provides for a distraction element with a joint, the axis of articulation of which is oriented in such a way as to allow for a change in the angular position to each other of the body of the mandible and ramus of mandible in the area of the osteotomy. The one fixing part is assigned to the ramus of mandible and the other fixing part to the body of mandible. The distraction element is joined to the fixing parts in such a way that it is situated outside the tissue in the oral cavity and on the buccal side of the teeth in the vestibule.

  • Patent number: 6312434
    Abstract: The present invention is directed to a device for producing a shock wave to impact an object that includes a transfer member. The device has a voice coil assembly including a permanent magnet and a bobbin member, wherein the permanent magnet provides a first magnetic field. A hammer is attached with the bobbin member; and a coil is operatively attached to the bobbin member, wherein when a voltage is applied to the coil a second magnetic field is generated that opposes the first magnetic field and thereby propels the hammer to contact the transfer member to cause a shock wave to travel along the transfer member.

  • Patent number: 6309395
    Abstract: A kit of surgical instruments comprises a plurality of differently sized/shaped hollow tubes constructed to receive bone graft, and a plurality of differently sized and/or shaped plungers to be inserted into the hollow tube. A surgeon may select a hollow tube and plunger which correspond based upon the size and shape of the graft receiving area and the prosthesis to be implanted. The plungers are further constructed and arranged so that when the hollow tube is moved in a direction away from a graft receiving area, the bone graft is delivered to the graft receiving area.

  • Patent number: 6293970
    Abstract: The present invention provides a plasticized dehydrated or freeze-dried bone and/or soft tissue product that does not require special conditions of storage, for example refrigeration or freezing, exhibits materials properties that approximate those properties present in normal hydrated tissue, is not brittle, does not necessitate rehydration prior to clinical implantation and is not a potential source for disease transmission. The invention replaces water in the molecular structure of the bone or soft tissue matrix with one or more plasticizers allowing for dehydration of the tissue, yet not resulting in an increase in brittleness of the plasticized product, and resulting in compressive and/or tensile properties similar to those of normal hydrated bone. Replacement of the chemical plasticizers by water prior to implantation is not required and thus, the dehydrated bone or soft tissue plasticized product can be placed directly into an implant site without significant preparation in the operating room.

  • Patent number: 6293909
    Abstract: An endoscopic assembly, utilizing a braided mesh material as an expandable sheath, is disclosed. The mesh sheath is adapted to receive an endoscope for viewing the interior of a body cavity or lumen and one or more channels for performing medical procedures within the patient. The mesh sheath expands laterally as it is compressed longitudinally, which allows it to come into contact with the interior of the body cavity. By doing so, it can anchor the assembly, take samples from the body cavity, or dilate a stricture in the body cavity. Additional dilation procedures can be performed by removing the endoscope and inserting other instruments without removing the entire assembly from the patient. The body cavity can be hermetically sealed to reduce the risk of contamination of the endoscope and channels.

  • Patent number: 6290701
    Abstract: Bone fasteners consisting of a rivet and an expansion pin for attaching soft tissue and bone plates to bone. The rivet has an enlarged proximal end, a tubular body portion dimensioned to fit snugly within a hole drilled in a bone, and a distal end having expandable legs. The expansion pin is either slidably or rotatably mounted within an axial bore in the rivet. In a first embodiment, the expansion pin has a metallic traction portion and a conical, preferably bioabsorbable, distal end portion releasably affixed thereto. In use, the rivet is inserted into a pre-drilled hole in a bone. When tension is applied to the traction portion of the expansion pin, the conical end portion progressively advances into the bore thereby forcing the legs on the distal end of the rivet to expand outwardly. When the legs are fully expanded, further progress of the conical portion is arrested by a shoulder stop within the axial bore.
