Patent number: 8828018Abstract: A bone cage placement device used to insert and position a bone cage in the disc space. Once the bone cage is positioned, a selector tool is inserted into the center aperture of the bone cage placement device. The end of the selector tool has a cam lift driving feature which is used to rotate the cam lift of the bone cage and expand the bone cage to the desired height. The selector tool is removed, and a graft placement tool and plunger are used to insert bone graft material into the plug. An end plug installation tool and installer are then used to insert an end plug to prevent leakage of material from the bone cage. The bone cage is released from the bone cage placement device, which is then removed from the patient's body.Type: GrantFiled: December 13, 2010Date of Patent: September 9, 2014Inventors: Ashraf A. Ragab, James A. Rinner

Patent number: 8821508Abstract: A bone fixation plate for fixation of fractures having a small terminal bone fragment, such as fractures of the distal radius. The plate includes an elongated body, and two hook members extending from a first end of the elongated body. A contoured region is configured to approximate the surface contour of the distal radius proximate the volar rim, the dorsal rim, or the radial arm. Each hook member is configured to provide subchondral support to a distal bone fragment, without causing shortening of the fragment into the metaphyseal bone, and without providing a bending torque directed to the base of the plate. The tooth members of the hook plate are preferably sharpened at their tips and edges to facilitate their impaction. A holder/impactor for gripping the radial hook plate, and for further facilitating impacting of the hook plate without the need to pre-drill pilot holes, is also provided.Type: GrantFiled: August 29, 2012Date of Patent: September 2, 2014Assignee: Trimed, IncorporatedInventors: Robert J. Medoff, Alexander Y. Shin

Patent number: 8821507Abstract: The tissue augment sheet delivery system includes a tube funnel adapter and a tissue augment sheet delivery instrument. The tube funnel adapter includes a oval/conical shaped funnel. The tissue augment sheet delivery instrument includes a handle. A cylindrical tube is connected to the handle. A wire is inserted in the tube. The wire is formed in a large loop with small loops formed in the large loop. A tissue augment sheet is attached to one side of the large loop using a monofilament. In use, the tube funnel adapter is inserted in body. The tissue augment sheet is placed in mouth of the oval/conical shaped funnel and gently moved down. While moving down, the tissue augment sheet conforms to the internal diameter of the tube funnel adapter. The handle is withdrawn to remove the large loop from the body leaving the tissue augment sheet in body.Type: GrantFiled: July 6, 2007Date of Patent: September 2, 2014Assignee: Howmedica Osteonics Corp.Inventors: Stuart L. Axelson, Jr., Damon Servidio, Jon B. Tucker, Jeffrey Kapec, Yoshi Matsuda, Yukiko Naoi, Kazuna Tanaka, Richard M. Seldes

Patent number: 8814879Abstract: Systems and methods for repairing annulus defects include at least one blocking member positionable in or adjacent to the annulus defect, at least one attachment portion for securing the blocking member to adjacent tissue, and instruments for placing and engaging the blocking member in and/or adjacent to the annulus defect. The blocking member extends at least partially across the annulus defect for repair of the defect and/or retention of nucleus material, one or more implants, bio-compatible materials or device, and/or other objects positioned in the disc space.Type: GrantFiled: November 21, 2011Date of Patent: August 26, 2014Assignee: Warsaw Orthopedic, Inc.Inventors: Hai H. Trieu, Lehmann K. Li

Publication number: 20140236162Abstract: An apparatus for displacing an implant, such as a pacemaker or ICD generator or loop recorder, which can be used during surgical procedures to facilitates manipulation of the implanted device. The apparatus can be used to apply force to the implant in order for the operator to tug to loosen the implanted device without causing unnecessary movement or dislodgement of implanted leads that are connected to the implanted device. The apparatus can have features of various shapes and sizes depending on the size of the patient as well as size and shape of the implanted device.Type: ApplicationFiled: February 19, 2013Publication date: August 21, 2014Inventor: Mark Barongan

Patent number: 8808307Abstract: A tool for holding or driving an implant member having a recess is provided including an elongate tool shaft having a distal head portion for being received in the recess and a securing mechanism that keeps the head portion in the drive recess and which is disposed proximally up along the tool shaft from the distal head portion. In one form, the securing mechanism includes a plurality of resilient leg member having distal end locking portions. In another form, a drive system includes a drive tool and a driven member. The drive tool has a generally annular flange portion that is radially larger than the drive head portion. The driven member has a generally annular securing portion for receiving the flange portion in releasably locked engagement so that the circumferential extent of the locking engagement is maximized relative to the smaller radial size of the drive head portion.Type: GrantFiled: October 13, 2011Date of Patent: August 19, 2014Assignee: Pioneer Surgical Technology, Inc.Inventor: Daniel Rae Robinson

Patent number: 8808305Abstract: The present disclosure relates to a spinal fusion impactor tool that includes an attachment means for securing an implant device to the distal end of the tool, a means for adjusting the angle of the distal head relative to the handle to better position the implant for introduction into the implant site, means for remotely releasing the implant device at the distal end and a clamp device on the shaft of the tool to secure tabs, attachments and other devices. The impactor tool is preferably used in conjunction with implantation of an intervertebral fusion cage that is equipped with shims having tabs or other removing means, but may also be used to introduce, for example, an implant, graft, fusion device, wedge or distractor device into any joint space or bony region in preparation for implantation.Type: GrantFiled: October 1, 2012Date of Patent: August 19, 2014Inventor: Jeffrey B.
