Patent number: 7608096Abstract: An apparatus is provided for correcting spinal abnormalities, and particularly for providing compression and/or distraction of vertebrae without additional tools or instrumentation. A plate member is provided with a plurality of slots, one of which has a sloped internal edge or surface. The plate is anchored to one vertebra by a first anchor, and a second anchor is then placed through the slot with the sloped internal edge or surface and tightened. Such tightening causes the plate to move with respect to the tightened anchor, and thus to transmit compression or distraction to the vertebrae. The apparatus is particularly useful in minimally-invasive surgeries but can also be used in more traditional open surgeries.Type: GrantFiled: March 10, 2003Date of Patent: October 27, 2009Assignee: Warsaw Orthopedic, Inc.Inventors: Kevin T. Foley, Aure Bruneau, Anthony J. Melkent, Thomas E. Roehm, III

Patent number: 6152871Abstract: Devices and methods for performing percutaneous surgery under direct visualization through a single cannula are shown. A device includes an elongated cannula sized for percutaneous introduction that defines a working channel between its ends. The working channel is sized to receive one or more surgical tools therethrough. A clamp assembly is engaged to the outer surface of the cannula. The clamp assembly includes a viewing element receiving portion and a viewing element includes a clamp assembly engaging portion for removably engaging the viewing element to the clamp assembly. In one embodiment, the receiving portion defines a receptacle for receiving a dovetail included on the engaging portion of the viewing element. The receiving portion may also include a pivotable clip for removably engaging a protuberance of the engaging portion. The clamp includes a mechanism that allows translation, rotation, and removal of the clamp assembly and the viewing element with respect to the cannula.Type: GrantFiled: September 25, 1998Date of Patent: November 28, 2000Assignee: SDGI Holdings, Inc.Inventors: Kevin T.
