Patent number: 7674297Abstract: A spinal fusion system includes a cage with a fillable volume and removable locking gate, thereby enabling the fillable volume to be packed with graft, biologic or other materials prior to the gate being closed and locked. In the preferred embodiment, the locking gate is positioned anteriorally, though lateral, posterior, and combinations thereof are also possible. The cage is preferably radiolucent, being composed of a carbon fiber, but with one or more radiopaque markers to provide a certain degree of visualization. Some or all of the walls of the cage may include superior and/or inferior surface features to enhance positioning and/or minimize back-out, and the posterior wall may be indented to prevent neurocompression. The sidewalls of the cage may further include a recessed face with nipple indents and locking fasteners. According to a system aspect of the invention, multiple cages are provided, each being shaped differently for use at different spinal levels.Type: GrantFiled: June 16, 2003Date of Patent: March 9, 2010Assignee: U.S. Spinal Technologies, LLCInventor: Mark H.

Publication number: 20050234459Abstract: A system for performing bone arthrodesis includes an implant for bone arthrodesis and a bone fastening device. The implant includes a fastener with an elongated shaft having a head at one end and a bone-piercing point at the opposite end. A first washer has structure for engaging the head of the shaft so as to be polyaxially pivotable with respect to the head. A locking member has structure for engaging the shaft. The locking member can have a second washer pivotally engaged thereto. The bone fastening device can include an elongated cannula with a collet for detachably engaging the first washer and for advancing the first washer. Structure is provided for engaging the fastener and for advancing and rotating the fastener through the collet and through the first washer. The bone arthrodesis device further includes a lower end portion extending from the cannula. The lower end portion has structure for detachably engaging the locking member.Type: ApplicationFiled: October 26, 2004Publication date: October 20, 2005Applicant: U.S. SPINAL TECHNOLOGIES, LLCInventors: Mark Falahee, Leonel Dominguez, John Pepper, Ian McDermott, K.
