Publication number: 20070055246Abstract: A supplemental spine fixation device and method is used in association with a primary spine fixation device. The supplemental spine fixation device includes a guide and spacer for distracting apart adjacent spinous processes and the device has hook members which hook about the first and second spinous processes. With the spinous processes distracted and the hook members about the spinous processes, the hook members can be rigidly secured to a hub in order to rigidly affix the spinous processes about the spacer. The rigidity between the spinous processes assures that the vertebral bodies will be held rigidly in place in order to promote bone growth and fusion. Further additional freedom of movement between the spacer and hub is accomplished with the spacer being pivotably mounted relative to the hub. The hooks have a tissue distracting lead-in guide for allowing the hooks to be easily urged between spinous processes.Type: ApplicationFiled: November 3, 2006Publication date: March 8, 2007Applicant: St. Francis Medical Technologies, Inc.Inventors: James Zucherman, Ken Hsu, T. Fallin, Henry Klyce

Publication number: 20070010813Abstract: Systems and method in accordance with an embodiment of the present invention can includes an implant comprising a first wing, a spacer extending from the first wing, and a distraction guide. The distraction guide is arranged in a first configuration to pierce and/or distract tissue associated with adjacent spinous processes extending from vertebrae of a targeted motion segment. The implant can be positioned between the adjacent spinous processes and once positioned, the implant can be arranged in a second configuration. When arranged in a second configuration, the distraction guide can act as a second wing. The first wing and the second wing can limit or block movement of the implant along a longitudinal axis of the implant.Type: ApplicationFiled: March 17, 2006Publication date: January 11, 2007Applicant: St. Francis Medical Technologies, Inc.Inventors: James Zucherman, Ken Hsu, Charles Winslow, John Flynn, Steven Mitchell, Scott Yerby, John Markwart

Publication number: 20060271049Abstract: An embodiment of a system in accordance with the present invention can include an implant having a spacer with a thickness and a wing, wherein a first configuration of the wing has a first height substantially similar to the thickness and wherein the wing is adapted to be selectably arranged in a second configuration such that the wing has a second height greater than the first height. A periphery of the implant has a shape generally conformal with a shape of an inner surface of a cannula and a cross-sectional diameter smaller than an inner diameter of the cannula. The cannula is inserted such that a proximal end of the cannula is arranged between the adjacent spinous processes. The implant is then urged into position between the adjacent spinous processes by way of the cannula, and subsequently arranged in a second configuration to fix the implant in position.Type: ApplicationFiled: March 24, 2006Publication date: November 30, 2006Applicant: St. Francis Medical Technologies, Inc.Inventors: James Zucherman, Ken Hsu, Henry Klyce, Charles Winslow, Scott Yerby, John Flynn, Steven Mitchell, John Markwart

Publication number: 20060265066Abstract: Systems and method in accordance with an embodiment of the present invention can includes an implant comprising a spacer and a frame having a central body and a helical shaped wing extending from the central body. The frame can be positioned near about adjacent spinous processes, and can be rotated and urged so that the adjacent spinous processes pass within a groove of the wing, thereby allowing the wing to be arranged on an opposite side of the adjacent spinous processes. The spacer can then be arranged over the frame so that the spacer contacts and distracts the spinous processes, thereby limiting relative movement of the adjacent spinous processes during extension.Type: ApplicationFiled: March 17, 2006Publication date: November 23, 2006Applicant: St. Francis Medical Technologies, Inc.Inventors: James Zucherman, Ken Hsu, Charles Winslow, John Flynn, Steve Mitchell, Scott Yerby, John Markwart
