Patent number: 7547318Abstract: A spinal fixation element is provided having a feature formed thereon that facilitates placement of the spinal fixation element through an access device, thus allowing the spinal fixation element to be positioned in relation to a spinal anchor that is coupled to the access device and that is implanted in a vertebra in a patient's spine. The feature also optionally facilitates placement of the spinal fixation element in relation to spinal anchors implanted in adjacent vertebrae. In particular, the spinal fixation element is adapted for use with an access device that has at least one slot or opening formed therein and having a width that is less than a width of the feature, thus preventing the feature from passing therethrough. The spinal fixation element can therefore be inserted through the access device, and a portion of the fixation element can be passed through the slot or opening in the access device while the feature is retained in the access device.Type: GrantFiled: March 19, 2004Date of Patent: June 16, 2009Assignee: DePuy Spine, Inc.Inventors: Paul Birkmeyer, Michael Zajack, Erasmo Lopez, Ramon Ruberte

Patent number: 7476240Abstract: A method for introducing a spinal fixation element between two bone anchors includes engaging a spinal fixation element to a shaft of an instrument, positioning the shaft of the instrument through a sidewall opening of a first percutaneous access device connected to a first bone anchor and through a side wall opening of a second percutaneous access device connected to a second bone anchor, the spinal fixation element extending in an orientation substantially parallel to the longitudinal axis of at least one of the first percutaneous access device and the second percutaneous access device, and pivoting the instrument to change the orientation of the spinal fixation element and position the spinal fixation element in proximity to the first bone anchor and in proximity to the second bone anchor.Type: GrantFiled: February 3, 2005Date of Patent: January 13, 2009Assignee: Depuy Spine, Inc.Inventors: Douglas Raymond, James Roveda, Brian Murphy, Christopher Sicvol, Sean Selover, Erasmo Lopez, Ramon Ruberte, Bryan S.

Publication number: 20080177294Abstract: The invention includes a system and method for loosening of tissue. In one embodiment, an intervertebral tissue removal system includes at least one abrading member for abrading tissue in an area to be cleared and at least one expandable member operable to be expanded from a first condition to a second condition, wherein the volume defined by the at least one expandable member in the second condition is greater than the volume defined by the at least one expandable member in the first condition, the at least one expandable member operably connected to the at least one abrading member such that as the at least one expandable member expands from the first condition to the second condition, the at least one abrading member is moved from a first position to a second position.Type: ApplicationFiled: October 16, 2006Publication date: July 24, 2008Applicant: DePuy Spine, Inc.Inventors: Michael J. O'Neil, Ramon A. Ruberte, Shawn D. Stad, John Riley Hawkins

Publication number: 20080058933Abstract: The present invention provides a device and methodology for use in spinal fusion surgeries. An implant is proved for forming a rigid structure between adjoining vertebrae in a patient. The implant is a cage defined by at least a first end, second end, first side, and second side surface, wherein first and second side surfaces extend substantially parallel to each other to span a space between adjoining vertebrae and first and second ends interconnect said first side surface and second side surface. The cage incorporates one or more flexible joints that allow the cage to be deformed for insertion into a patient. The ability to deform the cage allows a greater ease and flexibility in inserting and positioning the implant.Type: ApplicationFiled: July 31, 2006Publication date: March 6, 2008Inventors: Ronald Garner, Sara Dziedzic, Michael Mahoney, Ramon Ruberte

Publication number: 20070167954Abstract: A percutaneous access device includes an inner tube and an outer tube disposed about at least a portion of the inner tube. The outer tube may be sized to span from a skin incision in a patient to a site proximate the spine of the patient. The distal end of the outer tube may be adapted to releasably engage a bone anchor. The inner tube may be adjustable relative to the outer tube between a first position and a second position in which the distal end of the inner tube contacts the bone anchor. A bone anchor assembly includes a bone anchor having a distal bone engaging portion and a receiving member having a recess for receiving a spinal fixation element. The proximal end of the receiving member may have an arcuate groove formed on an exterior surface thereof to facilitate connection of an instrument to the receiving member.Type: ApplicationFiled: March 28, 2007Publication date: July 19, 2007Inventors: Christopher Sicvol, Erasmo Lopez, Ramon Ruberte

Publication number: 20070150064Abstract: Devices and methods for treating diseased or damaged portions of an intervertebral region are provided. In particular, intervertebral implants that can include use of a tissue regeneration structure having small intestine submucosa are described. The intervertebral implants can be utilized with any combination of load bearing structures for supporting loading on the implant, shaping structures for biasing the configuration of the implant, collapsible support structures for shaping the implant, and other features. Implants can also be formed with an enclosure to contain a filling material, such as an injectable small intestine submucosa formulation. Methods of delivering and utilizing the various implants are also discussed.Type: ApplicationFiled: December 22, 2005Publication date: June 28, 2007Applicant: DePuy Spine, Inc.Inventors: Ramon Ruberte, Michael O'Neil, Patrick DeDeyne
