Publication number: 20120277864Abstract: A cannula assembly and related methods of use. The cannula assembly includes a cannula and a stylet. The cannula has an outer surface that is non-circular. Rotation of the cannula about its longitudinal axis changes the orientation of the cannula's larger outer dimension so that the cannula may be used as a distraction tool. Rotation is effected by rotating a stylet handle, which rotates the associated stylet shaft, which in turn rotates the cannula. Related methods include rotating a handle of the stylet, while the shaft of the stylet is disposed in the bore of the cannula, about the first longitudinal axis so as to rotate the cannula about the longitudinal axis to distract vertebral bodies.Type: ApplicationFiled: April 26, 2011Publication date: November 1, 2012Applicant: WARSAW ORTHOPEDIC, INC.Inventors: Darrel S. Brodke, Carl Lauryssen, Frank M. Phillips, Gary A. Schneiderman, Bruce Chabansky, Calin Druma

Publication number: 20120130161Abstract: In one form, a system for use in percutaneous surgical procedures includes a cannula having an elongate body extending along a longitudinal axis between a proximal end and a distal end and including a working channel dynamically expandable from a first, unexpanded configuration. The system also includes a device that is positionable in and engageable with the working channel to expand the working channel from the first configuration as the device is moved through the working channel. In response to disengagement of the device with the working channel, the working channel returns to the first, unexpanded configuration. In one aspect of this form, the device includes an interbody spinal implant that is deliverable to a surgical site through the working channel of the cannula. In another form, a method for performing a percutaneous surgical procedure is provided. However, different forms and applications are envisioned.Type: ApplicationFiled: November 24, 2010Publication date: May 24, 2012Applicant: KYPHON SARLInventors: Carl Lauryssen, Gary A.

Publication number: 20110060368Abstract: A method of providing spinal stabilization is provided herein. More specifically, the method includes positioning a plurality of fixation assemblies within a plurality of vertebrae in a trans-lamina orientation wherein each fixation assembly includes a proximal portion configured to securely receive a stabilization element (e.g., a stabilization rod). The proximal portions of the various fixation assemblies can be aligned so as to secure at least one stabilization element in a desired position (e.g., along and above a midline of the patient's spine, adjacent and parallel to the midline). A system for providing spinal stabilization is also provided which utilizes trans-lamina delivery and positioning of fixation assemblies within target vertebrae thereby providing stronger fixation and a significant reduction in associated tissue damage.Type: ApplicationFiled: November 16, 2010Publication date: March 10, 2011Applicant: DEPUY SPINE, INC.Inventors: Bradford L.

Publication number: 20090012619Abstract: A motion restoring intervertebral prosthesis for replacing a failed or partially failed natural disc comprises two components defining an imaginary longitudinal axis generally aligned with the spinal axis when installed, the components having vertebral body engaging surfaces on one side and mating articulating surfaces on the other side, with peripheral rims encircling the articulating surfaces. The articulating surfaces accommodate rotational motion about the longitudinal axis and limited pivotal motion about the A/P and M/L planes. The rims are arranged to contact and limit the pivotal motion between the components to about +/?6° and preferably +/?4° in both directions in the M/L plane and in the A/P plane in the forward direction. Optionally, the encircling rims allow pivotal action of about 20° to 30° in the A/P plane in the rearward direction.Type: ApplicationFiled: July 3, 2007Publication date: January 8, 2009Inventors: Nicholas M.

Publication number: 20050182404Abstract: An anterior bone plate system is provided that promotes osseous fusion and allows subsidence while restricting extension. The bone plate system requires a minimum number of screws for securing the plate onto bone, thus reducing the amount of osseous tissue damage incurred by the bone structures to which they are attached. The system is also simple to use and provides for independent screw placement while incurring minimal soft tissue damage from lateral retraction. A method for implementing the system is also provided.Type: ApplicationFiled: April 25, 2005Publication date: August 18, 2005Applicant: DEPUY SPINE, INC.Inventors: Carl Lauryssen, Morris Cesarone, Dennis Cirino, Danielle Sheeran
