Abstract: A surgical retractor for retracting body tissue in a therapeutic procedure includes two lateral arms each having a block with an aperture extending transverse to a longitudinal axis of the arm. The distal end of each arm pivotably supports a retractor blade. A transverse extension, forming a retractor core, extends through the aperture and slideably supports a lateral arm at each end. A central arm also pivotably supports a retractor blade, and has an extension on a proximal end that is insertable into an aperture within the core. The lateral and central arms are translatable in connection with the core. The retractor blades can be pivoted by rotating a tool engagement. A rack and pinion, controlled by a pawl, is used to translate the side and central arms.

Abstract: A method for retracting body tissue providing a retractor system that includes a rail having two opposed widened rail portions separated by a narrowed portion, each widened portion engageable by a separate clamp. The clamps are configured to support the rail to a fixed surface, or to support a surgical device. Each clamp may independently be positioned or slid along the rail to a desired location without interference with a clamp on an opposing widened rail portion. A device clamp is formed of spherical mating portions which enable alignment of a surgical device along six degrees of freedom, and tightenable by securing a single fastener. A retractor blade mount enables an angular and tilting disposition of a retractor blade, as well as remote manipulation of the retractor blade.

Abstract: Devices, systems, and methods for inserting a vertebral stabilization member, such as a rod. The insertion device includes an outer guide tube, a pin assembly including a pin and a pusher member extending therethrough. The insertion device is configured to actuate a rod between a first orientation and a second orientation angled with respect to the first orientation in order to position the rod in an appropriate location for attachment to bone.

Abstract: An expandable interspinous process fixation system capable of restoring spinal stability and facilitating fusion. In one embodiment, the expandable interspinous process fixation system includes a central ramp, a first endplate, and a second endplate, the central ramp capable of being moved in a first direction to move the first and second endplates outwardly and into an expanded configuration. Each endplate supporting fixed and/or adjustable spinous process engaging plates.

Abstract: A joint spacer therapeutically maintains separation of bones of a joint. A carriage is slideably retained within the frame and has at least one ramped surface. An actuator screw is threadably engaged with the frame, and rotatably connected to the carriage, to cause the carriage to slideably move within the frame when the actuator screw is rotated. First and second endplates engage the bones of the joint, and each has at least one ramped surface that is mateable with the ramped surface of the carriage, whereby when the carriage is slideably moved by rotation of the actuator screw, the endplates ramped surface slides against the carriage ramped surface to cause the endplates to move along an axis transverse to the longitudinal axis of the frame, to increase the height of the spacer. Piercing elements are connected to the carriage to pierce bone of the joint when the carriage is moved.

Abstract: Surgical retractors and methods thereof for retracting body tissue in a therapeutic procedure. The surgical retractor may include retractor blades have openings or channels configured to receive bone pins while maintaining accessibility and visibility of the operative window.

Abstract: Minimally invasive vertebral stabilization systems may include at least one fastener, at least one coupling element connected to the fastener, and an elongate rod member. The fastener is deliverable to a vertebral body of a patient through an opening. The coupling element has at least one extended tab which defines an open central portion and a central longitudinal axis. The elongate rod member is configured to extend through the open central portion and be secured to the coupling element. The extended tab is configured to be removed from the coupling element once the elongate rod is secured to the coupling element.
