An implant assembly is provided for surgical implantation into an intervertebral space S, such as for stabilization of vertebrae V adjacent the intervertebral space S during a spinal fusion procedure. The implant assembly includes a primary segment separate from a secondary segment. These segments are elongate and of sufficiently small cross-section that they can be implanted posteriorly in a minimally invasive manner. The segments preferably have a rectangular cross-section so that they can be inserted on a side into the intervertebral space S and then rotated into a maximum height orientation to widen the intervertebral space S. The segments interlock together at an intersection there between. The primary segment preferably includes a tunnel and the secondary segment preferably includes a neck with the tunnel and neck sized complementally so that the segments stabilize each other where they intersect with the neck within the tunnel. The entire implant assembly is thus provided which both widens and supports the intervertebral space S and is sufficiently rigid to provide adequate support for the intervertebral space S as the vertebrae V are fusing together.

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.

Various implants are provided to at least partially replace a nucleus of a spinal disk. The implants are spring-like in nature. In one embodiment, a helical spring is provided with various different unique outlines to act as the implant. The helical spring is oriented with a center line substantially perpendicular to the spine and to a direction of compression loads experienced within the disk space. The helical spring or other implant is preferably delivered through a delivery cannula which has a size which is smaller than a cross-sectional size of the implant. The implant is preferably formed of nickel titanium or otherwise configured so that it can be compressed significantly within the delivery cannula and then become enlarged after being advanced out of the delivery cannula and into the intervertebral space. In other embodiments the implant is generally cylindrical and expandable in height after delivery.

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.

The invention relates to a spinal implant to be inserted between two vertebra to support and stabilize adjacent vertebra and allow for physiological motion. One embodiment of the implant includes an upper assembly and a lower assembly, where the assemblies are adapted to articulate relative to one another. This implant also includes elongate elements that are deployable between a closed position and an open position. Portions of the implant can interlock to form various shapes. The invention includes an implantable device to support the vertebrae, and a minimally invasive method for inserting and deploying the device within the intervertebral space.

An expandable surgical access device can include an elongate member comprising an expansion lumen between a proximal end and a distal end, and an expandable body operably attached to the distal end of the elongate member. The expandable body can be inserted to an internal location in a body in a collapsed configuration. When in a desired position, the expandable body can be expanded outward to an expanded configuration. In the expanded configuration, the expandable body can be adapted to protect adjacent anatomical structures and can have an internal diameter defining an operating lumen sufficient to allow passage of a cannula through the operating lumen. The expandable body may be further expanded inward to a constricting configuration whereby the expandable body can be adapted to constrict about and anchor the cannula in the operating lumen.
