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.

Dynamically expandable cannulae and systems and methods for performing percutaneous surgical procedures employing same

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.

Expandable surgical access device and methods of use

An implant assembly is provided for surgical implantation into an intervertebral space, such as for stabilization of vertebrae adjacent the intervertebral space 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 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 and is sufficiently rigid to provide adequate support for the intervertebral space as the vertebrae are fusing together.

Intervertebral space implant for use in spinal fusion procedures

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.

Minimally invasive spinal disc stabilizer and insertion tool

A system of instruments and a method for using these instruments for effective spinal stabilization using cannulated bone screws is described. In particular, the system and method provides accurate and efficient measurement of the appropriate screw length to be inserted in a patient with a lower spine injury. The system and method further enables accurate orientation or placement of the cannulated bone screws from outside the patient's body. The present method describes a surgical technique for the placement of cannulated bone screw for translaminar facet, transfacet, and general orthopedic applications.

Surgical guide system for stabilization of the spine

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. The segments are fitted with height expansion systems which can be accessed after implantation of the segments so that height of the segments can be further increased, particularly at distal ends of the segments , such that the intervertebral space S can be provided with a desirable amount of lordosis.
