The preferred embodiment of the present invention is generally described as a lordotic pre-sacral rod implant, or implant construct, for use in association with spinal fusion procedures. In an embodiment, the lordotic pre-sacral rod implant incorporates a washer configured to press against the endplate of the L5 vertebral body and thereby force the vertebral bodies of the lumbosacral junction into a lordotic orientation.

Certain embodiments of the invention relate to a surgical procedure resulting in the fusion of transverse processes. The disclosure herein presents novel approaches for accessing transverse processes of the spine, novel methods for the delivery of fusion material for the fusion of said transverse processes, and novel tools to facilitate the procedure. Certain embodiments of the invention include a graft delivery assembly, which has a delivery shaft, delivery sheath, and at least one curved rod. Bony material is position with a graft delivery assembly, in which retraction of the delivery shaft or sheath places the bone fusion material to the fusion site. The graft delivery assembly further includes features to decorticate and prepare the bone surface for fusion.

Method and apparatus for minimally invasive posterolateral spinal fusion

Minimally invasive surgical techniques including techniques and implants for provision of therapy to a spine from a lateral approach. Implants that may be used with other approaches to the spine are disclosed. Minimally invasive surgical techniques using one or more extended retractors to create an extended access route such as the non-limiting example of lateral access to the spine. Minimally invasive surgical techniques using internal retractors that may be reversibly expanded with a removable retractor inserter to create an extended access route. A linkage jack to expand a set of two or more extended retractors to create an extended access route.

Disclosed are surgical tools, tool sets and methods for percutaneously accessing and preparing treatment sites within the spine for subsequent treatment procedures. The treatment site may be an inter-vertebral motion segments in the lumbar and sacral regions of the spine. The tool set may comprise introducer tools and bone dilators for accessing and tapping into a targeted site, such as, for example, the anterior surface of the Svertebral body. The tool set may also comprise cutters and extractors for preparing the treatment site for subsequent treatment procedures. The tool set may additionally comprise a bone graft inserter, an exchange system, and/or a temporary distraction tool for further preparing the treatment site for subsequent treatment procedures.

Method and apparatus for removable spinal implant extending between at least two adjacent vertebral bodies

Multi-membrane prosthetic nucleus and implants using same are disclosed having an outermost membrane that is semi-compliant and limits the innermost membrane and any intermediate membranes that are highly compliant from bulging out of any opening in the annulus fibrosus. The outermost membrane may help protect the innermost membrane from trauma including any trauma before the innermost membrane is expanded through the injection of prosthetic nucleus material and trauma during the expansion of the innermost membrane in response to the injection of prosthetic nucleus material. Also disclosed is a coated membrane which combines the mechanical properties of the foundation layer with the low permeability to the passage of the flowable prosthetic material of the coating. This coated membrane is semi-compliant and prevents the prosthetic nucleus from bulging out of any openings in the annulus fibrosus. Use is made of injected prosthetic nucleus material that changes to a non-flowable state.

A driver for delivering an insert to a bone anchor, the bone anchor having an internal cavity with a set of internal threads, the driver adapted to rotate with respect to a bone anchor that is anchored in a vertebral body in order to engage external threads on the insert with the set of internal threads in the bone anchor and axially advance the threadedly engaged insert within the bone anchor while simultaneously preventing the bone anchor from rotating with respect to the vertebral body the driver having: 1) a threaded retention rod for engaging a bore in the insert; 2) a driver head to engage with the insert to apply torque to the insert and rotate the insert; and 3) an anchor stabilizer to engage with a proximal face of the bone anchor to prevent the bone anchor from rotating with respect to the vertebral body.

Spinal motion preservation assemblies adapted for use in a spinal motion segment are disclosed including the process for delivering and assembling the spinal motion preservation assemblies in the spinal motion segment via an axial channel created with a trans-sacral approach. Many of the spinal motion preservation assemblies make use of a dual pivot. A number of different embodiments of spinal motion preservation assemblies are disclosed which include at least one component adapted for elastic deformation under compressive loads. The disclosed mobility preservation assemblies provide for dynamic stabilization of the spinal motion segment. Other variations and implementations of the teachings are disclosed, including the sheathed delivery of membranes in order to protect the membranes before and during deployment.

An elongated durable corrosion resistent dishwasher accessory for securing and supporting stemware in a dishwasher rack. At one end of the dishwasher accessory is a C-shaped clip for connecting to a horizontal wire stringer on a dishwasher rack. At that same end of the dishwasher accessory is a bore that allows a vertical wire stringer to pass within the bore to secure the dishwasher accessory to the dishwasher rack. At the opposite end of the dishwasher accessory is two oppositely positioned gripper jaws with various sized bores therein. These bores clip around the stem of a piece of stemware, which secures the stemware in a vertical downward position within a dishwasher rack when the dishwasher accessory is secured to the wire stringer. This allows the washing streams of water to securely wash the liquid retaining portion of the stemware without upsetting or turning over the stemware in the dishwasher rack. The dishwasher accessory adjusts to different size and different heights of stemware, is durable, simple to construct, and easy to operate.
