20090062619 | METHODS AND APPARATUS FOR SURGICAL RETRACTION - The present invention provides method and apparatus that may be patient mounted for surgical retraction. The retractor disclosed herein may be positioned with a base plate resting against the patient's skin surface. In one embodiment, retractor blades extending into the patient's body from the base plate of the retractor device may be adapted to be inserted in a closed position for minimally invasive access, and adapted to be moved away from each other in a controlled fashion to create the desired surgical retraction of soft tissue. Because the blades are inserted in a closed position, the skin incision is small compared to the available exposure of nerves and delicate tissue. | 03-05-2009 |
20100318134 | SYSTEM AND METHOD FOR PERFORMING PERCUTANEOUS SPINAL INTERBODY FUSION - A method of performing percutaneous interbody spinal fusion on adjacent vertebrae in a patient including the steps of: creating an access opening on the patient, the access opening being less than 10 mm wide, using indirect visualization: establishing a surgical path through the access opening via neural monitoring, creating a cavity in a disc space between the adjacent vertebra, evaluating the created cavity, inserting a container sized and configured to fit through the less than 10 mm access opening into the cavity and filling the container with fill material. | 12-16-2010 |
20100331882 | Anchorless Non-Invasive Force Dissipation System for Orthopedic Instrumentation - An anchorless non-invasive force dissipation device for orthopedic instrumentation including a base having a patient contacting surface, the patient contacting surface including a surface area adapted for external placement on a patient's body, and an instrument alignment mechanism operably connected to and selectively positionable relative to the base, the instrument alignment mechanism adapted to interface with at least one orthopedic instrument, such that forces applied by the orthopedic instrument are dissipated across the surface area of the base with the device being unanchored externally of the patient. | 12-30-2010 |
20110257691 | LOCKING CANNULATED BONE SCREW SYSTEM - A cannulated bone screw having a cannula or lumen defined herein is disclosed. The screw may be fully or partially threaded and may have a cancellous thread form. Alternatively, the head of the screw may be generally flat on its undersurface. The screw head may further include an anti-backout feature to ensure good contact with the mating bone surface. The screw may further include an anti-rotation feature on the underside of the screw head. It is further disclosed that insertion and seating of the screw may be accomplished via locking engagement between jaws on the screw driver and a short raised feature on the head of the screw. The screws may be fully or partially threaded. A rescue screw is additionally disclosed. | 10-20-2011 |
20130035691 | SURGICAL BRUSH - A stainless steel bristled surgical brush for removing nucleus material from the intervertebral space and cartilage from vertebral endplates is provided herein. The surgical brush of the present invention may be dimensioned to be placed through a minimally invasive and/or percutaneous access through an access portal. In certain embodiments, the surgical brush may be straight or bent, may include a cap to contain the tines and may include a depth stop. The brush may be manually operated, powered by a wire driver or powered by other suitable means. | 02-07-2013 |
20130066305 | MINIMALLY INVASIVE PORTAL SYSTEM - A minimally invasive surgical portal system, device and method may comprise a top ring assembly removably connected to an arm of a table mounted frame to provide stability and a secure trajectory. The portal system may include a top-ring assembly which may mount to an arm of a table mounted frame. The system may include a removable connection mechanism comprising a spring loaded collar configured to removably connect the top ring assembly to a table mounted frame. A variable adjustment positioner may be removably connected to the arm of the table mounted frame. The system may also include a depth positioning mechanism. The system may further include a light source configured to be placed down the portal tube. | 03-14-2013 |
20130079882 | FAR LATERAL SPACER - A PEEK spacer for use in the spine is disclosed. The PEEK spacer may be configured to fit through Kambin's Triangle and expand upon insertion. | 03-28-2013 |
20130158603 | INTERSPINOUS PROCESS SPACER - An interspinous process spacer is disclosed. The interspinous process spacer may be configured to be minimally invasive and adjustable. | 06-20-2013 |
