摘要： A spinal implant device has a synthetic or metallic or a combination thereof of these materials in an implant body structure and stem cells in a coating, or a sheet, wrap or a membrane wrap applied to surfaces on the implant body structure or alternatively filled with a plug of stem cell laden material. The implant body structure preferably has an aperture or channel. The spinal implant device may include anchoring holes to secure the device to the spinal skeletal structure with fasteners or alternatively can simply be held in place by and between adjacent vertebrae.

摘要： A method and system for percutaneous fusion to correct disc compression is presented. The method has several steps, for instance, inserting a percutaneous lumbar interbody implant; positioning guide wires for each facet screw to be implanted; performing facet arthrodesis in preparation for the facet screws; fixating the plurality of facet screws; and optionally performing foramen nerve root or central decompression. The system includes an implant, an elongate cannulated insertion tool, and an elongate lockshaft positioned within the insertion tool.

摘要： Described herein are devices, systems and methods for treating target tissue in a patient's spine. In general, the methods include the steps of advancing a wire into the patient from a first location, through a neural foramen, and out of the patient from a second location; connecting a tissue modification device to the wire; positioning the tissue modification device through the neural foramen using the wire; modifying target tissue in the spine by moving the tissue modification device against the target tissue; and delivering an agent to modified target tissue, wherein the agent is configured to inhibit blood flow from the modified target tissue. In some embodiments, the step of modifying target tissue comprises removing target tissue located ventral to the superior articular process while avoiding non-target tissue located lateral to the superior articular process.

摘要： A detachable vertical cutter for insertion into a cylinder or tube is formed as a single unitary structure. The single blade has a pair of tool attachment end portions and a cutting blade extending in a loop between the attachment ends. The cutting blade is inclined vertically relative to a longitudinal axis of a cylinder or tube into which the attachment ends can slide into. The cutting blade has a cutting edge, a portion of which when extended free of the cylinder or tube will extend a distance greater than the tube outside diameter. The cutting edge when pushed inwardly and pulled outwardly between adjacent vertebrae scrapes and cuts disc material. When retracted the cutting blade deflects into the cylinder or tube for insertion or extraction into or from the disc space.

摘要： A bone anchor locking device for receiving a bone anchor having a shank and an enlarged head, the device has a bone anchor, a dome and a conical split washer. The receiving portion has a base extending radially outward and inwardly to a wall. The dome has a center aperture sized to pass a bone anchor. The split washer has an inner conical surface sloped to slide and expand against at least a portion of the base on insertion of a bone anchor to allow a maximum diameter of a head of a bone anchor to pass and thereafter the split washer retracts overlying the maximum diameter of the head to prevent a bone anchor from backing out.

摘要： An expandable interbody fusion implant device has a frame, two ramp assemblies and two overlying base plates driven by two independent drive shafts. The two ramp assemblies include a distal ramp assembly and a proximal ramp assembly. Each ramp assembly has a translating ramp, a first pivoting hinged ramp and a second pivoting hinged ramp. The two overlying base plates include a first base plate overlying a second base plate. Each base plate is hinged to the distal ramp assembly and the proximal ramp assembly at an end of one of said pivoting hinged ramps of each ramp assembly. The two independently driven drive shafts include a first drive shaft for translating the distal ramp assembly and a second drive shaft for translating the proximal ramp assembly to independently expand the implant proximally or distally or both.

摘要： A screw extension assembly for use in minimally invasive spinal surgery, the assembly has an inner slotted shaft and an outer shaft, a rod reducer and a removable nut. The combination when assembled is configured to move a spinal fixation rod into a slotted rod receiving spinal implant where it is seated and affixed thereto. The screw extension assembly further has a locking knob rotationally coupled to a proximal end of the outer shaft, wherein the inner shaft has one or more cam grooves and the locking knob has a pin extending into and guided by said cam groove causing the outer shaft to translate longitudinally upon rotation of the locking knob relative to the inner shaft toward an engaged position locking the deflectable legs in the coupled position to the slotted rod receiving implant.
