Method and apparatus for post-operative tuning of a spinal implant
A tunable implant, system, and method enables a tunable implant to be adjusted within a patient. The tunable implant includes a securing mechanism to secure the implant in the patient, a actuation portion that enables the implant to move and an adjustment portion that permits adjustment of the implant after the implant has been positioned within the patient. The method of adjusting the tunable implant includes analyzing the operation of the implant, determining if any adjustments are necessary and adjusting the implant to improve implant performance. The implant system includes both the tunable implant and a telemetric system that is operable to telemetrically receive data from the tunable implant where the data is used to determine if adjustment of the tunable implant is necessary. The system also includes an instrument assembly that is used for performing spinal surgery where the instrument assembly includes a mounting platform and a jig.
Implant assembly
An implant assembly smoothly causes a folded implant to indwell a living body, and which can smoothly expand the implant without causing the implant to be displaced from a predetermined indwelling position when a filling material is injected. The implant assembly has the implant that is configured to be transformable from a folded and contracted state to an expanded state by the introduced filling material, and in which at least a portion of a surface thereof is covered with a covering material m whose friction coefficient increases by coming into contact with a body fluid, and guiding means for preventing the implant and the body fluid of the living body from coming into contact with each other inside the living body, and for guiding the implant to move to the indwelling position inside the living body.
Cortical Rim-Supporting Interbody Device
A central inflatable distractor and a perimeter balloon are inserted into the disc space in uninflated configurations. The central inflatable distractor is then expanded, thereby distracting the vertebral endplates to the controlled height of the central inflatable distractor. The perimeter balloon is then inflated with a curable substance. The perimeter balloon expands as it is filled with the curable substance and conforms to the void remaining in the disc space around the central inflatable distractor, thereby creating a horseshoe shape. Once the flowable material in the perimeter balloon has cured, the central inflated distractor can be deflated and removed. The remaining void (or inner space) is then packed with graft for fusion.
INTERSPINOUS DYNAMIC IMPLANT
The present invention relates to an interspinous dynamic implant. Provided is an interspinous dynamic implant comprising: an upper plate which adheres to an upper spinous process; a lower plate which adheres to a lower spinous process; a movable part, coupled between the front portion of the upper plate and the front portion of the lower plate, for enabling the upper plate and the lower plate to move upwards, downwards, left and right within a certain range according to the movement of spinous processes; an upper spinous process coupling means for tightly coupling the upper plate to the upper spinous process; and a lower spinous process coupling means for tightly coupling the lower plate to the lower spinous process. The interspinous dynamic implant according to the present invention provides elasticity to the upper spinous process and the lower spinous process, thereby maintaining a space between the upper and lower spinous processes. Also, the interspinous dynamic implant moves by being integrated with the upper and lower spinous processes, and thus does not damage the spinous processes and has an effect of preventing a separation phenomenon from between the spinous processes. Further, the interspinous dynamic implant can move together with adjacent spinous processes according to the upward, downward, left and right movements of the adjacent spinous processes, and thus enables the movement of the upper spinous process and the lower spinous process to be more natural compared to conventional implants, thereby having an effect of not giving a burden to the spine. Also, the interspinous dynamic implant has an effect of enabling minimally invasive surgery since blades can be rotated and tightened using an instrument after inserting the interspinous dynamic implant from the side surface of spinous processes. Furthermore, after inserting the interspinous dynamic implant between adjacent spinous processes and tightening the blades at both side surfaces of the spinous processes, a plurality of spikes provided in the blades are tightly embedded in the both side surfaces of the spinous processes, and thus there is an effect that an upper blade and a lower blade are stably coupled to the upper and lower spinous processes. In addition, since the interspinous dynamic implant can be inserted between the spinous processes in a state where the upper blade and the lower blade are folded, the blades do not catch on the upper and lower spinous processes during insertion, and thus there is an effect that the interspinous dynamic implant can be inserted not only from the rear side of the spinous processes but also from the side surface of the spinous processes.
HEIGHT RESTORING DEVICE, INSERTION APPARATUS HAVING A HEIGHT RESTORING DEVICE AND METHOD FOR RESTORING THE HEIGHT OF AND STABILISING THE SPINAL COLUMN
The invention relates to a height restoring device for restoring the height of and stabilizing the spinal column, in particular for stabilizing broken vertebral bodies or contused intervertebral discs, which device can be arranged in an insertion position in a compression-fractured vertebral body or between adjacent vertebral bodies and once there, can be transferred from the insertion position into an expansion position by means of an expansion apparatus.
FLEXIBLE ANCHORING AND FUSION DEVICES AND METHODS OF USING THE SAME
A spacer member is provided that is configured to be implanted adjacent an anatomical structure. The spacer member defines a curved bore, a first opening in a side wall of the spacer member and a second opening in one of a top wall and a bottom wall of the spacer member. Each of the first opening and the second opening are in fluid communication with the curved bore. A flexible anchoring member is configured to be inserted through the side opening and through the curved bore of the spacer member such that a distal end portion of the flexible anchoring member extends out of the second opening at an angle relative to the one of the top wall and the bottom wall of the spacer member.
Expandable motion preservation spacer
Embodiments are directed to an expandable spacer for insertion between two adjacent bony structures or two adjacent joint surfaces, and more particularly relate to an expandable spacer for insertion into the void remaining in the intervertebral space. Embodiments may include an expandable spacer comprising a first endplate; a second endplate spaced from the first endplate; and one or more bags disposed between the first endplate and the second endplate that couple the first endplate to the second endplate. The one or more bags may be configured to receive a filler material to expand the expandable spacer from an initial position having a first height to an expanded position having a second height, wherein the second height is greater than the first height.
EXPANDABLE INTERBODY IMPLANT WITH LORDOSIS CORRECTION
A spinal implant for placement between vertebral bodies includes a first member for engaging one of the vertebral bodies, a second member for engaging an opposing one of the vertebral bodies, and at least one extendable support element for inducing movement of the entire first member away from the second member. The first member is connected to the second member such that the first member moves away from the second member by a larger distance at a first end of the implant than at a second end of the implant. A connecting member may connect the first and second members together at the second end of the implant. The connecting member may include one or more rotatable linkages, or the connecting member may be an extension of one of the first and second members slidably received within a track defined within the other of the first and second members.
Spinal tissue distraction devices
Spinal tissue distraction devices that include a member which has a pre-deployed configuration for insertion between tissue layers and a deployed configuration in which the member, by change of configuration, forms a support structure for separating and supporting layers of spinal tissue.
