An insertion instrument for inserting an implant includes an elongated main body having a proximal handle and a distal portion that selectively couples to the implant. A plunger is slidably engaged in a central passage of the elongated main body to fix the implant to the elongated main body. A hex nut driver is concentrically located about the plunger and elongated main body to deploy an actuation plunger of the implant. The proximal handle portion of the main body includes a staggered path therethrough for accepting a tab of the plunger therein. Advancement and retraction of the plunger tab within the staggered path alternates the insertion instrument between an unlocked position to mount the implant on the distal portion, a locked position to lock the implant on the distal portion, and a deployed position configured to secure the implant in position.

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.

An interspinous process device includes a first plate, a second plate, and a transverse member between the first plate and the second plate, wherein the second plate is adjustably coupled to the transverse member. A post is coupled to the transverse member and a spring mechanism is disposed between the post and the first plate. The spring mechanism is configured to provide a preloaded compression force to the first and second plates. Methods of implanting the interspinous process device using an inserter tool are also disclosed.

The present invention relates generally to implants and tools for the fixation or fusion of joints or bone segments. These tools include tissue dilators and protectors. Other tools include broaches used to shape bores in bone. The tools can also include a system for removing an implant from bone. Implants can include assemblies of one or more implant structures that make possible the achievement of diverse interventions involving the fusion and/or stabilization of lumbar and sacral vertebra in a non-invasive manner, with minimal incision, and without the necessitating the removing the intervertebral disc. Implants for fusing both sacroiliac joints of a patient include a long implant that extends across both sacroiliac joints.

A disposable insertion instrument for inserting an implant includes a handle assembly, a drive assembly, and a plunger assembly. The drive assembly comprises an inner shaft and a spring received within an outer sleeve. A locking pin and drive lobes on the inner shaft cooperate to reversibly lock the drive assembly in a retracted position. A medical implant may be attached to the instrument via an adapter located at a distal end of the drive assembly. Following insertion of the medical implant into a patient, the disposable insertion instrument may be discarded.

An implantable device including an intervertebral wedge including an upper bearing zone and a lower bearing zone and at least one first lateral spring having a position A relative to the intervertebral wedge in a position for inserting the implantable device and a position B relative to the intervertebral wedge in a position for implanting the implantable device, the positions A and B being different and the first lateral spring being configured: to freely translate from position A to position B and to form a retention component arranged relative to the intervertebral wedge to block the migration of the intervertebral wedge toward the spinal canal in position B.

A system and method for providing a surgical instrument having a shaft with a proximal end, a distal end, a longitudinal axis, and a central lumen extending therethrough; and a tapered head at the distal end. The tapered head has a plurality of longitudinal channels, a plurality of threaded sections, and a plurality of lateral lumens. The plurality of longitudinal channels may form a plurality of flutes configured to cut bone, tissue, or both.

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.

A system and method for providing a spinal implant having a main body, a proximal anchor, a distal anchor, and an internal plunger. The proximal anchor comprises a nut having an internal bore. The distal anchor comprises a plurality of wings having a first closed configuration and a second open configuration. The internal plunger is housed within a central bore of the main body. The distal end of the internal plunger is operatively connected to the first wing and the second wing to selectively move the wings between the first closed configuration and the second open configuration, and vice versa.

An interspinous process spacer includes a main body, a first wing, and a screw. The main body includes a first securing member extending from a top portion of the main body that engages a first vertebra and a bottom portion of the main body that engages a second vertebra. The first wing pivotably couples to a distal portion of the main body and includes a second securing member extending parallel to the first securing member to form a first clamp. The screw is positionable within the main body and includes a distal end that positions the first wing between a first position and a second position. The first clamp includes a first diameter in the first position and a second diameter in the second position.
