A discectomy tool comprising: a) a cannula having an outer surface having a longitudinal bore therein, a proximal end and a distal end; b) a steering wire disposed in the longitudinal bore; c) a flexible, hollow transmission shaft disposed in the cannula, the shaft having a throughbore, a proximal end portion, a distal end portion and an outer surface having a thread extending therefrom; d) an irrigation source fluidly connected to the throughbore; e) a cutting tip attached to the distal end portion of the transmission shaft.

A steerable system and methods for accessing bone. A control mechanism includes a handle configured to be detachably secured to a trocar. The handle includes a drive shaft coupled to a sliding shaft such that relative rotation is prevented and relative translation is permitted. A rod having a preformed bend is removably disposed within the cannula. The rod is prevented from rotating relative to the drive shaft such that a deflection plane of the preformed bend is predefined relative to each of the sliding shaft, the handle, and the trocar when the handle is coupled to the trocar. Rotating a sliding ring of the handle translates the drive shaft to advance the rod beyond the trocar such that the preformed bend extends laterally out of the trocar in the deflection plane. The rod may be removed from the cannula, and material may be injected through the cannula.

A device for percutaneous transpedicular fusion includes at least two straight pedicular cannulas arranged respectively on the upper or lower vertebra, or on the two vertebrae of the spinal segment, at least one guide pin with a curved profile, which is implanted in the endplate of the corresponding vertebra through the corresponding pedicular cannula, of a flexible cannulated drill bit guided around the corresponding guide pin and driven in back and forth movements by a cannulated drive system to nibble out gradually slots in the lower and upper endplate of each vertebra and reduce to flaps the nucleic tissues of an intervertebral disk for the production of the intersomatic space, of an injection device connected to one of the straight pedicular cannulas for the injection of the graft into the intersomatic space, and closing devices that are screwed into the holes left free after retraction of the straight pedicular cannulas.

Systems and methods of delivering and deploying a stent into a curvilinear cavity within a vertebral body or other bony or body structure. In some instances, the system can include an elongate shaft for delivering a self-expanding, cement-directing stent and devices that may be used to perform the steps to deliver and deploy the stent.

A device is disclosed that includes a bone stent positioned within a bony access channel formed within a vertebra. The bony access channel may extends from an outer end of the vertebra through an endplate. The device includes an end cap attached to a proximal end portion of the bone stent and is configured to, post-operatively, open to allow a reintroduction of a material to a spinal intradiscal space or intervertebral disc and to seal access to the spinal intradiscal space or the intervertebral disc after the reintroduction of the material.

Described herein are examples of adjustable orthopedic reamer heads and methods for preparing a bone to receive an implant. The adjustable reamer heads and methods can include changing a cutting characteristic such as the size of an adjustable reamer head. In an illustrative example of an adjustable reamer head, the reamer head can include a housing, an actuator and a plurality of cutting elements. The plurality of cutting elements can be retained by the housing and can be operably coupled to the actuator. The plurality of cutting elements can include a first size cutting element and a second size cutting element. When the actuator is actuated, the first size cutting element and the second size cutting element can move relative to one another to change from a first cutting size to a second cutting size.

System and methods for channeling a path into bone include a trocar having a proximal end, distal end and a central channel disposed along a central axis of the trocar. The trocar includes a radial opening at or near the distal end of the trocar. The system includes a curveable cannula sized to be received in the central channel, the curveable cannula comprising a curveable distal end configured to be extended laterally outward from the radial opening in a curved path extending away from the trocar. The curveable cannula has a central passageway having a diameter configured allow a probe to be delivered through the central passageway to a location beyond the curved path.

A surgical device capable of interconnecting to an external motorized hand pieces, bending a distal end segment, rotating a window element positioned distal to the distal end segment and rotating independently of it, and actuating a cutting element positioned within the outer window element and rotating independently of it.

A method and apparatus for coupling a soft tissue implant into a locking cavity formed within a bone is disclosed. The apparatus includes a member to pull the soft tissue implant into a femoral tunnel. The member includes a suture having first and second ends which are passed through first and second openings associated with the longitudinal passage to form a pair of loops. Portions of the suture lay parallel to each other within the suture, Application of tension onto the suture construction causes retraction of the soft tissue implant into the femoral tunnel.

Described herein are examples of orthopedic reamer heads for preparing a bone to receive an implant, as well as methods of assembling reamer heads. An illustrative example of a modular reamer head can include a body and a cutting system. The body can include a generally dome shape having an outer surface extending from an apex region to a base. The outer surface can have a recess including one or more arcuate channels that extend from the apex region towards the base of the dome. The cutting system can have one or more arcuate elements having cutting elements. One or more arcuate elements can extend from first end portions in the apex region towards second end portions proximate the base. At least a portion of the one or more arcuate elements can be located in the one or more arcuate channels to extend outward beyond the outer surface.
