A bone material dispensing device is provided. The bone material dispensing device comprises a housing having a proximal end, a distal end, and a longitudinal axis. The proximal end having a first opening and the distal end having a second opening. The first opening and the second opening configured to slidably receive at least a portion of a plunger. A locking member is provided that is pivotably connected to an upper surface of the housing and extends adjacent to the upper surface of the housing. The locking member comprises a locking surface extending adjacent to the distal end of the housing configured to engage a portion of a tubular member, a funnel, or a combination thereof. The locking member is movable in a locking position to lock the portion of the tubular member, the funnel, or the combination thereof with the housing. A bone material dispensing system and a method of implanting bone material with the bone material dispensing system are also provided.

A unitarily formed expandable spinal implant for insertion in a disc space between two adjacent vertebrae. The unitarily formed expandable spinal implant is moveable from an unexpanded configuration to an expanded configuration, and can be manufactured by a 3-dimensional printer. The unitarily formed expandable spinal implant includes an upper portion, a lower portion, a proximal wall, a first distal wall portion, a second distal wall portion, and a separator connected by at least one point of attachment to the spinal implant. A separation tool breaks the separator free from the at least one point of attachment, and moves the separator within the implant to force expansion thereof from the unexpanded configuration to the expanded configuration.

A surgical instrument comprises a first member including an inner surface defining a passageway and a lock. A second member is disposable within the first passageway. The second member comprises an inner surface defining a passageway and extending between a first end comprising a lock and a second end configured to engage tissue. A third member is disposable within the second passageway. The third member extends between a first end and a second end configured to penetrate tissue and form a cavity therein. The first lock is engageable with the second member to prevent relative movement of the second member and the second lock is engageable with the third member to prevent relative movement of the third member. Systems and methods are disclosed.

Surgical instrument and method

This invention relates to devices and instruments for implant insertion through a posterior lateral opening to the disc space. The instruments include an implant inserter, and the devices include a spinal fusion implant engageable by the implant inserter. The implant provides bilateral support of the adjacent vertebrae when inserted into the disc space from a postero-lateral approach.

Devices and techniques for a posterior lateral disc space approach

A spinous process implant with two plates that are connected together with a post. The implant is configured for each plate to be positioned on outer lateral sides of spinous processes with the post extending through the interspinous space. One or both plates may be movable along the length of the post to accommodate different anatomies such as for relatively wide or thin spinous processes. The post includes an enlarged head at a first end to prevent the first plate from disassociating from the post in a first direction. The post also includes a boss at a second end to prevent the second plate from disassociating from the post in a second direction. Methods of attaching the implants to the spinous processes are also disclosed.

Methods and instrumentation particularly adapted for disc space preparation for insertion of implants from an anterior approach to the spine are provided. The instruments include a guide sleeve defining a channel having overlapping cylindrical working channel portions and lateral non-distracting extensions extending from reduced thickness wall portions. The guide sleeve has an overall reduced width configuration. A pair of distractors are provided. A first distractor includes a shaft and distal tip, each having convex walls. A second distractor includes a shaft and distal tip including a recessed area at least along the tip. The first distractor is at least partially received within the recessed area of the second distractor when the first and second distractors are in side-by-side relation and a reduced overall width of the distractors is obtained. Preferably, the first and second distractors are used with the guide sleeve. Methods using the disclosed instruments are also provided.

Methods and instrument for vertebral interbody fusion

A retractor assembly for percutaneous surgery in a patient that includes first and second retractor portions positionable opposite one another in an incision of the patient. A working channel extends between the first and second retractor portions and provides access to a location within the patient adjacent to distal ends of the first and second retractor portions. The first and second retractor portions are movable relative to one another to adjust the size of the working channel. An add-on retractor element is provided that is mounted to the first and second retractor portions and spans the gap between the first and second retractor portions to prevent creep of soft tissue into the working channel when the retractor portions are separated.

Add-on retractor element for retractor system

Instruments and techniques separate or spread adjacent bony structures by inserting a distal spreader assembly into the space between the adjacent bony structures and actuating the spreading members with a proximal actuator assembly.

A vertebral replacement device for supporting adjacent vertebrae includes a vertebral body member having at least one of an upper or lower disc replacement member engaged thereto at one end thereof. The disc replacement device can be positioned in a spinal disc space when disengaged from the vertebral body member.

Vertebral body and disc space replacement devices

Instruments and methods are provided for re-positioning and extracting spinal implants in a space between vertebrae. The instruments can include rotater instruments, hook instruments, and extractor instruments engageable to the implant. The extractor instruments can include a shaft assembly, an actuator assembly at a proximal end of said shaft assembly, and an engaging assembly at a distal end of the shaft assembly. The engaging assembly includes a support member fixedly coupled with and extending distally from the shaft assembly and a clamping member coupled with at least one of the shaft assembly and the support member. The actuator assembly is operably linked to the clamping member with the shaft assembly to move the clamping member toward the support member with the actuator assembly.
