An access port for minimally invasive surgery includes an elongate, tubular main body portion, a connector configured to fix at least a portion of the access port to a stationary object; and a slot extending over a length of the main body portion in a lengthwise direction, wherein the slot extends through a wall of the main body portion, from an outside surface of the main body portion to an inside surface of the main body portion.

An expandable implant for augmenting a damaged or otherwise torn posterior annulus fibrosus. The implant is deployable into an evacuated posterior disc space following a subtotal nuclectomy. The implant includes an inflatable balloon which is fixed to the annulus fibrosus to protect against migration. When inflated with a curable polymer, the posterior wall of the implant is intimately disposed along the inner surface of the annulus fibrosus to provide a substantially fluid-tight seal of the annular tear or defect and reinforce the weakened posterior annulus. The anterior wall of the implant sequesters the nuclear remnant to guard against disc remnant herniation. The implant can restore intradiscal pressure and disc height. An integrated posterior reinforcement band creates a strong, yet flexible and resilient structure, resistant to penetration of the implant through the annular tear or defect.

An intervertebral implant for implantation in an intervertebral space between vertebrae. The implant includes a body extending from an upper surface to a lower surface. The body has a front end, a rear end and a pair of spaced apart first and second side walls extending between the front and rear walls such that an interior chamber is defined within the front and rear ends and the first and second walls. The body defines an outer perimeter and an inner perimeter extending about the internal chamber. At least one of the side walls is defined by a solid support structure and an integral porous structure, the porous structure extending from the outer perimeter to the inner perimeter. The porous structure embeds or encapsulates at least a portion of the solid support structure.

A staged expansion of an intervertebral scaffolding system is provided, and also include a laterovertically-expanding frame operable for a reversible collapse from an expanded state into a collapsed state. The expanded state, for example, can be configured to have an open graft distribution window that at least substantially closes upon the reversible collapse.

The present invention relates to systems and methods for spinal fusion procedures that can allow all components of the spinal fusion procedure to be inserted into the wound of a patient at once, and can thus minimize the number of components that must be separately inserted into a wound. This can be accomplished by providing a intervertebral fixation system that allows an intervertebral cage and a vertebral fixation plate to be assembled into a single unit prior to insertion into a patient.

A spinal implant which is configured to be deployed between adjacent vertebral bodies. The implant has at least one fixation element with a retracted configuration to facilitate deployment of the implant and an extended configuration so as to engage a surface of an adjacent vertebral body and secure the implant between two vertebral bodies. Preferably, the implant is expandable and has a minimal dimension in its unexpanded state that is smaller than the dimensions of the neuroforamen through which it must pass to be deployed within the intervertebral space. Once within the space between vertebral bodies, the implant can be expanded so as to engage the endplates of the adjacent vertebrae to effectively distract the anterior disc space, stabilize the motion segments and eliminate pathologic spine motion. Angular deformities can be corrected, and natural curvatures restored and maintained.

Embodiments herein are generally directed to vertebral implants and implant trials for use with vertebral implant assemblies. In some embodiments, these implants and implant trials may be used in conjunction with corpectomy procedures.

The present invention is an implant for bone. The current implant is particularly useful in spinal surgical procedures.

An intervertebral spinal spacer system including a first portion of a modular spacer, the first portion having an upper surface, a lower surface, and an outer surface, and a second portion of the modular spacer, the second portion having an upper surface a lower surface, and an outer surface, wherein the first portion is selectively engageable with the second portion.
