    Abstract: Disclosed are methods and apparatus for the provision of spinal therapy to two or more adjacent motion segments accessed through a trans-sacral approach. The spinal therapies include fusion and dynamic stabilization with and without a distraction of the most cephalad motion segment of the two or more adjacent motion segments provided therapy. The disclosure includes methods and apparatus to impart a push distraction to increase the distance between two adjacent vertebrae. Related concepts for the extraction of previously inserted devices and the delivery and removal of plugs for plugging the interior cavities of implantable devices are disclosed.

    Abstract: Disclosed are surgical tools, tool sets and methods for percutaneously accessing and preparing treatment sites within the spine for subsequent treatment procedures. The treatment site may be avertebral motion segments in the lumbar and sacral regions of the spine. The tool set may a retraction device for retracting bowel from a sacrum. The device can induce a collapsible enclosure that defines a chamber. The collapsible enclosure can have a collapsed configuration and an expanded configuration. In some arrangements, the chamber is filled with an inflation media. The expanded configuration defines a working channel positioned between the sacrum and the bowel and extending over or through at least a portion of the device.

    Abstract: Methods and apparatus for providing percutaneous access to the presacral space in a minimally invasive, low trauma, manner. A number of related methods and surgical tool sets form a percutaneous pathway from an incision through the patient's skin adjacent to the coccyx and inserting an elongated guide assembly through the incision to locate the guide assembly against the anterior surface of the sacrum to access a presacral target point. The provision of the percutaneous pathway described herein allows for the introduction of therapeutic devices or media, diagnostic instruments, and/or drug delivery to the presacral space.

    Abstract: Surgical tools, tool sets and methods for percutaneously accessing and preparing treatment sites within the spine. A method of treating the spine, comprising the steps of percutaneously accessing an anterior target site on the surface of the sacrum, forming a lumen from the access site through the sacrum, through a disc and into at least one vertebra, advancing a fusion device comprising a distal portion, a proximal portion and an intermediate portion between the distal and proximal portion through the anterior target site on the surface of the sacrum and into the spine, rotating the distal portion of the device into a superior vertebral body and the proximal portion of the device in an inferior vertebral body to increase a distance between the superior and inferior vertebral bodies, and inserting through a percutaneous access site a posterior column fixation device into the spine.
