摘要： Devices, systems and methods for dynamically stabilizing the spine are provided. The devices include an expandable spacer having an undeployed configuration and a deployed configuration, wherein the spacer has axial and radial dimensions for positioning between the spinous processes of adjacent vertebrae. The systems include one or more spacers and a mechanical actuation means for delivering and deploying the spacer. The methods involve the implantation of one or more spacers within the interspinous space.

摘要： A dynamic rod implantable into a patient and connectable between two vertebral anchors in adjacent vertebral bodies is provided. The dynamic rod fixes the vertebral bodies together in a dynamic fashion providing immediate postoperative stability and support of the spine. The dynamic rod comprises a first rod portion and a second rod portion connected together. The dynamic rod further includes at least a one bias element configured to provide a bias force in response to deflection or translation of the first rod portion relative to the second rod portion. The dynamic rod includes a locking construct which advantageously enables the extension and/or angulation of one rod portion with respect to the other rod portion to be reversibly locked in position. The dynamic rod permits relative movement of the first and second rod portions allowing the rod to carry some of the natural flexion and extension moments of the spine.

摘要： A tissue splitter for creating a subcutaneous cut is disclosed. The tissue splitter is insertable into a slotted cannula that is placed via an incision to a location proximate a patient's spine. An actuator at the proximal end of the instrument projects the blade located at the distal end from its retracted state through the slot of the cannula to an extracted state to subcutaneously cut tissue at a location outside the cannula. The blade is movable inside the slot of the cannula by a distance such that the cut created by the blade remains subcutaneous and does not puncture the skin of the patient. The distance is adjustable for the length of the cut and is limited by an adjustment collar. The tissue splitter is ideally suited for creating a pathway for the subcutaneous implantation of a spinal stabilization rod between two bone anchors placed in vertebral bodies.

摘要： A novel implantable spacer for placement between adjacent spinous process es in a spinal motion segment is provided. The spacer includes a body defini ng a longitudinal passageway. A first arm and a second arm are connected to the body. Each arm has a pair of extensions and a saddle defining a U-shaped configuration for seating a spinous process therein. Each arm has a proxima l camming surface and is capable of rotation with respect to the body. An ac tuator assembly is disposed inside the longitudinal passageway and connected to the body. When advanced, the actuator assembly contacts the camming surf aces of the arms to rotate them from an undeployed configuration to a deploy ed configuration. In the deployed configuration, the distracted adjacent spi nous processes are seated in the U-shaped portion of the arms providing suff icient distraction to open the neural foramen to relieve pain. An insertion instrument is provided for implanting the interpsinous process spacer. The s ystem is configured for quick implantation through a small percutaneous inci sion employing minimally invasive techniques.
