    摘要： An implantable spacer for placement between adjacent spinous processes in a spinal motion segment is provided. The spacer includes a body defining 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. An actuator assembly is disposed inside the longitudinal passageway and connected to the body. When advanced, the actuator assembly contacts camming surfaces of the arms to rotate them from an undeployed configuration to a deployed configuration. In the deployed configuration, the distracted adjacent spinous processes are seated in the U-shaped portion of the arms providing sufficient distraction to open the neural foramen. An insertion instrument is provided for implanting the interspinous process spacer. The system is configured for implantation through a small percutaneous incision employing minimally invasive techniques.

    摘要： A percutaneous and minimally invasive instrument for inserting an interspinous process spacer into a patient is disclosed. The insertion instrument includes a first assembly connected to a handle assembly. The first assembly includes an inner shaft located inside an outer shaft and configured for relative translational motion with respect to the outer shaft. The relative translational motion causes one of the outer or inner shafts to move with respect to the other and thereby deflect at least one prong formed on one of the inner or outer shafts wherein such deflection causes engagement with a juxtapositioned interspinous spacer. The instrument further includes a driving tool configured for removable insertion into a proximal end of a passageway of the instrument.

    摘要： An implantable spacer for placement between adjacent spinous processes in a spinal motion segment is provided. The spacer includes a body defining a longitudinal axis and 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 proximal caming surface and is capable of rotation with respect to the body. An actuator assembly is disposed inside the passageway and connected to the body. When advanced, a threaded shaft of the actuator assembly contacts the caming surfaces of arms to rotate them from an undeployed configuration to a deployed configuration. In the deployed configuration, the distracted adjacent spinous processes are seated in the U-shaped portion of the arms.

    摘要： An implantable spacer for placement between adjacent spinous processes is provided. The spacer includes a body and a wing rotatably connected to the body. The wing includes two U-shaped configurations that together define a substantially H-shaped configuration for retaining the spacer between adjacent spinous processes. An actuator assembly is connected to the body and to the wing with the proximal end of the spacer being connectable to a removable driver that is configured to engage the actuator assembly. While connected to the spacer, the driver is rotatable in one direction to deploy the wing from an undeployed to a deployed configuration and in an opposite direction to undeploy the wing. In the deployed configuration, the spacer acts as a space holder opening up the area of the spinal canal, maintaining foraminal height, reducing stress on the facet joints and relieving pain for the patient.

    摘要： A dilator that facilitates implantation of an interspinous spacer is provided. The dilator includes a proximal portion and a tapered distal portion interconnected by an elongated body portion. The tapered distal portion is ideally suited for splitting ligamentous tissue for creating a posterior midline pathway through the supraspinous ligament as well as for distracting the adjacent spinous processes. Two oppositely located and longitudinally extending channels or grooves are formed in the outer surface of the dilator for stabilizing the dilator with respect to the spinous processes. An accompanying cannula together with the dilator form a system for the distraction of the adjacent spinous processes, stabilization of the spinous processes with respect to the system and creation of a working channel for the implantation of an interspinous spacer.
