International Classification:

A61B 17/70

US Classification:

606249, 606248, 623 1711, 623 1716

Abstract:

An implantable spacer for placement between adjacent spinous processes is provided. The spacer includes a body and a wing rotatable 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.

US Classification:

606249, 623 1711

Abstract:

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.
