Abstract
Instrumentation and method for treatment of a spinal structure, comprising an elongate member including a deformable distal portion having an initial configuration for placement within the spinal structure and a deformed configuration wherein the distal portion is outwardly deformed to form a cavity in the spinal structure. The elongate member comprises a cannula member and an actuator member that is removably positioned within the cannula member and configured to transition the deformable distal portion from the initial configuration toward the deformed configuration. The actuator member is selectively removed from the cannula member to provide a passageway for delivery of a material into the cavity formed in the spinal structure.

35. A method for treatment of the spine, comprising:
-
providing an instrument defining a cannula passage extending along a longitudinal axis and including a deformable distal portion having an insertion configuration and a deformed configuration;
positioning the distal portion of the instrument within a spinal structure while in the insertion configuration;
transitioning the distal portion of the instrument toward the deformed configuration and forming a cavity within the spinal structure; and
delivering a material through the cannula passage and into the cavity in the spinal structure. - View Dependent Claims (36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60)
