Surgical Instrumentation and Method for Treatment of a Spinal Structure
First Claim
1. Instrumentation for treatment of the spine, comprising:
- an elongate member extending along a longitudinal axis and including a flexible and elastically deformable distal portion having an initial configuration for placement within a vertebral body and an elastically deformed configuration wherein said distal portion is outwardly deformed, said elongate member comprising a cannula member and an actuator member, said cannula member sized to extend into a vertebral body of the spine, said actuator member being removably positioned within said cannula member and configured to transition said deformable distal portion from said initial configuration toward said elastically deformed configuration by imposition of an axial compression force onto said deformable distal portion, said actuator member being selectively removed from said cannula member to provide a passageway for delivery of a material into the vertebral body.

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.

13. Instrumentation for treatment of the spine, comprising:
- an elongate member extending along a longitudinal axis and including a deformable distal portion having an initial configuration for placement within a vertebral body of the spine and a deformed configuration wherein said distal portion is outwardly deformed, said elongate member comprising a cannula member and an actuator member, said cannula member sized to extend into the vertebral body, said actuator member being removably positioned within said cannula member and configured to transition said deformable distal portion from said initial configuration toward said deformed configuration, said actuator member being selectively removed from said cannula member to provide a passageway for delivery of a material into the vertebral body; and
wherein relative displacement between said actuator member and said cannula member results in axial compression of said deformable distal end portion to transition said deformable distal end portion toward said deformed configuration. - View Dependent Claims (14, 15)

16. Instrumentation for treatment of the spine, comprising:
-
an actuator member extending along a longitudinal axis and including a flexible and elastically deformable distal portion having an initial configuration for insertion into a vertebral bone of the spine and a mechanically and elastically deformed configuration; means for defining through passage in the vertebral bone for receipt of the actuator member; means for mechanically deforming said distal portion from said initial configuration toward said mechanically and elastically deformed configuration by imposition of an axial compression force onto said deformable distal portion; and means for delivering a material into the vertebral body through the means for defining through passage. - View Dependent Claims (17, 18, 19, 20)
