Abstract: A method and apparatus can include: a delivery tool having an insertion mandrel; an implant having a distal segment coupled to a proximal segment, the proximal segment having a proximal segment upper and a proximal segment lower, the distal segment having a distal segment upper and a distal segment lower, the implant including: a straight configuration based on the insertion mandrel being extended through the proximal segment and the distal segment, and a curved configuration based on the insertion mandrel being retracted from the distal segment; and an expansion mandrel configured for insertion into the implant, the implant including an expanded configuration based on the expansion mandrel being inserted between the proximal segment upper and the proximal segment lower, and being inserted between the distal segment upper and the distal segment lower.

Abstract: A super-elastic implant system and method can include: a rigid mandrel; and an implant including a main body in the shape of a tube, the main body formed of a shape set material configured to have: a stress induced martensitic phase in a deformed shape having a straight end, the deformed shape based on the main body being constrained on the mandrel, and an austenitic phase having a non-linear curve, the non-linear curve in the location of the straight end, and the austenitic phase based on the main body being removed from the mandrel.

Abstract: A spinal fusion system method and apparatus can include: providing segments including a first segment and a second segment; and coupling the first segment to the second segment with a flexible member, the flexible member configured to have a deformable state based upon a temperature of the flexible member being below a transition temperature range or based upon a stress being applied to the flexible member, and the flexible member configured to enter a shape-set state from the deformable state based on the temperature of the flexible member rising above the transition temperature range, or based upon the stress being removed from the flexible member and the temperature of the flexible member being above the transition temperature range.

Abstract: Apparatus and method used to reduce the movement between vertebrae or fractured bones. The implantable device can be deformed from its shape-set configuration for ease of deployment and return to a pre-set shape upon completion of deployment. The apparatus can serve to stabilize fractured bones or as a distraction device and support structure between vertebrae. Device may be made of a material with shape memory and superelastic properties which facilitate the method of implantation. The pre-set shape of the device may include dimensions/geometries which are similar to the natural curvature of the human spine or bone without the use of hinging or connection between multiple pieces. Once deployed, the device can serve to constrain the flow of bone growth material between the inside and outside of the device.
