Spinal disc nucleus implant |
摘要 |
A device and method for repairing spinal discs in which the nucleus has been damaged. A central section of the nucleus is cored out using a device which ablates the tissue using RF energy. A nucleus implant comprising a shape memory material is placed in the central section of the disc through a cannula, which implant is activated by body heat to expand and fill the central section, such that the implant emulates the functions and strength of the disc's natural nucleus.
