| 发明名称 | Intervertebral disc treatment apparatus | ||
| 摘要 | A method of at least partially removing the nucleus pulposus of an intervertebral disc comprising the nucleus and an annulus surrounding the nucleus is described. The method comprises the steps of: insonating the nucleus with ultrasound thereby to cause at least partial fragmentation of the nucleus; and extracting at least part of the fragmented nucleus. A system for performing the method is also described. | ||

| 主权项 | 1. A method of at least partially removing the nucleus pulposus of an intervertebral disc comprising the nucleus and an annulus surrounding the nucleus, the method comprising the steps of: injecting pressure resistant cavitation nuclei into the nucleus; insonating the nucleus including the pressure resistant cavitation nuclei with ultrasound thereby to cause at least partial fragmentation of the nucleus; and extracting at least part of the fragmented nucleus. | ||
