Abstract: A spinal disc nucleus pulposus implant is provided which includes a biocompatible material that is injectable into an intradiscal space in a fluid state below physiological temperatures, and that is curable by temperature alone via a reversible phase shift to form a gel at physiological temperatures.

Abstract: An ultrasonic emitting apparatus (10) for cauterizing and ablating tissue. Ultrasonic waves are focused at an intended region of operation by an elongated waveguide (15), thus reducing damage to adjacent unintended tissue. The waveguide (15) can be inserted into structures of the body through overlying organs. The device may be used, for example, to ablate protruding portions of spinal disks.

Abstract translation: 一种用于烧灼和消融组织的超声波发射装置（10）。 超声波通过细长的波导（15）聚焦在预定的操作区域，因此减少了对相邻非预期组织的损伤。 波导（15）可以通过上覆的器官插入身体的结构中。 该装置可用于例如烧蚀脊椎盘的突出部分。
