  • Patent number: 5484445
    Abstract: A simple and reliable system for anchoring a lead to the sacrum. The system provides a pliant slid-on anchoring sleeve featuring a suturing groove for lead fixation and a base having screw tabs for anchoring the sleeve and thus the lead to the sacrum. The base is reinforced, preferably through a mesh, to prevent tearing caused by screw forces. In addition an elongate washer may be further used in conjunction with screws to anchor the system to bone.

  • Patent number: 5352194
    Abstract: The present invention provides a device for performing suction lipectomy or liposuction in which the reciprocal motion required during the liposuction procedure is automated. This automation greatly reduces the physical exertion required of the operating surgeon. The present invention also allows the use of smaller cannulae to achieve an improved aesthetic result. Use of such smaller cannulae with the manual liposuction procedures currently in use would be extremely taxing if not impossible.

  • Patent number: 5313962
    Abstract: In one method for performing a laparoscopic lumbar discectomy an incision is created in the abdominal wall of a patient. The peritoneal lining is dissected from the abdominal wall while relocating the peritoneal lining toward the midline of the abdomen to create an expanded retroperitoneal space. A surgical apparatus is inserted into the incision comprising an endoscope and surgical means suitable for performing a lumbar discectomy. The surgical apparatus is directed through the expanded retroperitoneal space until the surgical apparatus approaches the anterior aspect of a vertebral body and a discectomy is performed on the vertebral body.
