    摘要: A burr hole sealing device for preventing brain shift during a stimulation lead implantation procedure is provided. The device includes a suction cup ring and a self-sealing membrane positioned within the aperture of the ring. The sealing device is attached adjacent to a burr hole and over a dura layer that is exposed in the bottom of the burr hole. The stimulation lead is disposed through the burr hole, through the membrane, through the dura layer and into brain tissue. The membrane is configured to allow the lead to pass therethrough while maintaining a tight seal around the diameter of the lead, thereby hindering leakage of cerebrospinal fluid out of the cranial cavity and maintaining a substantially fixed intracranial pressure. In one embodiment, the sealing device includes a syringe for adding fluid to, or removing fluid from, the cranial cavity in response to a detected change in intracranial pressure.
