Abstract
A device that can be placed within or near the cranial vault that fluctuates in size in response to changes in CSF pressure is disclosed. The device diminishes in size when CSF pressures rise and increases in size as CSF pressures diminish. The device has the effect of reducing the flow of CSF occurring in the foramen magnum and provides an alternative to craniovertebral decompression in Chiari I patients. The device may have applications in other neurologic illnesses associated with abnormal CSF flow, such as Idiopathic Syringomyelia, Normal Pressure Hydrocephalus, and CSF dural leaks.

1-20. (canceled)
A device comprising:
- a component having a variable component volume and capable of being installed either adjacent to or into a fluid space within a human cranial vault, the human cranial vault having an intracranial pressure;
- wherein the component comprises a flexible material that changes the component volume based on fluctuations in the intracranial pressure;
- wherein the component volume decreases when the intracranial pressure increases, thereby adding to the capacity of the human cranial vault and reducing additional increases of intracranial pressure;
- and
- wherein the component volume increases when the intracranial pressure decreases, thereby decreasing the capacity of the human cranial vault and reducing additional decreases of intracranial pressure.
