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.
Claims6
A method of treating a patient, comprising:
- diminishing cerebrospinal fluid oscillatory flow by:
- inserting a tube jacket having a distal end and a proximal end through the scalp and the skull of the patient, wherein a balloon having a balloon aperture surrounds the distal end of the tube jacket;
- selectively inserting and removing a trochar through a hemostasis valve, a trochar lumen and a lateral ventricular space within the patient;
- installing the proximal end of the tube jacket and a balloon reservoir in between the skull and the scalp of the patient;
- and
- removing the trochar from the trochar lumen;
- wherein a balloon lumen protrudes from the proximal end of the tube jacket, running through the tube jacket from the proximal end of the tube jacket through the distal end of the tube jacket and ending at the balloon aperture;
- wherein the trochar lumen runs from the proximal end of the tube jacket through the distal end of the tube jacket and protrudes from the distal end of the tube jacket;
- wherein the hemostasis valve connects to the proximal end of the trochar lumen.
