Ventricular cerebrospinal fluid
(CSF) shunting remains the most prominent treatment of choice. CSF shunting
procedures provide a rapid means to normalize intracranial pressure and can
prevent brain damage. In the U.S. there are approximately 69,000 annual hospital
admissions for hydrocephalus resulting in over 40,000 shunting procedures and
costing over one billion dollars. The excessive costs predominantly arise from
relatively high complication and revision rates as well as costly equipment.
This novel device and technique help avoid complications and associated
This invention relates to a new
type of proximal catheter shunting device and technique for the treatment of
hydrocephalus. Current treatments, although effective in relieving intracranial
pressures, are associated with high failure rates causing morbidity and high
cost. This technology could also be effectively utilized for pressure relief
secondary to trapped fluid in any solid organ.
This novel device can be
implanted in a minimally invasive manner under x-ray guidance, only requiring a
single suture to close and can be performed under local anesthesia. The
catheter would be less prone to obstruction and can easily be
re-accessed without removal in case of failure. In certain embodiments, this
invention would allow for the physiologic restoration of CSF flow rather than
external shunting to the peritoneum. Effective treatment of hydrocephalus with
reduced risk of complications, infection and reduction in associated costs and
surgical time are other major advantages.
