US 2025/0205461 A1 · APPARATUS FOR SHUNTING CEREBROSPINAL FLUID

Abstract

Apparatus for shunting cerebrospinal fluid comprising either a sleeved ventricular catheter and/or an artificial dural sac (ADS). The sleeved ventricular catheter comprises an inner catheter and an outer catheter that circumscribes and is spaced apart from at least a portion of the inner catheter to form a gap. The inner catheter comprises a plurality of apertures through which CSF may enter the inner catheter. The ADS comprises a flexible wall defining a volume where CSF accumulates. The ADS is coupled to the ventricular catheter via an ADS catheter and a Y-connector. The ADS is adapted to be placed in an abdomen such that abdominal movement, diaphragmatic movement, or a decrease in intracranial pressure causes CSF to flow from the ADS through the ventricular catheter and into a ventricle in the brain.
