Abstract
Catheters for removing interstitial fluid from a cerebral edema that comprises an edema drainage section terminating in a proximal tip linked to a fluid transport section terminating in a distal tip are disclosed. The edema drainage section comprises an outer wall, an inner drainage tube and an intermediate solute compartment that comprises a solute. Methods of removing fluid from a cerebral edema of an individual are disclosed, and comprise the steps of inserting the edema drainage section of the catheter into communication with the fluid of the cerebral edema and inserting the fluid transport section of the catheter into a fluid receptacle or the individual's peritoneal cavity. The fluid is drawn into the edema drainage section and emerges from the distal tip of the fluid transport section of the catheter.
