SURGICAL DRAIN FOR SHUNTING FLUID

摘要

Hydrocephalus shunt which includes a subcutaneous pump, devoid of rigid or metallic parts, characterized by a one-way slit valve which may be distorted and opened by digital pressure in the plane of the slit to break up and dislodge any particulate matter which may be clogging the valve. The body of the pump includes means for positioning said pump, following subcutaneously implanting thereof, within the body tissue such that the slit is maintained in a position generally normal to the surface of the cranium. Said means of said pump may include projections which may be sewed to soft tissue beneath the scalp or may include a pump of predetermined cross section such as of oval cross-sectional configuration.
