Shunt catheter system

摘要

A shunt catheter system and method of use thereof. The system generally includes an open-ended ventricular catheter with drainage apertures and safety flap valves, a reservoir with inline filter, and a peritoneal catheter. After insertion, for example into the ventricles of the brain, cerebrospinal fluid would pass into the ventricular catheter, through the inline filter in the reservoir, and into the peritoneal catheter, subsequently exiting the shunt catheter system. During insertion of the ventricular catheter, a catheter stylet or wire/string and plug stylet can be positioned therein to occlude the open end. The ventricular catheter may be positioned perpendicular to the peritoneal catheter and can be coupled to one another through the reservoir and inline filter or valve.

1. A shunt catheter system for drainage of a fluid, comprising:
a ventricular catheter having a proximal portion, a distal portion, and a longitudinal extent therebetween, wherein said distal portion of said ventricular catheter terminates at an open distal end such that an interior of said ventricular catheter is in open communication with an external environment of said ventricular catheter through said open distal end; and a plurality of safety flap valves located on said distal portion of said ventricular catheter, said safety flap valves being hingedly connected to a wall of said ventricular catheter and biased against said wall, such that each safety flap valve can hinge into said interior of said ventricular catheter resulting from a force placed on the outside of said safety flap valve, whereby said fluid is configured to follow a path of travel from a ventricular cavity, through said open distal end and through said plurality of safety flap valves, and into said interior of said ventricular catheter.
