Abstract

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.

First claim

What is claimed is:

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.

2. A shunt catheter system as in claim 1 , further comprising:
a reservoir having a base and a hemispherical dome connected to a top surface of said base, said hemispherical dome having a bias toward being inflated but capable of being depressed upon a force being applied to said hemispherical dome,
said proximal portion of said ventricular catheter coupled to said reservoir, such that said interior of said ventricular catheter is in fluid communication with an interior of said reservoir;
a peritoneal catheter having a proximal end, a distal end, and a longitudinal extent therebetween, wherein said proximal end of said peritoneal catheter is coupled to said reservoir,
whereby said fluid follows a path of travel through said open distal end and through said plurality of safety flap valves into said interior of said ventricular catheter, through said ventricular catheter and into said reservoir, and into said peritoneal catheter prior to being flushed out.

3. A shunt catheter system as in claim 1 , further comprising:
an inline filter positioned within said interior of said reservoir, said inline filter having a plurality of vertically-oriented apertures positioned along a perimeter of said inline filter, such that said interior of said reservoir is in fluid communication with an interior of said peritoneal catheter through an aperture of said plurality of vertically-oriented apertures, said peritoneal catheter having a diameter that is parallel to a diameter of said aperture.

4. A shunt catheter system as in claim 1 , further comprising:
an occluding component extendable through said longitudinal extent of said ventricular catheter for occluding said open distal end of said distal portion of said ventricular catheter during insertion of said ventricular catheter, said occluding component having a rounded distal end.

5. A shunt catheter system as in claim 4 , further comprising:
said occluding component being a catheter stylet having a proximal end and said rounded distal end,
said catheter stylet including a stopper for preventing said catheter stylet from extending excessively beyond said open distal end of said ventricular catheter, such that said proximal end of said catheter stylet is disposed external to said ventricular catheter and said rounded distal end of said catheter stylet occludes said open distal end of said ventricular catheter.

6. A shunt catheter system as in claim 4 , further comprising:
said occluding component being a wire and plug assembly having a proximal end and a rounded distal plug, said wire and plug assembly including a wire extending proximally from said rounded distal plug,
said wire and plug assembly including a safety clip for preventing said rounded distal plug from being disposed excessively beyond said open distal end of said ventricular catheter, such that said proximal end of said wire and plug assembly is disposed external to said ventricular catheter and said rounded distal plug of said wire and plug assembly occludes said open distal end of said ventricular catheter.

7. A shunt catheter system as in claim 6 , further comprising:
said safety clip having a central aperture disposed therein, said central aperture having a diameter that is substantially equal to an internal diameter of said ventricular catheter.

8. A shunt catheter system as in claim 1 , further comprising:
a plurality of drainage apertures located on said distal portion of said ventricular catheter,
said plurality of drainage apertures providing open communication between said interior of said ventricular catheter and said external environment of said ventricular catheter.
