Low profile shunt system

A shunt system for implantation in the body, comprising:

• a body having an upper and lower surface and a distal and proximal end, the body including a central cavity opening through the upper surface at a first and second port, a proximal fluid flow channel extending through the proximal end of the body and opening at a third port on the upper surface, and a distal fluid flow channel extending through the distal end of the body opening at a fourth port on the upper surface;
• a resilient dome comprised of a self-sealing material attached to and extending over the upper surface of the body, a first portion of the resilient dome extending over the first and third ports on the upper surface defining a first chamber wherein the first portion of the resilient dome upon flexing cooperates with the third port to occlude the third port and wherein a second portion of the resilient dome extends over the second and fourth ports on the upper surface defining a second chamber wherein the second portion of the resilient dome cooperates upon flexing with the fourth port to occlude the fourth port;
• a diaphragm valve means positioned within the central cavity for cooperating with the first port to open or close the first port to fluid flow between the central cavity and first chamber;
• a needle guard means within the central cavity for protecting the diaphragm valve means from puncture when a needle is inserted through the resilient dome into the first chamber;
• tubing means integrally connected to the body at the proximal end in fluid flow communication with the proximal fluid flow channel;
• and
• a distal connector means for connecting to a drainage catheter, integrally attached to the distal end of the body in fluid flow communication with the distal fluid flow channel.
