Shunt
First Claim
1. A cerebral spinal fluid (CSF) draining shunt, comprising:
- a CSF space catheter configured to (i) be inserted into a CSF space of a patient and (ii) to receive CSF from the CSF of the patient;
a body cavity catheter configured to (i) be inserted into a body cavity of the patient, and (ii) to drain the CSF received by said CSF space catheter into the body cavity;
an implantable master control unit configured to be implanted into the patient in a biocompatible location, said master control unit interconnecting said CSF space catheter and said body cavity catheter, said master control unity having a regulator for selectively draining an excess of said CSF from said CSF space catheter to said body cavity catheter; and
, an access port disposed in at least one of said CSF space catheter and said body cavity catheter, such that when said access port is disposed in said CSF space catheter access is provided to said CSF space and when said access port is disposed in said body cavity catheter access is provided to said body cavity.

Abstract
A shunt for draining cerebral spinal fluid from the brain is provided. In an embodiment, the shunt includes a master control unit that is located in the abdomen, which interconnects a ventricular catheter and a second catheter, typically located in the peritoneal cavity. In a specific embodiment, the master control unit includes a variety of ‘smart’ features including at least one access port to allow the injection of solutions for the prevention or removal of blockages in the catheter, and/or antibiotics. The access port can have other uses, such as allowing a point of access for physical navigation of a catheter or the like within the shunt, thereby providing another option for breaking-up blockages, and/or allowing an access point for repairing the shunt'"'"'s components. Additionally, the master control unit includes a diagnostic unit that transmits, either wirelessly or through a wired connection via the access port, diagnostic information about the status of the patient and/or the shunt.
