Detection and clearing of occlusions in catheters
First Claim
1. A system comprising:
- a catheter in fluid communication with a fluid of a patient'"'"'s body;
a shunt in fluid communication with the catheter;
a detection circuit comprising one or more wires in electrical communication with the fluid, detecting a change in one or more electrical properties of the fluid to detect an occlusion in the catheter; and
a transmission circuit, comprising one or more other wires in electrical communication with the fluid, providing an electromagnetic signal to the fluid to remove the occlusion in the catheter;
wherein;
the catheter comprises one or more drain holes and an inner lumen;
the one or more wires of the detection circuit, the transmission circuit, or both are disposed at least partially in a sidewall of the catheter and in electrical communication with the fluid;
the catheter further comprises a wire lumen with one or more access ports; and
a portion of the one or more wires of the transmission circuit, detection circuit, or both are housed in the wire lumen in electrical communication with the fluid.

Abstract
A catheter system with integral sensing and clearing of occlusions is described. The system can include a catheter in fluid communication with a shunt for transporting a bodily fluid within, or out of, a patient'"'"'s body. The catheter and/or the shunt can include one or more detection wires and one or more transmission wires. The detection wires can be in electrical communication with the fluid and can enable the detection of changes in electrical properties of the fluid indicating an occlusion, or other anomaly, in the catheter. The transmission wires can be in electrical communication with the fluid and can enable the application of electromagnetic energy to the occlusion to facilitate its removal. The detection wires and the transmission wires can be the same or different wires. The system can include a probe that can be externally connected to the wires to provide detection and or transmission signals.
