Patent ID: 7470248

Claim:
A shunt apparatus comprising: a conduit having a first end and a second end, the conduit defining a lumen; a first occlusion assembly coupled to the conduit, the first occlusion assembly having a first balloon disposed in proximity to the first end of the conduit and a first occlusion fluid conduit in fluid communication with the first balloon, the first occlusion fluid conduit having a first visual characteristic; and a second occlusion assembly coupled to the conduit, the second occlusion assembly having a second balloon disposed at the second end of the conduit and a second occlusion fluid conduit in fluid communication with the second balloon, the second occlusion fluid conduit having a second visual characteristic distinct from the first visual characteristic, wherein the first occlusion fluid conduit comprises an occlusion fluid conduit balloon and a sleeve configured to cover the occlusion fluid conduit balloon, the sleeve having a visual sleeve characteristic distinct from the first visual characteristic of the first occlusion fluid conduit, wherein occlusion fluid conduit balloon comprises a balloon color distinct from a sleeve color of the sleeve, the balloon color of the occlusion fluid conduit balloon and the sleeve color of the sleeve configured to optically combine to produce an indication color, distinct from the balloon color and the sleeve color.
