Abstract
A system includes a first port comprising a first inlet, a first outlet, a first fluid pathway extending from the first inlet to the first outlet, a second inlet, a second outlet, and a second fluid pathway extending from the second inlet to the second outlet. The system further includes one or more CSF catheters having a first lumen, a first distal opening in fluid communication with the first lumen, a second lumen, and a second distal opening in fluid communication with the second lumen. The one or more CSF catheters are, or are configured to be, operatively coupled with the first implantable device such that the first lumen is in fluid communication with the first fluid pathway and the second lumen is in fluid communication with the second fluid pathway. At least the first distal opening is configured to be placed in the CSF-containing space. The system further includes a second port having a third inlet, a third outlet, and a third fluid pathway extending from the third inlet to the third outlet. The system also includes a port catheter configured to operatively couple the third fluid pathway to the second fluid pathway.
