Abstract
An intraventricular access device for infusion of drugs and aspiration of cerebrospinal fluid (CSF). The device includes a container configured to couple to an aspiration lumen through which CSF may be aspirated or through which drugs may be injected. The container is further configured to couple to an infusion lumen and to a drug pump via a catheter. The container thus forms a pathway connectable to the catheter through which a drug from the drug pump may be infused to flow through the infusion lumen into the CSF. The container includes a volume that is accessible by an aspiration needle, for example through a material that reseals upon extraction of the needle. Moreover, the container is configured to prevent cross contamination between a first fluid in the aspiration lumen and a second fluid in the infusion lumen.
