Abstract
In some embodiments, a device may include an intraventricular access device and an infusion device. The intraventricular access device may include more than one catheter and a container. In some embodiments, the catheter may include an aspiration lumen and an infusion lumen. A distal end of the intraventricular portion of the catheter may be positionable, during use, in a subject's brain fluid. In some embodiments, the container may be coupled to a proximal end of the aspiration lumen. The proximal end of the aspiration lumen may be in fluid communication with the container. In some embodiments, the container may include a barrier positioned between a proximal opening of the aspiration lumen and at least a portion of the infusion lumen adjacent to and/or associated with the container. The barrier may inhibit penetration of a surgical instrument.
