A method, technique and system is disclosed for the delivery of therapeutic agents and/or into the bulk brain tissues and other parts, tissues and organs of the body, including vasculature.

Similarly, the method, technique system may be utilized to remove fluids or other medium from the brain, tissues, and organs to minimize the effects of escaped air or negative pressure.
A catheter device for transferring at least one medium with a subject, wherein said catheter having a distal end and a proximal end, said device comprising:
