Abstract
A catheter and a method for using the catheter for site specific delivery of agents to or collecting agents from biological spaces. The catheter includes an inner shaft longitudinally movable within an outer shaft, each shaft having at least one balloon and at least one lumen formed therein. The catheter prevents leaking through a biological membrane by sealing the catheter tip passageway through the biological membrane with inflatable balloons on either side of the biological membrane. Further, the inflated balloons secure the position of the catheter relative to the biological membrane and the biological space targeted for therapy or diagnosis.
