Abstract
A catheter comprising an inner tube having a distal end, a first lumen and a first delivery opening communicating with the first lumen for delivery of fluid to a patient and a second outer tube having a distal end, a second lumen and a first withdrawal opening communicating with the second lumen to withdraw fluid from the patient. The inner tube is positioned within the outer tube and the inner and outer tubes are relatively movable between a first and second position. In the first position, the distal end of the inner tube is spaced a first distance from the distal end of the outer tube to enable withdrawal of fluid and in the second position the withdrawal opening is blocked to prevent withdrawal of fluid from the patient.
