Abstract
A drainage system for draining bile is provided. The drainage system includes an elongated drainage catheter with distal segment and a proximal segment. The catheter includes a first lumen which extends longitudinally through at least a portion of the distal catheter segment and longitudinally through the entire length of the proximal segment. The catheter also includes a second lumen which extends longitudinally solely through at least a portion of the proximal catheter segment. The system includes a drainage bag adapted for connection to the proximal segment to the drainage catheter. A one-way valve is associated with a drainage bag to allow bile to enter into the bag through the second lumen and to exit from the bag into the first lumen.
