A balloon catheter having an elongated catheter shaft defining a fluid drainage lumen and a balloon inflation lumen. The balloon catheter includes a fluid drainage port disposed about the distal end of the catheter shaft in fluid communication with the fluid drainage lumen, and a balloon inflation port disposed about the distal end of the catheter shaft in fluid communication with the balloon inflation lumen. A balloon portion is disposed about the distal end of the catheter shaft in fluid communication with the balloon inflation port. A release device is disposed in fluid communication with the balloon portion and the fluid drainage lumen, and includes an activating member. A tether is attached to the activating member of the release device. Tension applied to the tether activates the release device, enabling fluid flow from the balloon portion into the fluid drainage lumen and out of the body. |
