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. ## Claims ### Claim 1 A catheter comprising: an elongated catheter shaft defining a first lumen and a second lumen, the elongated catheter shaft having a proximal end and a distal end; a first port fluidically coupling the first lumen to the second lumen; a balloon coupled to an exterior of the elongated catheter shaft; a second port fluidically coupling the second lumen to the balloon, wherein the first port is positioned distal to the second port such that there is no fluidic connection between the first lumen and the second lumen proximal to the first port; an activating member moveable between a first position and a second position, wherein the activating member prevents fluid from flowing from the balloon to the first port in the first position, and wherein the activating member allows fluid to flow from the balloon to the first port in the second position; and a tether having a proximal end and a distal end, wherein the distal end of the tether is coupled to the activating member, and wherein a movement of the proximal end of the tether in a proximal direction causes the activating member to transition from the first position to the second position. ### Claim 2 (depends on 1) The catheter of claim 1, wherein an elasticity of the elongated catheter shaft is greater than an elasticity of the tether. ### Claim 3 (depends on 1) The catheter of claim 1, wherein the proximal end of the tether is attached proximal to the distal end of the elongated catheter shaft. ### Claim 4 (depends on 1) The catheter of claim 1, wherein the tether is positioned at least partially within the second lumen. ### Claim 5 (depends on 1) The catheter of claim 1, further comprising: a balloon inflation connector in fluid communication with the second lumen. ### Claim 6 (depends on 5) The catheter of claim 5, wherein the proximal end of the tether is affixed to the second lumen about the balloon inflation connector. ### Claim 7 (depends on 1) The catheter of claim 1, wherein a diameter of the tether is less than a diameter of the second lumen. ### Claim 8 (depends on 1) The catheter of claim 1, wherein the activating member comprises a slidable plug disposed within the second lumen. ### Claim 9 (depends on 8) The catheter of claim 8, wherein the slidable plug seals the second lumen. ### Claim 10 (depends on 8) The catheter of claim 8, wherein the slidable plug is positioned between the first port and the second port in the first position, and wherein the slidable plug is positioned proximal to the second port in the second position. ### Claim 11 (depends on 1) The catheter of claim 1, wherein the activating member comprises a flexible flap, wherein the flexible flap covers the first port in the first position, and wherein the flexible flap does not cover the first port in the second position. ### Claim 12 (depends on 11) The catheter of claim 11, wherein the tether is coupled to a distal end of the flexible flap. ### Claim 13 (depends on 1) The catheter of claim 1, wherein the activating member comprises a gate valve, wherein the gate valve covers the first port in the first position, and wherein the gate valve does not cover the first port in the second position. ### Claim 14 (depends on 13) The catheter of claim 13, wherein the tether is coupled to a proximal end of the gate valve. ### Claim 15 (depends on 1) The catheter of claim 1, wherein the first port comprises a single port that provides an exclusive fluidic coupling between the first lumen and the second lumen. ### Claim 16 (depends on 1) The catheter of claim 1, wherein the second port comprises a single port that provides an exclusive fluidic coupling between the second lumen and the balloon.
