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.
