Abstract
A cryoballoon deflation assembly for an intravascular catheter system for use during a cryoablation procedure includes a first deflation initiator and a first deflation initiator inhibitor. The first deflation initiator is configured to automatically activate a vacuum pump to deflate a cryoballoon upon completion of a stage of the cryoablation procedure. The first deflation initiator inhibitor is manually changeable to between an activated and deactivated state. When in the activated state, the first deflation initiator inhibitor is configured to inactivate the first deflation initiator. The cryoballoon deflation assembly can further include a second deflation initiator. The second deflation initiator is manually changeable between an activated and deactivated state. When in the activated state, the second deflation initiator is triggered to activate the vacuum pump to deflate the cryoballoon.
