Abstract: An irrigation balloon catheter includes one or more inner balloons inside of an irrigation balloon. The inner balloon(s) can be compliant with a volume that is dynamically adjustable for rapid inflation, rapid deflation, complete deflation, and/or irrigation flow adjustment. An inflator tool can be configured to inflate or deflate the inner balloon to adjust flow from the outer, irrigation balloon to affect temperature at electrodes of the irrigation balloon.

Abstract: A balloon catheter has a central tube that is configured to both structurally support and inflate a balloon membrane. The central tube has a lumen and sidewall inflation ports that provide a path for inflating the balloon. The lumen of the central tube is obstructed by a distal end piece, nose piece, or other structure to prevent fluid from exiting a distal end of the central tube. The central tube is configured such that, during inflation, inflation media is allowed to pass through an elongated shaft of the catheter, into a proximal open end of the central tube, and through the inflation ports into the balloon. The central tube can slide longitudinally in relation to the shaft to longitudinally elongate and/or truncate the balloon.

Abstract: Shown and described is electrophysiology catheter end effector having a balloon with three expandable membranes attached to each other such that wiring (for the electrodes or other sensors on the membrane surfaces) no longer extend from inside the first membrane yet at the same time is captured between the first membrane and a second membrane.
