Abstract
A cryoablation catheter assembly includes a catheter that defines at least one coolant outtake region and receives a rotatable guide tube and a coolant transfer tube. The coolant transfer tube receives and transfers coolant from a coolant source to a distal end of the coolant transfer tube. An expansion element is coupled to a distal portion of the catheter and defines an inner expansion-element space. The inner expansion-element space is in fluid communication with the at least one coolant outtake region and the distal end of the coolant transfer tube. A distal end of the expansion element couples to the guide tube. A rotation system is coupleable to, or coupled to, a proximal end of the guide tube and rotates the distal end of the expansion element relative to the proximal end of the expansion element by rotating the guide tube relative to the catheter.
