摘要：
A medical instrument includes an expandable balloon, an intra-balloon deflection assembly, and one or more puller wires. The expandable balloon is coupled to a distal end of a shaft for insertion into a body of a patient. The intra-balloon deflection assembly is also coupled to the distal end of the shaft, and includes a distal section of the shaft which extends partially through the expandable balloon and includes (i) an elastic element coupled to a proximal side of the expandable balloon and configured to be bent relative to a longitudinal axis of the shaft, and (ii) a rigid element coupled to a distal side of the expandable balloon. The one or more puller wires are coupled to the rigid element and are configured to bend the elastic element, thereby deflecting the expandable balloon.
