Abstract
A medical device, including an elongate body having a proximal portion and a distal portion; a shaft at least partially disposed within the elongate body; an expandable element at the distal portion of the elongate body; and a fluid delivery conduit defining a deflectable segment movably coupled to the shaft, the deflectable segment being transitionable from a substantially linear configuration to a substantially curvilinear configuration.
Claims15
A medical device, comprising:
- an elongate body having a proximal portion and a distal portion;
- a shaft at least partially disposed within the elongate body;
- an expandable element at the distal portion of the elongate body;
- and
- a fluid delivery conduit defining a deflectable segment defining a proximal end and a distal end with the proximal end being slidably and rotatably coupled to the shaft and the distal end being immovably fixed to the shaft, the deflectable segment being transitionable from a linear configuration to a curvilinear configuration.
