Balloon catheter with deformable fluid delivery conduit

摘要

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.

主权项

1. A method of thermally treating tissue, comprising:
positioning an expandable element of a medical device adjacent to the tissue, the medical device includes a guide wire lumen at least partially disposed within the elongate body and at least partially disposed within the interior of the expandable element; delivering a fluid into an interior of the expandable element with a fluid delivery conduit to expand the expandable element, the fluid delivery conduit being in a first geometric configuration, the fluid delivery conduit including a deflectable segment defining a proximal end and a distal end with the proximal end being slidably and rotatably coupled to the guide wire lumen and the distal end being immovably fixed to the guide wire lumen; thermally treating a first region of the tissue with the expandable element; transitioning the fluid delivery conduit from the first geometric configuration into a second geometric configuration; and thermally treating a second region of the tissue with the expandable element.
