ABSTRACT:
Steerable catheter devices are provided having a proximal first end portion, an elongate intermediate portion, and a distal flexible second end portion defining a longitudinal axis, and at least one channel having a proximal opening and terminating at an occluded distal end radially offset relative to the central longitudinal axis and positioned within the catheter flexible second end portion substantially straight in a relaxed position and bent when the occluded distal end is under a change in internal fluid pressure. Optionally, the catheter further has a dye injection lumen and a tool receiving passageway extending from the first end portion to the second end portion. The occluded distal end is axially elastically distensible under an internal fluid pressure to deflect (thereby to steer) the catheter second end portion through the tortuous path of a vessel passageway when used percutaneously or working channel of an endoscope or endoscope accessory device.
