摘要:
A dilation catheter system includes a body, a guidewire, and a dilation catheter having an elongate shaft. The dilation catheter system may include a locking mechanism to prevent the guidewire from moving relative to the elongate shaft or to lock the guidewire to the dilation catheter to form a fixed wire unit. The dilation catheter system may include a stabilizing tube extending from an actuator, to provide rigidity to the guidewire. The dilation catheter may include a grip element having a plurality of grip features disposed thereon. The dilation catheter may include a cap biased toward a first longitudinal position and movable to a second longitudinal position. A guide catheter secured to the cap is prevented from changing angular orientation in the first longitudinal position and is free to change angular orientation in the second longitudinal position.
