ABSTRACT:
Probe-like catheter has a small diameter and can be steered to and passed through narrow stenoses. The probe has a balloon at its distal end which is collapsible to a low profile to enable it to be passed through the stenosis. The probe may include a distal tip which can hold a preset curve. The probe is sufficiently rigid to enable the transmission of torque to the distal end to permit steering of the probe by controllably rotating the proximal end of the probe.
In use, a stenosis which cannot be crossed by a more conventional sized dilatation catheter may permit passage of the dilatation probe.
