ABSTRACT:
The invention is directed to an introducer which is formed of a relatively rigid tubular member having an inner lumen and an elongated slot in the distal portion of the introducer. The introducer is particularly suitable for introducing an elongated channel forming device having radially extending arms for limiting the depth of penetration into a guiding or delivery catheter. By pulling the channel forming member into the inner lumen of the introducer, the radially extending arms are bent or folded forwardly into the inner lumen and they remain in this position until they extend out the distal end of the guiding or delivery catheter.
