ABSTRACT:
The neuro-microcatheter is especially adapted for use in the small blood vessels of the brain. The neuro-microcatheter comprises a generally tubular body including a proximal portion, a transition portion and a distal portion and having at least one lumen therein extending from a distal end of the tubular body to a proximal end of the tubular body to which a connecting member can be connected. The tubular body has, in the transition portion, an outer diameter which decreases gradually, over at least part of its length, in the direction from the proximal end of the tubular body toward the distal end of the tubular body. Also, the transition portion increases in flexibility in the direction from the proximal end of the tubular body toward the distal end of the tubular body; and the transition portion has a length of between approximately 0.05 centimeter to approximately 1 meter.
