Abstract: A microcatheter system is disclosed which may include a microcatheter, one or more microcatheter extensions, and/or a microcatheter hub. In an embodiment, the microcatheter has a plurality of zones where the outside diameter of each zone from the distal to the proximal end has an outside diameter that is the same as or greater than the previous zone while the inside diameter is constant throughout the microcatheter length. In a further embodiment, a unique joining mechanism is employed for coupling a microcatheter to a microcatheter extension or to a microcatheter hub. In a further embodiment, the microcatheter has at least one perforation along a sidewall of the microcatheter.

Abstract: A microcatheter system is disclosed which includes a microcatheter body and a microcatheter extension and/or a microcatheter hub. The microcatheter body includes a plurality of distal zones and a proximal zone. The outside diameter of each of the distal zones is progressively greater than an immediately adjacent and more distal zone. The outside diameter of the proximal zone has an outer diameter at a distal end thereof that is at least as great as the outer diameter of any zone of the plurality of distal zones and increases from the distal end to a proximal end of the distal zone. The inside diameter is constant throughout the microcatheter system. An internal connection assembly comprising a probe and a receptacle join adjacent parts of the microcatheter system.
