A microcatheter comprising an elongate flexible tubular body, a tip body and acoupling is disclosed. The elongate flexible tubular body has a proximal end,a distal endand at least one lumen extending axially therethrough. The tip body has aproximal endand a distal end and a lumen extending axially therethrough. The couplingcovers aportion of both the tubular body and tip body and is made from a firstmaterial and asecond material, where the first material is different from the secondmaterial. The firstmaterial is compatible with an outermost layer of the tubular body and anoutermost layerof the tip body, and the second material is configured to form a detachablebond with atleast one of the tubular body and the tip body.
