Abstract
A microcatheter for delivering embolic agent to a vascular site is provided. The microcatheter has a biocompatible or biocompatible and biodegradable tip which can be detachably engaged to the microcatheter body by a thermoplastic sleeve. Once the embolic agent is delivered to the desired vascular site, the tip of the microcatheter is often entrapped within the mass of the liquid embolic fluid. Using the microcatheter, the clinician can retract the microcatheter at a predetermined retraction force thereby disengaging the tip from the microcatheter body allowing for easier removal of the microcatheter.
