ABSTRACT:
An interventional catheter assembly comprising a catheter for insertion and guidance to a target site in a body lumen or a cavity and an operating head mounted in proximity to a distal end of the catheter and comprising a system for removing obstructive material from the target site is provided. In certain embodiments, the catheter assembly includes at least one aspiration port located proximal to the operating head that communicates with a first sealed lumen for withdrawing fluids and obstructive material from the target site, together with at least one liquid infusion port penetrating the catheter and located proximal to the at least one aspiration port that communicates with a second sealed lumen for supplying fluid to a location in proximity to the target site.
