Two-lumen catheter for distal protection in percutaneous coronary and peripherical intervention

Claim 1

A two-lumen catheter for distal protection and removing thrombi in peripheral and percutaneous coronary surgery interventions, said two lumen catheter comprising a tubular body defining a first lumen for allowing a guide wire to pass therethrough and a second lumen for coupling to a sucking assembly, said first lumen having a cross-section smaller than a cross-section of said second lumen, wherein said catheter further comprises an end portion defining a tapering portion integral with said tubular body arranged between the tubular body and a catheter tip integral with said tapering portion and having a bulged outer surface, said tapering portion having one or more holes for communicating with said second lumen and a distal end with an outlet hole for allowing said guide wire to coaxially exit said catheter, said tapering portion being defined by a first substantially rectilinear coupling portion integrally connecting to said tubular body and by a second substantially curved coupling portion integrally connecting to and matching with said bulged outer surface of said catheter tip, wherein said tapering portion has a length substantially equal to a length of said catheter tip, and wherein said bulged surface of the catheter tip defines an ogival shape.
