Abstract

The invention relates to a dual catheter arrangement for reperfusion of an ischemic tissue region via a coronary vessel, comprising a primary balloon catheter having a lumen for inflation and deflation of a primary balloon disposed at a distal region of the primary balloon catheter, and at least two separate lumens both extending throughout the primary balloon catheter and open at a distal end of the primary balloon catheter, and a secondary balloon catheter having a lumen for inflation and deflation of a secondary balloon disposed at a distal region of the secondary balloon catheter and an irrigation lumen opening at a distal end of the secondary balloon catheter, which is arranged slidable within one of the lumens of the primary balloon catheter to achieve a working position in which the secondary balloon catheter continues completely through the lumen of the primary balloon catheter and extends distally beyond the primary balloon catheter. Further a system for reperfusion of an ischemic tissue region via a coronary vessel is described comprising the dual catheter arrangement.
