A reperfusion catheter for controlled reperfusion in an occluded artery, said catheter comprising: • a tubular perfusion catheter having a proximal end and a distal end and a lumen defined in between said proximal and distal ends (24, 25), • a dilatator which is sized and shaped to move telescopically in the lumen of said perfusion catheter, wherein the tubular perfusion catheter has at least one perfusion port which is formed in the shell of the tubular perfusion catheter and which, in use, allows, antegrade blood flow to enter the lumen of the perfusion catheter, characterized in that: the at least one perfusion port is fully blocked by the dilatator when said dilatator is fully inserted in the lumen of the perfusion catheter, wherein said at least one perfusion port extends in the longitudinal direction of the perfusion catheter such that, in use, full or partial withdrawal of the dilatator out of the lumen of the perfusion catheter permits controlled flow of blood through said perfusion port and out of the distal end of the tubular perfusion catheter. • a tubular perfusion catheter having a proximal end and a distal end and a lumen defined in between said proximal and distal ends (24, 25), • a dilatator which is sized and shaped to move telescopically in the lumen of said perfusion catheter, wherein the tubular perfusion catheter has at least one perfusion port which is formed in the shell of the tubular perfusion catheter and which, in use, allows, antegrade blood flow to enter the lumen of the perfusion catheter, characterized in that: the at least one perfusion port is fully blocked by the dilatator when said dilatator is fully inserted in the lumen of the perfusion catheter, wherein said at least one perfusion port extends in the longitudinal direction of the perfusion catheter such that, in use, full or partial withdrawal of the dilatator out of the lumen of the perfusion catheter permits controlled flow of blood through said perfusion port and out of the distal end of the tubular perfusion catheter. the tubular perfusion catheter has at least one perfusion port which is formed in the shell of the tubular perfusion catheter and which, in use, allows, antegrade blood flow to enter the lumen of the perfusion catheter, characterized in that: the at least one perfusion port is fully blocked by the dilatator when said dilatator is fully inserted in the lumen of the perfusion catheter, wherein said at least one perfusion port extends in the longitudinal direction of the perfusion catheter such that, in use, full or partial withdrawal of the dilatator out of the lumen of the perfusion catheter permits controlled flow of blood through said perfusion port and out of the distal end of the tubular perfusion catheter. the at least one perfusion port is fully blocked by the dilatator when said dilatator is fully inserted in the lumen of the perfusion catheter, wherein said at least one perfusion port extends in the longitudinal direction of the perfusion catheter such that, in use, full or partial withdrawal of the dilatator out of the lumen of the perfusion catheter permits controlled flow of blood through said perfusion port and out of the distal end of the tubular perfusion catheter.
