Abstract: A reperfusion catheter for controlled reperfusion in an occluded artery is disclosed. A tubular perfusion catheter (12) has a proximal a distal end and a lumen defined in between said ends. The catheter (12) has a dilatator (13) which is sized and shaped to move telescopically in its lumen. The tubular perfusion catheter (12) has at least one perfusion port (16) which, in use, allows, antegrade blood flow to enter the lumen of the perfusion catheter (12). The at least one perfusion port (16) extends in the longitudinal direction of the perfusion catheter (12) such that, in use, full or partial withdrawal of the dilatator (13) out of the lumen of the perfusion catheter (12) permits controlled flow of blood through said perfusion port (16) and out of the distal end of the tubular perfusion catheter.
