An apparatus to increase blood flow through an obstructed blood vessel of a vascular system, the apparatus comprising: a delivery catheter (232) having proximal and distal catheter (238, 240) separated by a hollow light catheter (242) and defining a longitudinal axis (236), the distal end of the catheter (240) adapted for placement within the blood vessel (234) adjacent to an obstruction (244) being a guide (124) wire having proximal and distal guide (128) longitudinally separated by a body of the guide (130) wire wire, the guide wire adapted for selective insertion through the catheter lumen (242) being and an expandable member (100) having a proximal end (104) fixed to the guide (124) wire adjacent the distal end of the guidewire (128), to push or drag the expandable member (100) through the vascular system, being the expandable member (100) selectively movable between a first folded state and a second expanded state, and adapted for passage through the catheter lumen (242) in the folded state and positioning, in the expanded state adjacent the obstruction (244), including the expandable member (100): a proximal end member (104) a distal end member (106), longitudinally spaced from the proximal end of the member (104) a body of the tubular member (108) extending between the proximal and distal ends of the member (104, 106) wherein at least one of the proximal and distal ends of the member (104, 106) closed the body of the tubular member (108) made of a first mesh (110) having a plurality of first gaps (112) being defined by a plurality of first strands (114) and being closed one of the proximal and distal ends of the member (104, 106) made of a second mesh (116) having a plurality of second gaps (118) being the self-expanding expandable member (100) and being constrained in the folded state by the delivery catheter to self-expand to the expanded state at the time of release of light (242) of the delivery catheter (232), at least one of the plurality of first stran
