Methods and apparatuses for drug delivery to an intravascular occlusion

1. A method for treating an intravascular occlusion, comprising:

• delivering a catheter having a proximal end and a distal end and a lumen extending therethrough into a blood vessel to a site near the intravascular occlusion, the catheter having an occlusive device on the distal end;
  
  actuating the occlusive device at a location distal to the intravascular occlusion to at least partially occlude blood flow through the vessel; and
  
  delivering a drug-containing fluid through the lumen of the catheter and out through at least one hole in a proximal face of the occlusive device such that the fluid is delivered in a distal to proximal direction.
