A method for profiling an infusion of a medicament into the wall of an artery involves inserting an intravascular ultrasound device into the artery and advancing it to the location of the infusion. A pullback device withdraws the intravascular ultrasound device from the artery, pausing at predetermined axial sites along the location of the infiltrated medicament to image the infusion profile at each site. A computer then compiles the individual site profiles to produce three dimensional images indicating the extent of infiltration of the medicament into the tissue surrounding the artery.

1. A method for determining the extent of an infiltration of medicament at a location of infusion of the medicament into an arterial wall of a patient comprising the steps of:advancing an intravascular ultrasound device into an artery of the patient to a start position, said start position being distal to said location of infusion; incrementally withdrawing said intravascular ultrasound device in a proximal direction from said start position to at least one other position in the artery; and activating said ultrasound device at each said position in the artery, to create a profile for the infiltration of said medicament into the arterial wall at each said position.
