Abstract
A method and device for improving blood circulation to an area of interest within a patient' heart is described. The method comprises inserting a guidable elongated flexible ultrasound device into a patient's vasculature, applying ultrasonic energy to an area in need of improved circulation, and injecting materials such as angiogenic materials or contrasting agents into the area of interest. The device, suitable for performing the method, comprises an elongated tubular body, a distal head of the elongated tubular body for introducing ultrasonic energy to an area of interest, and a needle to deliver materials to an area of interest.
