ABSTRACT:
The invention relates to an apparatus and method for imaging and mapping various structures located at a target area within a patient's lumen using conventional IVUS technology. The mapped images are used to accurately determine and control the location of the device within the lumen relative to the target area and/or target site. Once the drug delivery device is properly positioned within the lumen, additional ultrasonic images are generated and used to control the position and depth of penetration of a retractable needle of the device. Needle position can be precisely determined, both in relationship to the device as well as the target site for drug delivery. This allows accurate delivery of drug to the target site and, thus, enhanced treatment capabilities.
