SYSTEM AND METHOD FOR ULTRASONIC IMAGING AND ULTRASONIC IRRADIATION OF MICRO-BUBBLES

摘要

PROBLEM TO BE SOLVED: To provide a system and method for ultrasonic imaging and ultrasonic irradiation of micro-bubbles.SOLUTION: A catheter system is provided including an elongate tubular member having a proximal end portion, a distal end portion, and a lumen extending through at least a portion of the entire length of the elongate tubular member. The distal end portion of the elongate member is dimensioned and adapted to advance to or in proximity to a treatment site of a subject. A microbubble device is in fluid communication with the lumen. The microbubble device includes at least one input port for receiving a flow of material into the device and an output port configured to output micro-bubbles from the microbubble device. A second tubular member is in fluid communication with one of the at least one input port. A pressure fitting arrangement is adapted to maintain a seal between the second tubular member and the input port.
