Abstract
Apparatus and methods are provided for utilizing a combination of ultrasonic energy and an echo contrast agent containing microbubbles, for substantially dissolving blood clots or other vascular obstructions. One embodiment of the present invention utilizes a selected dose of thrombolytic agent in combination with an echo contrast agent, for enhancing the thrombolytic action of a thrombolytic agent and removing a thrombosis from a vascular system in less time than the time required by activity of the selected dose of thrombolytic agent without the ultrasonic radiation of the thrombosis.
