Treatment of vascular occlusions using ultrasonic energy and microbubbles
First Claim
1. A method of treating a vascular occlusion located at a treatment site within a patient'"'"'s vasculature, the method comprising:
- positioning an ultrasound catheter at the treatment site;
delivering a microbubble therapeutic compound from the ultrasound catheter to the vascular occlusion during a first treatment phase; and
pausing the delivery of the microbubble therapeutic compound and delivering ultrasonic energy from the ultrasound catheter to the vascular occlusion during a second treatment phase while the delivery of microbubble therapeutic compound remains paused.

Abstract
In one embodiment of the present invention, a method of treating a vascular occlusion located at a treatment site within a patient'"'"'s vasculature comprises positioning an ultrasound catheter at the treatment site. The method further comprises delivering a microbubble therapeutic compound from the ultrasound catheter to the vascular occlusion during a first treatment phase. The method further comprises pausing the delivery of the microbubble therapeutic compound and delivering ultrasonic energy from the ultrasound catheter to the vascular occlusion during a second treatment phase while the delivery of microbubble therapeutic compound remains paused.

13. A method of treating a vascular occlusion located at a treatment site within a patient'"'"'s vasculature, the method comprising:
-
passing an ultrasound catheter through the patient'"'"'s vasculature to the treatment site, wherein the ultrasound catheter includes at least one fluid delivery port; positioning the ultrasound catheter at the treatment site such that the at least one fluid delivery port is positioned within the occlusion; infusing a microbubble therapeutic compound from the ultrasound catheter into an internal portion of the occlusion; pausing delivery of the microbubble therapeutic compound from the ultrasound catheter after a first quantity has been infused into the occlusion; delivering ultrasonic energy from the ultrasound catheter into the infused microbubble therapeutic compound; repositioning the ultrasound catheter at the treatment site; and infusing a second quantity of microbubble therapeutic compound from the ultrasound catheter to the treatment site after the ultrasonic energy is delivered to the treatment site. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. An ultrasound catheter system comprising:
-
an elongate tubular body having an ultrasound radiating member and a fluid delivery lumen positioned therein; a fluid reservoir that is hydraulically coupled to a proximal portion of the fluid delivery lumen, the fluid delivery reservoir containing a microbubble therapeutic compound; an infusion pump configured to pump the microbubble therapeutic compound from the fluid reservoir into the fluid delivery lumen; and control circuitry configured to send electrical activation power to the infusion pump and to the ultrasound radiating member, wherein the control circuitry is configured such that the infusion pump and the ultrasound radiating member are not activated simultaneously. - View Dependent Claims (22, 23, 24, 25)
