Patent number: 9943675Abstract: A method of treating an occlusion at a treatment site within a patient's vasculature comprises providing an ultrasonic catheter. The ultrasonic catheter has a distal region, a proximal region opposite the distal region, a fluid delivery lumen having at least one opening in the distal region, and an ultrasound radiating member positioned within the distal region. The method further comprises positioning the ultrasonic catheter at the treatment site, such that at least a portion of the distal region is within the occlusion. The ultrasonic catheter further comprises passing a therapeutic compound through the fluid delivery lumen such that the therapeutic compound is delivered to the treatment site. The ultrasonic catheter further comprises emitting ultrasonic energy from the ultrasound radiating member. The emitted ultrasonic energy has an amplitude that is periodically varied between a low amplitude and a high amplitude.Type: GrantFiled: September 4, 2014Date of Patent: April 17, 2018Assignee: EKOS CORPORATIONInventors: George Keilman, Douglas R. Hansmann, Azita Soltani, Richard R. Wilson

Patent number: 9849273Abstract: An ultrasound catheter system and a method for operating an ultrasonic catheter at a treatment site within a patient's vasculature or tissue are disclosed. The ultrasound catheter system comprises a catheter having at least one ultrasonic element and a control system configured to generate power parameters that drive the at least one ultrasonic element to generate ultrasonic energy. The control system is configured to vary at least one of the power parameters and at least one physiological parameter by repeatedly cycling the power parameter and the physiological parameter through two set of values.Type: GrantFiled: April 24, 2012Date of Patent: December 26, 2017Assignee: EKOS CORPORATIONInventors: Azita Soltani, Kim R.

Patent number: 9579494Abstract: An ultrasound catheter with a lumen for fluid delivery and fluid evacuation, and an ultrasound source is used for the treatment of intracerebral or intraventricular hemorrhages. After the catheter is inserted into a blood clot, a lytic drug can be delivered to the blood clot via the lumen while applying ultrasonic energy to the treatment site. As the blood clot is dissolved, the liquefied blood clot can be removed by evacuation through the lumen.Type: GrantFiled: March 13, 2014Date of Patent: February 28, 2017Assignee: Ekos CorporationInventors: Jocelyn Kersten, Curtis Genstler, Raymond M. Wolniewicz, III, Douglas R. Hansmann
