Patent number: 9474506Abstract: An intravascular ultrasound catheter system is provided and enables a simplified, economical technique for ultrasound visualization of a blood vessel. The catheter may include a park ablation system for crossing chronic total occlusions and severe stenoses. The catheter is advanceable and is oriented entirely under manual control of the clinician and the application of radiofrequency energy for spark erosion of the stenosis also is controlled manually by the clinician. The system enables the clinician to observe an ultrasound image sufficiently to determine where to orient the ablation electrode so as to reduce the risk of dissection or perforation of the blood vessel. The ultrasound image is generated in response to manual rotation of the catheter and the ablation spark is generated only when the physician is satisfied as to the orientation of the electrode within the vessel.Type: GrantFiled: July 3, 2013Date of Patent: October 25, 2016Assignee: Volcano CorporationInventors: Paul A. Magnin, Edward I. McNamara, Russell W. Bowden, Rodney J. Solomon

Publication number: 20140180068Abstract: The present invention generally relates to methods, devices and systems for determining the rotational orientation of a device. The invention can involve providing a device comprising a plurality of markers, wherein each marker within the plurality of markers differs from an adjacent marker by size, shape, and/or position on the device. The invention can also involve inserting the device into a vessel and imaging the device to capture an image of the device in an imaging plane. The invention can further involve processing the captured image to determine an orientation of the device relative to the imaging plane based on the markers.Type: ApplicationFiled: December 19, 2013Publication date: June 26, 2014Applicant: VOLCANO CORPORATIONInventors: Jason Spencer, Russell W.
