Patent number: 10575819Abstract: A rotational intravascular ultrasound probe for insertion into a vasculature and a method of manufacturing the same. The rotational intravascular ultrasound probe comprises an elongate catheter having a flexible body and an elongate transducer shaft disposed within the flexible body. The transducer shaft comprises a proximal end portion, a distal end portion, a drive shaft extending from the proximal end portion to the distal end portion, an ultrasonic transducer disposed near the distal end portion for obtaining a circumferential image through rotation, and a transducer housing molded to the drive shaft and the ultrasonic transducer.Type: GrantFiled: June 17, 2013Date of Patent: March 3, 2020Assignee: PHILIPS IMAGE GUIDED THERAPY CORPORATIONInventors: Stephen Charles Davies, Norman Hugh Hossack, Peter Howard Smith

Patent number: 10052082Abstract: A method and system is provided for using backscattered data and known parameters to characterize vascular tissue. Specifically, methods and devices for identifying information about the imaging element used to gather the backscattered data are provided in order to permit an operation console having a plurality of Virtual Histology classification trees to select the appropriate VH classification tree for analyzing data gathered using that imaging element. In order to select the appropriate VH database for analyzing data from a specific imaging catheter, it is advantageous to know information regarding the function and performance of the catheter, such as the operating frequency of the catheter and whether it is a rotational or phased-array catheter. The present invention provides a device and method for storing this information on the imaging catheter and communicating the information to the operation console.Type: GrantFiled: August 7, 2015Date of Patent: August 21, 2018Assignee: Volcano CorporationInventors: Norman Hugh Hossack, Stephen Charles Davies, Donald Mamayek, Richard Scott Huennekens, Stephen M. Fry, Eric Vaughn Mott, Peter Smith, Scott Tennant Brownlie, Jon David Klingensmith, Richard Chester Klosinski, Jr., Edward Anthony Oliver, Masood Ahmed, Gerald Lea Litzza

Patent number: 9585634Abstract: An ultrasound catheter assembly having a rotatable transducer assembly is disclosed. The ultrasound catheter assembly includes an elongate flexible shaft having a lumen and a proximal end and a distal end. The catheter assembly further includes a drive member that engages the transducer assembly at a distal end of the catheter. Rotation of the drive member in a first direction causes the transducer assembly to rotate in an oscillatory fashion in a second direction.Type: GrantFiled: October 29, 2012Date of Patent: March 7, 2017Assignee: Volcano CorporationInventors: Stephen Charles Davies, Norman Hugh Hossack

Patent number: 8932226Abstract: An ultrasound catheter is described herein for insertion into a cavity such as a blood vessel to facilitate imaging within a vasculature. The catheter comprises an elongate flexible shaft, a capacitive microfabricated ultrasonic transducer, and a sonic reflector. The elongate flexible shaft has a proximate end and a distal end. A capacitive microfabricated ultrasonic transducer (cMUT) is mounted to the shaft near the distal end. The reflector is positioned such that a reflective surface redirects ultrasonic waves to and from the transducer. In other embodiments, the catheter comprises a plurality of cMUT elements and operates without the use of reflectors. In further embodiments, integrated circuitry is incorporated into the design.Type: GrantFiled: July 31, 2012Date of Patent: January 13, 2015Assignee: Volcano CorporationInventors: Norman Hugh Hossack, Blair Walker, Stephen Charles Davies, Donald Stanley Mamayek, John F.

Patent number: 8840560Abstract: A hand-operated intracardiac echocardiography (ICE) catheter is described for flexed and rotational steering is described for improved catheter operation, control and less trauma on patients. The disclosed catheter assembly includes ultrasound transducers mounted upon a rotatable tip mounted on a distal end of a flexible elongate shaft. A set of steering lines are controlled by a steering actuator to articulate bidirectionally a distal segment of the catheter. Another steering actuator controls rotation of a torque member that, in turn is coupled to the rotatable tip. A user, through the steering actuators, affects repositioning the ultrasonic transducers by repositioning exposed control surfaces of the steering actuators lengthwise along the housing of the handle.Type: GrantFiled: April 4, 2007Date of Patent: September 23, 2014Assignee: Volcano CorporationInventors: Norman Hugh Hossack, Richard Scott Huennekens, Rovil Rae Pascual Arcia, Ernest W.
