Patent number: 9585635Abstract: The present disclosure provides a transducer shaping chamber for shaping ultrasound transducers. The transducer shaping chamber includes a transducer coupon carrier having one or more slots. The one or more slots each are geometrically shaped to hold a transducer coupon having a plurality of ultrasonic transducers formed thereon. The transducer shaping chamber includes a first plate disposed over a first side of the transducer coupon carrier. The transducer shaping chamber includes a second plate disposed over a second side of the transducer coupon carrier. The second side is opposite the first side. The transducer shaping chamber is configured to move the first plate and the second plate toward each other so as to push against the transducer coupon carrier from the first and second sides, respectively, until the transducer coupon carrier has been sealed against the first plate and with the second plate.Type: GrantFiled: December 13, 2013Date of Patent: March 7, 2017Assignee: Volcano CorporationInventors: Dylan Van Hoven, Jeffrey H.

Patent number: 9307952Abstract: The present disclosure provides methods and apparatus of fabricating a transducer for use in ultrasound imaging. A substrate is provided. The substrate may be a silicon substrate having a first side and a second side opposite the first side. A transducer membrane is formed over the first side of the substrate. The transducer membrane includes a piezoelectric component. A well is formed in the substrate from the second side. A backing material is dispensed onto a first sidewall of the well in a manner so as to create a capillary effect that causes the backing material to wick down the sidewall, across the back side of the substrate exposed by the well, and up a second sidewall of the well. The transducer membrane is deflected so that the transducer membrane has a concave shape.Type: GrantFiled: December 13, 2013Date of Patent: April 12, 2016Assignee: Volcano CorporationInventors: Dylan Van Hoven, Jeffrey Brown, Paul Douglas Corl, Michael Reiter

Publication number: 20140187964Abstract: The present disclosure provides various embodiments of an ultrasound catheter for use in intravascular ultrasound (IVUS) imaging. An exemplary IVUS device includes an flexible elongate member having a lumen extending therethrough, and a rotatable imaging core disposed within the lumen. The imaging core is further configured to transmit and receive ultrasound signals through a distal portion of the flexible elongate member. The distal portion of the flexible elongate member includes a first set of material layers, while the proximal portion includes a second set of material layers different than the first set of material layers. The first set of material layers and the second material layers minimize distortion of the ultrasound signals. The first set of material layers further facilitates an average speed of sound through the first set of material layers that is substantially equivalent to a speed of sound through blood.Type: ApplicationFiled: December 20, 2013Publication date: July 3, 2014Applicant: Volcano CorporationInventors: Paul Douglas Corl, Dylan Van Hoven
