Patent number: 8819928Abstract: An intravascular ultrasonic imaging catheter is provided with a flexible circuit electrically coupled to a transducer array mounted on the distal end of the catheter, a portion of the flexible circuit being helically wound about the catheter in order to enhance the flexibility of the circuit. The catheter may be a balloon catheter which is also provided with a stent mounted on the balloon, the stent carrying one or more drugs designed to be eluted or washed into a patient's blood stream after the stent has been delivered, by a the balloon catheter, into a target area within the patient's vascular system.Type: GrantFiled: July 27, 2010Date of Patent: September 2, 2014Assignee: Volcano CorporationInventors: Elvin Nix, William Howes, Robert Dickinson, Stephan Wnendt

Publication number: 20120232400Abstract: Devices, systems, and methods for intravascular ultrasonic imaging are provided. In one embodiment, an apparatus for intravascular ultrasonic imaging is provided. The apparatus includes a flexible elongate member sized for insertion within a vasculature; an ultrasonic transducer array, mounted proximate a distal end of the flexible elongate member, wherein transducer elements of the ultrasonic transducer array comprise a non-polymeric electrostrictive material; and a high permittivity ceramic member that signally couples a common radiofrequency signal source to all elements of the transducer array simultaneously such that the common radiofrequency signal is provided through the ceramic member to all the transducer elements of the ultrasonic transducer array and a bias field is selectively transmitted to one or more of the transducer elements such that only transducer elements having the bias field applied to them will transform the common radiofrequency signal into an ultrasonic signal.Type: ApplicationFiled: February 21, 2012Publication date: September 13, 2012Applicant: Volcano CorporationInventors: Robert Dickinson, Elvin Nix

Patent number: 5306912Abstract: A thermal imaging device includes detector pixels A, B, C provided by a pyroelectric layer 1 arranged between electrode structures 3 and 4. A photoconductive layer 7 is provided between the electrode structure 5 and a further electrode structure 9. The device also includes an illumination source 11 for illuminating the photoconductive layer 7 for enabling pyroelectric charge developed by the detector pixels A, B, C to be optically addressed via the electrode structure 9. Optical addressing of the detector pixels obviates the need for solid state switching connections to each pixel, providing an imaging device readily capable of large scale fabrication.Type: GrantFiled: October 11, 1990Date of Patent: April 26, 1994Assignee: Thorn EMI plcInventors: Alastair Sibbald, Brian Holcroft, Elvin Nix, Stanley Taylor
