Title:
ULTRASOUND IMAGING AND ATHERECTOMY METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/1994/007418
Kind Code:
A1
Abstract:
A catheter (30) for ultrasonic imaging has a transducer (54) fixed to a cutter (48). The transducer (54) is moved longitudinally within an artery while in a fixed radial position. Ultrasonic reflections are received and processed to display a planar or rectangular field of view image area of the artery. Other axial planes of the artery can be imaged by radially turning the transducer (54) to a different angular orientation within the artery and then longitudinally moving the transducer (54) to obtain an image of another planar field of view.
