Patent number: 10773055Abstract: The present invention is directed to an echogenic member assembly for use with a catheter assembly. The echogenic member assembly includes at least one echogenic member having a cylindrical body extending between a first end and a second end. Thus, the body defines a longitudinal length between the first and second ends. Further, the cylindrical body has an exterior surface extending from the first end to the second end. The exterior surface includes a plurality of discontinuities arranged in a predetermined pattern so as to enhance ultrasonic imaging. In addition, the longitudinal length of the echogenic member is less than a total length of a catheter of the catheter assembly. As such, the echogenic member provides enhanced ultrasonic imaging to the catheter assembly without compromising the inherent flexibility of the catheter.Type: GrantFiled: June 18, 2015Date of Patent: September 15, 2020Assignee: Avent, Inc.Inventors: Steve S.
