Patent number: 11872356Abstract: A medical instrument or device, such as a catheter, has echogenic properties, in addition to or as an alternative to radiopaque properties, to facilitate detection of the medical instrument or device during medical procedures using suitable imaging methods, such as ultrasound imaging and/or x-ray imaging methods. In example embodiments, an example catheter has a relatively increased radiopacity and echogenicity to facilitate a clinician with detecting the catheter with ultrasound imaging and/or x-ray imaging methods to assist the clinician with the insertion, placement, and/or maintenance of the catheter, for example.Type: GrantFiled: January 2, 2019Date of Patent: January 16, 2024Assignee: Becton, Dickinson and CompanyInventors: S. Ray Isaacson, Jeffrey C. O'Bryan, Ralph L. Sonderegger, Marc Weimer, Lawrence Trainer, Seth R. Strand
