Abstract: A catheter assembly comprises a catheter (18), a needle (12) having a sharp distal tip disposed within the catheter (18), a catheter hub (14) connected to the catheter (18) having the needle (12) passing therethrough, the catheter hub (14) including a valve (38) that selectively permits or blocks a flow of fluid through the catheter (18), a valve actuator (54) that moves between a first position and a second position, and a return member (56) that returns the valve actuator (54) from the second position to the first position, and a needle protection member (176) that encloses the sharp distal tip of the needle (12).

Abstract: 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.
