Abstract
A catheter system may include a catheter assembly and a needle assembly. The needle assembly may include a cover disposed over a push button. An inner surface of the cover may include a projection, and the cover may be configured to slide proximally. In response to the cover sliding proximally, the projection may be configured to contact the push button, and the push button may be configured to depress. The push button may include a living hinge. The housing may include a flange contacting a proximal end of the push button to prevent the proximal end of the button from being depressed. In response to bending of the living hinge, the push button may be configured to move distal to the flange and depress. In response to depression of the push button, the needle hub may move proximally within the barrel to retract the introducer needle.
