1. A catheter insertion device for inserting a catheter into an introducer, the catheter insertion device comprising:
an elongate shaft extending along a shaft longitudinal axis, wherein the elongate shaft comprises a shaft proximal end opening aligned with the shaft longitudinal axis and a shaft distal end opening aligned with the shaft longitudinal axis, wherein the elongate shaft defines an elongate shaft lumen that is aligned with and connects the shaft proximal end opening and the shaft distal end opening, wherein the elongate shaft is configured to accommodate the catheter in an inserted configuration in which the catheter extends through the shaft proximal end opening, the elongate shaft lumen, and the shaft distal end opening, and wherein the elongate shaft defines a side opening in a wall of the elongate shaft;
an elastic member that covers the side opening to block access to the elongate shaft lumen through the side opening, wherein the side opening and the elastic member are configured to accommodate hand depression of the elastic member to displace an inner surface of the elastic member through the side opening and into the elongate shaft lumen; and
a bleedback valve that includes an outer circumferential surface, wherein the bleedback valve is disposed in a distal end portion of the elongate shaft lumen, wherein the bleedback valve defines a radially expandable lumen longitudinally extending through a center of the bleedback valve, wherein the bleedback valve is configured to accommodate the catheter within the radially expandable lumen in the inserted configuration of the catheter, and wherein the radially expandable lumen is configured to inhibit flow of blood through the radially expandable lumen.
