Abstract

A catheter insertion device (10) includes a housing (12) with a base (14), a catheter (28), an introducer needle (30) and an actuator (26) mounted within the housing. The catheter (28) and needle (30) are coupled to the actuator (26) and movable between a first position where the catheter and needle are retracted within the housing and a second position where the catheter (28) and needle (30) extend from the housing, and where the needle retracts into the actuator when the catheter and needle reach the second position. A spring (90) is provided in the housing (12) or the actuator (26) where the spring (90) is released after deployment of the device to retract the needle (20) with respect to the catheter (28).
