Abstract
A catheter insertion device includes a housing, a needle, a guide wire, and a catheter disposed coaxially over the needle. The needle has a proximal end in the housing and a distal end extending from a distal end of the housing in an insertion position. The guide wire has a distal portion disposed in a lumen of the needle in a withdrawn position. The guide wire may include a safety tip having a non-coiled configuration in the withdrawn position and a coiled configuration in an advanced position. The catheter insertion device may include a sliding member attached to the guide wire, wherein movement of the sliding member translates the guide wire from the withdrawn position to the advanced position.
