Catheter Insertion Device Having Continuous Flashback

A catheter insertion device comprising:

• an inner body defining a continuous pulsatile blood flashback chamber;
• a needle hub having a proximal end attached to a distal end of the inner body;
• a hollow introducer needle extending from a distal end of the needle hub, the introducer needle having a tip configured to pierce a wall of a blood vessel;
• a catheter configured to slidably fit over the introducer needle, the catheter extending from a catheter hub;
• an outer body configured to slidably receive a portion of the inner body;
• a guidewire coupled to a proximal end of the outer body;
• and
• a stabilizer coupled to a proximal end of the inner body, the stabilizer comprising a passage configured to receive the guidewire;
• wherein the outer body is further configured to move between a first position in which the guidewire is at an undeployed state and a second position in which the guidewire is at a deployed state;
• wherein a tip of the guidewire is located within the needle when the outer body is at the first position;
• wherein the tip of the guidewire is advanced beyond the tip of the needle when the outer body is at the second position;
• and
• wherein the passage of the stabilizer is configured to provide frictional resistance to the guidewire when the outer body moves between the first position and the second position.
