Abstract
A catheter system may include a catheter adapter and a wing extending outwardly from the catheter adapter. The wing may include a groove or slot. The catheter system may include a needle hub and a paddle extending outwardly from the needle hub. The paddle may include an extension disposed within the groove or the slot to reduce axial movement between the catheter adapter and the needle hub, which may be advantageous during insertion of the catheter system into a patient. The extension may be removable from the groove or the slot to allow axial movement between the catheter adapter and the needle hub during removal of the needle hub from the catheter adapter, for example. The paddle and/or the wing may include a shape to reduce axial movement between the catheter adapter and the needle hub, which may also be advantageous during insertion of the catheter system.
