Abstract
An intravenous catheter system may include a catheter adapter, which may be integrated. The intravenous catheter system may also include a housing coupled to a proximal end of the catheter adapter, an introducer needle having a proximal end, a distal tip, and a needle lumen extending between the proximal end of the introducer needle and the distal tip, a guidewire disposed within the housing and the needle lumen, and a guidewire advancement element. The housing may include a proximal end, a distal end, and a slot. A proximal end of the introducer needle may be secured within the housing. The guidewire advancement element may extend through the slot and be moveable along the slot in a distal direction to move the guidewire from a retracted position to an advanced position, in which the guidewire may extend beyond the distal tip.
