The Stiletto Extended Dwell Catheter (EDC) is a sterile, single use device designed to allow users to sample blood and/or administer fluids over a short duration (<28 days) through a peripherally inserted catheter. The Stiletto EDC utilizes an introducer needle and sheathing cannula to support advancement of a single lumen, power-injectable catheter into peripheral vasculature. Unique catheter tip geometry is employed that works in conjunction with a sheathing cannula to provide support as the catheter advances into the vessel, providing a reliable method of insertion without need of a guidewire. The catheter, hub, and insertion components are integrated into a single housing to enhance ease of use.
