The Merit Medical Prelude PRO Sheath Introducer (REF PRO-4F-11) is a vascular access introducer sheath engineered to support diagnostic and interventional procedures requiring controlled arterial or venous entry. The Prelude PRO platform is designed to deliver a smooth transition from dilator to sheath, helping to minimize vessel trauma during insertion while providing a stable conduit for catheter exchanges.

Key Features
Low-profile introducer sheath configuration for vascular access procedures.
Hydrophilic coating on the sheath designed to reduce insertion friction and support atraumatic placement.
Integrated hemostasis valve intended to limit blood loss during device exchanges.
Side-port tubing with stopcock for flushing, aspiration, and contrast or medication administration.
Radiopaque marker to aid fluoroscopic visualization of the sheath tip.
Tapered dilator designed for smooth sheath-to-dilator transition.
Supplied with a compatible guidewire to facilitate standard Seldinger technique access.

Clinical Applications
Percutaneous introduction of diagnostic and interventional devices into the peripheral or coronary vasculature.
Supporting catheter exchanges during angiography and related interventional workflows.
Use within vascular access strategies selected by the treating physician in line with the manufacturer's Instructions for Use.
