The Merit Medical PreludeEASE Hydrophilic Sheath Introducer (REF PHR4F16021SC) is engineered to support clinicians performing radial and peripheral vascular access. The sheath incorporates a hydrophilic coating on the outer surface intended to lower insertion and withdrawal forces, helping clinicians navigate smaller or tortuous vessels. A tapered dilator and integrated hemostasis valve are designed to promote controlled access and minimize back-bleed during device exchanges.

Key Features
Hydrophilic outer coating intended to reduce friction at the access site
Tapered dilator designed for smooth transition across the vessel wall
Integrated hemostasis valve engineered to limit blood loss during exchanges
Side port with three-way stopcock for flushing and contrast administration
Kink-resistant sheath body intended to maintain lumen integrity during manipulation
Radiopaque marker to support fluoroscopic visualization
Supplied sterile for single-patient use

Clinical Applications
Introduction of interventional catheters and guidewires into the peripheral vasculature
Support of diagnostic and interventional coronary procedures via radial or femoral access
Facilitation of device exchanges during percutaneous interventions
Use in workflows where low-friction vascular access is preferred
