The Merit Medical Prelude ACT Sheath Introducer (REF PSI-4F-11ACT) is a vascular access introducer engineered to streamline procedural workflow by enabling activated clotting time (ACT) blood sampling directly through the sheath. It combines the low-profile access characteristics of the Prelude family with a dedicated sampling capability intended to reduce the need for supplemental arterial punctures during interventional procedures.

Key Features
- 4 French inner diameter configuration for low-profile arterial access
- Designed to allow ACT blood sampling through the sheath assembly
- Hydrophilic or lubricious coating per Prelude platform design to support smooth insertion (refer to IFU for specifics)
- Integrated hemostasis valve to minimize blood loss and air ingress
- Side-port tubing with stopcock for flushing, aspiration, and medication delivery
- Radiopaque marker features to aid fluoroscopic visualization
- Supplied sterile for single use
- Packaged with a matched dilator and access components per manufacturer configuration

Clinical Applications
- Percutaneous arterial access for diagnostic and interventional catheterization procedures
- Radial, brachial, or femoral access workflows where short-length introducer sheaths are indicated
- Procedures requiring periodic ACT monitoring to guide anticoagulation management
- Supporting coronary, peripheral, and structural access scenarios as determined by the clinician
