The Merit Medical HeartSpan Fixed Curve Braided Transseptal Sheath (REF FCB8581ML1) is a single-use introducer sheath designed to facilitate the introduction of cardiovascular catheters through the interatrial septum during left-heart procedures. The braided shaft construction is engineered to provide a balance of column strength, torque response, and kink resistance, while the fixed curve geometry is intended to support stable positioning at the fossa ovalis and within the left atrium.

Key Features
- Braided shaft construction intended to support torque transmission and resist kinking during navigation.
- Fixed preformed curve to assist consistent orientation at the interatrial septum.
- Hemostasis valve and side-port stopcock for fluid management and aspiration.
- Tapered radiopaque dilator to facilitate atraumatic transition over a guidewire.
- Lubricious inner lumen intended to reduce friction during catheter exchanges.
- Sterile, single-use packaging.

Clinical Applications
- Transseptal access to the left atrium for catheter-based cardiovascular procedures.
- Introduction and support of diagnostic and interventional catheters across the interatrial septum.
- Use as an access platform during left-heart electrophysiology and structural workflows where a fixed curve sheath is indicated.
Refer to the manufacturer Instructions for Use for the complete list of indications, contraindications, warnings, and precautions.
