Intended Use

The FlexCath Advance Steerable Sheath is intended for percutaneous catheter introduction into the vasculature and into the chambers of the heart. The sheath deflection facilitates catheter positioning.

Device Story

Sterile, single-use percutaneous introducer sheath and dilator; features integrated hemostasis valve and side-port with stopcock. Used in clinical settings by physicians for catheter introduction, withdrawal, and swapping; side-port allows continuous drip infusion, injection, flushing, aspiration, blood sampling, and pressure monitoring. Sheath deflection mechanism provides maneuverability for catheters advanced into heart chambers. Minimizes blood loss during procedures. Subject device incorporates design and material changes to hemostasis valve component compared to predicate.

Clinical Evidence

Bench testing only. Design verification testing included pressure decay, vacuum, kink, pull force, and insertion/retraction force testing. Biocompatibility testing performed per ISO 10993-1:2018 (cytotoxicity, sensitization, irritation, systemic toxicity, pyrogenicity, hemocompatibility). Sterilization qualification (EO residuals, bioburden, bacterial endotoxin) confirmed compliance.

Technological Characteristics

Sterile, single-use steerable sheath and dilator. Features handle-integrated hemostasis valve (modified design/material with silicone oil) and side-port with stopcock. Unidirectional deflection mechanism. Sterilized via validated EO cycle. Biocompatibility per ISO 10993-1:2018.
