Intended Use

The Confida™ Adaptive Sheath is intended to provide a conduit through the iliofemoral vessels for the insertion of diagnostic or interventional devices used during cardiovascular procedures, including transcatheter aortic valve replacement (TAVR).

Device Story

Confida Adaptive Sheath is single-use, disposable, hydrophilically coated introducer sheath; provides flexible, hemostatic conduit for insertion of diagnostic/interventional devices (up to 18 Fr) into iliofemoral vasculature. Comprised of dilator with tapered distal tip for atraumatic tracking and sheath with hemostatic valve assembly to minimize blood loss. Sideport extension with three-way valve allows flushing. Used in hospital/healthcare facilities by professionals. Sheath body temporarily expands to accommodate devices; facilitates TAVR procedures. Benefits include reduced insertion/withdrawal forces via hydrophilic coating and minimized blood loss during procedure.

Clinical Evidence

Bench testing only. Evaluations included system pressure/leak/hemostasis, dimensional measurements, tensile strength, coating integrity, particulate testing, kink resistance, device/delivery system interaction forces, and simulated use (system recovery/functionality). Biocompatibility testing performed per ISO 10993-1:2009 (cytotoxicity, sensitization, intracutaneous reactivity, systemic toxicity, material-mediated pyrogen, hemolysis, PTT coagulation, complement activation, thromboresistance, and chemical characterization). In vivo design validation performed in an animal model. All acceptance criteria met.

Technological Characteristics

Hydrophilically coated sheath with hemostatic valve assembly; dilator with tapered tip. Accommodates 0.035in guidewires and up to 18 Fr devices. Sterilized by Ethylene Oxide (EtO) to SAL 10^-6. Surgically invasive, short-term use (<24 hours). Biocompatibility per ISO 10993-1:2009. Hemolysis and PTT testing per ASTM standards.

Indications for Use

Indicated for patients undergoing cardiovascular procedures, including TAVR, requiring iliofemoral vessel access for diagnostic or interventional device insertion. Contraindicated for unheparinized patients and patients with intolerance to anticoagulation therapy.

The Confida™ Adaptive Sheath is comprised of two components:

● Dilator component: The Dilator component includes a flexible, tapered distal tip that facilitates atraumatic tracking through the vasculature. The Dilator component contains an internal lumen able to accommodate up to a 0.035in (0.89mm) guidewire. Introducer Sheath component: A hydrophilic coating is applied ● to the sheath body to reduce the forces required for insertion into and withdrawal from the vasculature. The seal housing contains a hemostatic valve assembly designed to minimize blood loss during device use. The Introducer Sheath component contains a sideport extension with a three-way valve, providing a means for fluid to be flushed through the Introducer Sheath component during clinical use. The sheath body temporarily expands in diameter to allow the introduction and removal of devices up to 18 Fr in outer diameter, including devices used in TAVR procedures. There are no specific accessories required for use with the Confida™ Adaptive Sheath. The Confida™ Adaptive Sheath is designed for use with guidewires up to 0.035in (.89mm) in diameter, and has been developed for use with various devices used in diagnostic and interventional procedures, including TAVR procedures. The Confida™ Adaptive Sheath is classified as a surgically invasive device for short-term use (<24 hours) contacting circulatory blood, per ISO 10993-1:2009. The Confida™ Adaptive Sheath is sterilized by Ethylene Oxide (EtO) to a minimum sterility assurance level (SAL) of 10-6. The Confida™ Adaptive Sheath is intended to provide a conduit for the Statement of insertion of diagnostic and interventional devices into the vasculature and Intended Use: minimize blood loss associated with such insertions. Statement of The Confida™ Adaptive Sheath is intended to provide a conduit through Indications for Use: the iliofemoral vessels for the insertion of diagnostic or interventional devices used during cardiovascular procedures, including transcatheter aortic valve replacement (TAVR).
