Device facilitates navigation through peripheral vasculature; benefits patient by enabling precise catheter placement during minimally invasive procedures.

Clinical Evidence

No clinical data. Substantial equivalence supported by bench testing, including surface, radiodetectability, fracture, flexing, tensile force, torque strength, torqueability, tip flexibility, sliding resistance, and particulate evaluation per ISO 11070:2014, ASTM F640-12, and USP <788>.

Technological Characteristics

Nickel-Titanium alloy core; polyurethane/tungsten and hydrophilic polymer coatings. Diameter 0.035"; lengths 260-450cm. Manual operation. Sterilized via Ethylene Oxide (ISO 11135:2014). Biocompatibility per ISO 10993-1:2009 (externally communicating, circulating blood, limited contact).

Indications for Use

Indicated for directing catheters to desired anatomical locations in peripheral vasculature during diagnostic or interventional procedures. Not for neurovascular or coronary interventions.
