The Caterpillar™ and Caterpillar™ Micro Arterial Embolization Devices are self-expanding arterial occlusion plugs intended for use in the peripheral vasculature. The devices consist of the following components and are indicated to be a permanent implant: cobalt-chrome stem, nickel-titanium fibers, platinum-iridium radiopaque marker bands, and a polyurethane and polyethylene occlusion membrane. The Caterpillar™ and Caterpillar™ Micro Arterial Embolization Device Systems are packaged as a single unit with the implant, loader, dispenser hoop, detachable delivery wire, and torque tool. Innovative Dual-action Design for Rapid Occlusion * The Caterpillar and Caterpillar Micro Arterial Embolization Devices have an innovative dual-action design with opposing nitinol fiber segments and an occlusion membrane to help support rapid embolization and provide a balance between placement accuracy and deliverability in tortuous anatomy. * * In an arterial ovine Good Laboratory Practice (GLP) study with devices implanted according to labeled vessel diameters, full occlusion at 10 minutes was achieved with all Caterpillar™ and Caterpillar™ Micro Arterial Embolization Devices (14/14). Full occlusion defined as no perfusion – no antegrade flow beyond point of occlusion. Placement accuracy and track forces were measured through pre-clinical bench studies using either an anatomical splenic artery or right gastric artery model. Pre-clinical data and bench testing may not be indicative of clinical performance. Different test methods may yield different results. Data on file, Bard Peripheral Vascular, Inc.
