Intended Use

The Concentric Balloon Guide Catheter is indicated for use in facilitating the insertion and guidance of an intravascular catheter into a selected blood vessel in the peripheral and neuro vascular systems. The balloon provides temporary vascular occlusion during these and other angiographic procedures. The Balloon Guide Catheter is also indicated for use as a conduit for retrieval devices.

Device Story

Modified FlowGate Balloon Guide Catheter is a coaxial-lumen, braid-reinforced, variable stiffness catheter. Device features distal radiopaque marker for angiographic visualization and compliant balloon for temporary vascular occlusion. Proximal end includes bifurcated luer hub for flushing, inflation, and aspiration. Used in clinical settings by physicians to facilitate insertion/guidance of intravascular catheters and as a conduit for retrieval devices in peripheral and neurovascular procedures. Accessories include dilator, hemostasis valves, sheaths, and extension tubing. Device provides temporary vascular occlusion to assist in angiographic procedures, potentially improving procedural outcomes.

Clinical Evidence

Bench testing only. No clinical data. Verification and validation included dimensional verification, simulated use in neurovascular model, balloon performance (symmetry, compliance, fatigue, burst/leakage), tensile strength, shaft flexibility, tip deflection, tip patency, kink resistance, and accessory compatibility. Biocompatibility testing (ISO 10993) confirmed non-cytotoxic, non-sensitizing, non-irritant, non-pyrogenic, and non-hemolytic properties.

Technological Characteristics

Coaxial-lumen, braid-reinforced (stainless steel) catheter. Materials: Pebax (shaft/tip), Silicone (balloon), Platinum/Iridium (marker), Polyurethane (hub), Polyolefin/Pebax (strain relief). Cyanoacrylate used for braid securement. Sterilization: Ethylene Oxide (EtO). Dimensions: 7F, 8F, or 9F. Connectivity: None (mechanical device).

Indications for Use

Indicated for patients requiring intravascular catheter insertion and guidance in peripheral and neurovascular systems, temporary vascular occlusion during angiographic procedures, and as a conduit for retrieval devices.

Regulatory Classification

Identification

A percutaneous catheter is a device that is introduced into a vein or artery through the skin using a dilator and a sheath (introducer) or guide wire.
