Intended Use

The Microcatheter is intended for general intravascular use, including peripheral and coronary vasculature. Once the subselective region has been accessed, the microcatheter can be used for the controlled and selective infusion of diagnostic, embolic or therapeutic materials into vessels. The catheter should not be used in the cerebral vessels.

Device Story

Maestro Microcatheter is a sterile, single-use intravascular catheter; available in 2.8F/2.1F sizes and various lengths (110cm, 130cm, 150cm). Features include hydrophilic coating on distal 80cm shaft, radiopaque distal tip marker for fluoroscopic visualization, and molded winged hub with strain relief. Distal tip configurations include straight, 45-degree, or swan neck. Used by physicians in clinical settings to access subselective regions of peripheral or coronary vasculature; facilitates controlled infusion of diagnostic, embolic, or therapeutic agents. Device provides mechanical pathway for delivery of coils, microspheres, and particles. Benefits include precise navigation and targeted delivery of therapeutic materials to specific vascular sites.

Clinical Evidence

Bench testing only. No clinical data provided. Performance testing included surface, tensile force, dimensions, radio-detectability, leakage, flow rate, kink resistance, lubricity, coating coverage, delivery of microspheres/particles/coils, torque strength, particulate, tip shape retention, hub migration, guidewire/catheter compatibility, torsion, negative pressure collapse, hoop removal, tip straightener, trackability, and pushability. All tests met predetermined acceptance criteria.

Technological Characteristics

Intravascular catheter; 2.8F proximal/2.1F distal diameter. Features hydrophilic coating, radiopaque distal marker. Materials meet ISO 10993 biocompatibility standards. Sterilized via ethylene oxide (ISO 11135, ISO 10993-7). Complies with ISO 10555-1 for general requirements. Mechanical design includes winged hub and tapered strain relief.

Indications for Use

Indicated for patients requiring general intravascular access in peripheral and coronary vasculature for controlled infusion of diagnostic, embolic, or therapeutic materials. Contraindicated for use in cerebral vessels.

Regulatory Classification

Identification

A continuous flush catheter is an attachment to a catheter-transducer system that permits continuous intravascular flushing at a slow infusion rate for the purpose of eliminating clotting, back-leakage, and waveform damping.
