Intended Use

The Micro Guide Catheter ELITE accessory is to be used with the Frontrumer® CTO Catheter. The Frontrumer® CTO Catheter is intended to facilitate the intraluminal placement of conventional guide wires beyond stenotic lesions (including chronic total occlusions) in the peripheral vasculature prior to further percutaneous intervention.

Device Story

Micro Guide Catheter ELITE is a single-lumen, torqueable percutaneous catheter used as an accessory to the Frontrunner® CTO Catheter. It facilitates guidewire placement and provides support during peripheral vascular procedures. The device features a PTFE inner liner, stainless steel braid, polymer jacket, and hydrophilic coating. A proximal molded hub with luer fitting allows for flushing and maneuvering; a distal radiopaque marker band enables fluoroscopic visualization. Used in clinical settings by physicians, the device is advanced through the vasculature to navigate stenotic lesions. By providing structural support and trackability, it assists in crossing chronic total occlusions, potentially improving procedural success in peripheral interventions. The device is provided sterile for single use.

Clinical Evidence

Bench testing included biocompatibility (cytotoxicity, hemolysis, USP <661>), dimensional, and functional testing (tensile, leak, coating integrity, lubricity, stiffness, kink, torque, corrosion, particulate, simulated use). A GLP animal study in a porcine model (n=2) evaluated performance in the peripheral vasculature, comparing 2 test and 2 control articles. Endpoints included radiopacity, maneuverability (rotate, advance, retract), and vessel trauma. Results showed no procedure-related complications, no tissue damage, and no perforation, demonstrating that the modified tip and stiffness do not increase risk.

Technological Characteristics

6F sheath compatible, single-lumen catheter. Materials: PTFE inner liner, stainless steel braid, polymer jacket, hydrophilic coating. Features: molded hub with luer fitting, radiopaque marker band. Sterilization: Ethylene Oxide (EO). Connectivity: None (mechanical device).

Indications for Use

Indicated for use with the Frontrunner® CTO Catheter to facilitate intraluminal placement of conventional guidewires beyond stenotic lesions, including chronic total occlusions, in the peripheral vasculature prior to percutaneous intervention.

# Animal Study

Cordis conducted a GLP animal study to evaluate the performance of Micro Guide Catheter Elite under simulated conditions in a porcine model. Two animals were utilized for the acute evaluations in the peripheral vasculature. Four devices (2 test articles and 2 control articles) were evaluated in each animal and scored for radiopacity and the ability to rotate, advance and retract the devices. No procedure-related complications or deaths were reported. Evaluation arteries were grossly evaluated in situ, and following excision, they were longitudinally cut and evaluated for signs of damage or trauma. There was no evidence of tissue damage or perforation. This study demonstrated that the angled tip and added stiffness of the Micro Guide Catheter ELITE relative to the predicate device does not increase the risk of vessel damage or perforation.

# VIII. CONCLUSIONS

The subject Micro Guide Catheter ELITE is the same in basic design and identical intended use as the legally marketed predicate, Micro Guide Catheter XP. The minor modifications made to the catheter shaft and tip and improved packaging design for Micro Guide Catheter ELITE product family do not alter the fundamental scientific technology of the device's operating principles, mechanism of action, or the indication for the use of device. The design modifications made to the Micro Guide Catheter ELITE were verified and validated through a series of tests ensuring that the subject catheter meets the specifications and that the performance and functionality are substantially equivalent to the predicate device. The Micro Guide Catheter ELITE continues to meet all previous performance specifications, and none of the critical clinical performance parameters have changed. The modifications do not raise new questions of safety and effectiveness. Micro Guide Catheter ELITE can be used according to its intended use and in an equivalent manner to the predicate device.
