Intended Use

The OffRoad Re-Entry Catheter System is intended to facilitate the placement and positioning of guidewires within the peripheral vasculature beyond stenotic lesions, including sub and chronic total occlusions.

Device Story

OffRoad Re-Entry Catheter System comprises a positioning balloon catheter and a micro-catheter lancet; designed to assist in accessing the true lumen after bypassing chronic total occlusion (CTO) lesions in peripheral vasculature. Used by physicians in clinical settings during endovascular procedures. The device facilitates guidewire placement distal to CTOs; enables re-entry from a subintimal track into the true lumen. Benefits include improved technical success in recanalizing complex peripheral arterial occlusions. Performance is monitored via angiography; clinical decision-making relies on successful guidewire positioning to restore blood flow.

Clinical Evidence

Prospective clinical study (Re-ROUTE, N=92) evaluated safety and technical success in femoropopliteal CTOs. Primary safety endpoint: 30-day composite rate of major adverse events (MAE) was 3.3% (upper 95% CI 6.5%), meeting the 15% threshold. Primary effectiveness endpoint: site-reported technical success was 84.8% (lower 95% CI 79%), exceeding the 76% threshold. Core lab-confirmed technical success was 92.1%. Pre-clinical animal study (N=6 swine) confirmed successful re-entry into the true lumen with vascular effects similar to the predicate.

Technological Characteristics

System consists of a positioning balloon catheter and a micro-catheter lancet. Materials underwent biocompatibility testing (cytotoxicity, sensitization, reactivity, systemic toxicity, pyrogenicity, hemolysis, mutagenicity, hemocompatibility). Mechanical characteristics include tensile strength, balloon rated burst pressure, and torque. No specific ASTM standards cited. Device is a percutaneous catheter for peripheral vascular use.

Indications for Use

Indicated for patients with claudication or critical limb ischemia (Rutherford Category 2-5) requiring guidewire placement and positioning beyond stenotic lesions, including subintimal and chronic total occlusions (CTO) in the peripheral vasculature.

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.

Together they assist in accessing the true lumen after bypassing a chronic total occlusion lesion in the peripheral vasculature. | | Intended Use/ Indications for Use of Device | The OffRoad Re-Entry Catheter System is intended to facilitate the placement and positioning of guidewires within the peripheral vasculature beyond stenotic lesions, including sub and chronic total occlusions. | | Comparison of Technological Characteristics | The OffRoad Re-Entry Catheter System is substantially equivalent to the Cordis Outback Re-Entry Catheter (K083814) (the Predicate Device) that the Food and Drug Administration (FDA) has already cleared for use to facilitate placement and positioning of quidewires and catheters within the peripheral vasculature. The OffRoad Re-Entry Catheter System and the predicate device have the same intended use and similar indications, technological characteristics, and principles of operation. The minor technological differences between the OffRoad Re-Entry Catheter System and its predicate device do not raise any new issues of safety or effectiveness. | | Performance Data | Currently no FDA mandated or voluntary performance standards exist for this device. Bench testing, biocompatibility testing, and pre-clinical animal testing were performed to support a determination of substantial equivalence. The results of these tests provide reasonable assurance that the proposed device has been designed and tested to assure conformance to the requirements for its intended use. No new safety or performance issues were raised during the testing and, therefore, these devices may be considered substantially equivalent to the predicate devices. | {1}------------------------------------------------ The following biocompatibility and bench testing were completed on the OffRoad ™ Re-Entry Catheter System: Biocompatibility - MEM Elution Cytotoxicity Sensitization Intracutaneous Reactivity Acute Systemic Toxicity Materials Mediated Pyrogenicity USP Physicochemical Complement Activation Hemolysis (Direct Contact) Ames Mutagenicity Mouse Lymphoma Coaqulation In Vitro Hemocompatibility Partial Thromboplastin Time Natural Rubber Latex The following in-vitro performance tests were completed on the OffRoad™ Re-Entry Catheter System: Bench Tensile Strength Catheter Effective Length Deflation Time Balloon Rated Burst Pressure (RBP) Balloon Repeat Inflation Surface Finish and Cleanliness Balloon Catheter/Micro Catheter Compatibility Flexibility and Kink Shaft Outer Diameter (OD) Shaft to Y-Connector Tensile Strength Balloon Nominal Diameter Proximal Balloon Bond Tensile Strength Corrosion Guidewire Compatibility Sheath Compatibility Simulated Use and Coating Integrity Torque after Conditioning #### Particulate Evaluation #### Pre-Clinical Animal Testing BSC conducted a Preclinical study in naïve peripheral arteries of six common swine to evaluate the acute performance of the OffRoad™ Reentry Catheter System in comparison to the predicate Cordis OUTBACK® LTD Re-Entry Catheter. {2}------------------------------------------------ | Devices | Evaluation Criteria | OffRoad Testing Summary | |--------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | OffRoad™ Re-entry Catheter N=7 | Pass all required performance criteria during use: Device preparation Support product compatibility Proper positioning and use of Re-entry device Confirm re-entry Withdrawal after use | OffRoad received passing ratings for all performance criteria.

Withdrawal of all devices was rated acceptable | | Cordis OUTBACK® LTD™ Re-Entry Catheter N=5 | Histological characterization, and comparison of vessel wall effects after use of devices | Two instances of small arterial wall perforations associated with very limited perivascular hemorrhage near the site of re-entry were observed. Based on the data collected, neither perforation was considered a safety concern by the Study Pathologist and Study Director. | #### Study Results Conclusion: OffRoad and Outback devices met all protocol-specified evaluation criteria, and were used successfully to gain re-entry into the true lumen from within a vascular subintimal track created in the porcine naïve peripheral artery model. Vascular effects attributed to re-entry procedures using OffRoad and Outback devices were similar. Two instances of arterial wall perforations near the site of re-entry were observed, and were not considered a safety concern. This is based on the small size, limited perivascular hemorrhage, aggressive study procedures, which required creation of a subintimal track using a wire prior to any re-entry device use, and the fact that porcine non-diseased peripheral vessels are thinner than human diseased peripheral arteries. 1. 2 Results from the study support safety of the OffRoad™ Re-entry Catheter System during clinical use in the peripheral vasculature.
