The summary does not mention AI, ML, or any related concepts, and the device description is purely mechanical.
Yes
The device facilitates the placement of guidewires and assists in accessing the true lumen in the peripheral vasculature for medical procedures, which is a therapeutic intervention.
No.
The device is a re-entry catheter system intended to facilitate the placement and positioning of guidewires within the peripheral vasculature. Its function is to assist in accessing the true lumen after bypassing a chronic total occlusion, which is a therapeutic intervention, not a diagnostic one.
No
The device description explicitly states it consists of two physical components: a positioning balloon catheter and a micro-catheter lancet. These are hardware components, not software.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- Intended Use: The intended use clearly states that the device is used to facilitate the placement and positioning of guidewires within the peripheral vasculature. This is an in-vivo (within a living organism) procedure.
- Device Description: The description details a catheter system designed to be used inside the body to access the true lumen after bypassing an occlusion.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) outside of the body, which is the defining characteristic of an IVD.
Therefore, the OffRoad Re-Entry Catheter System is a medical device used for an interventional procedure within the body, not an IVD.
N/A
Intended Use / Indications for 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.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Study Type: Bench testing, biocompatibility testing, and pre-clinical animal testing. A prospective clinical study (Re-ROUTE, NCT01500031).
Sample Size:
Pre-clinical animal testing: N=7 (OffRoad Re-entry Catheter), N=5 (Cordis OUTBACK® LTD Re-Entry Catheter)
Clinical Study: 92 subjects
Key Results:
Pre-clinical animal testing: "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."
Clinical Study:
Primary Safety Endpoint: The composite rate of major adverse events (MAEs) related to the OffRoad System at 30 days was 3.3%. The single sample z-approximation one-sided 95% upper confidence bound was 6.5%, which was less than the threshold value of 15%, thus, the primary safety endpoint has been met.
Primary Effectiveness Endpoint: The site-reported device technical success rate was 84.8%. The single sample z-approximation one-sided 95% lower confidence bound was 79%, which was greater than the threshold value of 76%, thus, the primary effectiveness endpoint has been met.
Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)
Primary safety endpoint: MAE (Device-related) 3.3% (3/90), Upper 1-Sided 95% CI 6.5%b, Performance goal (PG) 15%.
Primary effectiveness endpoint: Device Technical Successa Site Reported 84.8% (78/92), Lower 1-Sided 95% CI 78.6%c, PG 76%. Core Lab Confirmed 92.1% (70/76), Lower 1-Sided 95% CI 87.0%, PG 76%.

| Device
Description | The OffRoad Re-Entry Catheter System consists of two components;
the OffRoad Positioning Balloon Catheter and the OffRoad Micro-
Catheter Lancet. 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. |

| 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.
