Is this trial a fit for you?

Likely a good fit

Adults (≥18 years) undergoing TCAR with the ENROUTE Neuroprotection System and a Boston Scientific carotid stent, enrolled with informed consent.

Probably not a fit

Patients not receiving TCAR with ENROUTE or not meeting enrollment criteria may not benefit from the data generated.

What this trial studies

This global, prospective registry collects real-world data on TCAR procedures using the ENROUTE Neuroprotection System, across multiple centers, without randomization. It aims to describe outcomes and health economics in adults with extracranial carotid artery disease where TCAR results are not well reported. Data will come from patients treated with ENROUTE alongside commercially available carotid stents, with follow-up aligned to registry protocols. The study is non-interventional and observational, focusing on routine clinical practice outside of a controlled trial setting.

Why it matters

Potential benefit: If successful, it could clarify real-world safety and effectiveness of the ENROUTE system in TCAR and inform clinical and payer decisions.

How similar studies have gone: Previous real-world registries in TCAR and neuroprotection devices have provided actionable insights, though this specific combination is less extensively studied.
