Plain-language summary
The Esprit BTK PAS is a prospective, single-arm, multi-center observational study to assess the continued safety and effectiveness of the Espritâ„¢ BTK Everolimus Eluting Resorbable Scaffold System under commercial use, in patients with diseased infrapopliteal lesions causing CLTI (Chronic Limb-Threatening Ischemia) in a real-world setting. The clinical investigation will be conducted at up to 50 sites in the United States (US) and additional sites may be added outside of the US (OUS). Approximately 200 patients with a minimum of 50% of patients in the US will be registered in the clinical investigation.
