MICHI™ Neuroprotection System (NPS+f) Filter Debris Analysis Study (The F-1 Study)
Overview
This study will be conducted in up to 10 hospitals in Europe, up to 75 patients will be enrolled. The purpose of the study is to evaluate any debris that may be captured in the inline filter of the MICHI(TM) Neuroprotection System with Filter (NPS+f) during its use in a transcarotid stenting procedure. The MICHI NPS+f is an embolic protection device that uses reverse flow to protect the brain during stenting of the Internal Carotid Artery. It is CE marked and is used in routine practice for the purpose of this study.
Study Type
- Study Type: Observational
- Study Design
- Time Perspective: Prospective
- Study Primary Completion Date: October 2013

- Device: MICHI(TM) NPS+f
- Transcarotid delivery system for carotid stents with flow reversal
- Procedure: transcarotid stenting
Arms, Groups and Cohorts
- MICHI(TM) NPS+f
- Patients routinely treated with the CE marked MICHI(TM) NPS+f System
Clinical Trial Outcome Measures
Primary Measures
- Percentage of patients with debris captured in the MICHI(TM) inline filter
- Time Frame: During MICHI(TM) NPS+f procedure
- The percentage of patients with any debris captured in the MICHI(TM) inline filter will be calculated
Secondary Measures
- Volume of debris captured in the MICHI(TM) inline filter
- Time Frame: During MICHI(TM) NPS+f procedure
- For all patients, where debris is captured in the MICHI(TM) inline filter, the volume of debris will be measured
- Histological analysis of debris captured in the MICHI(TM) inline filter
- Time Frame: During MICHI(TM) NPS+f procedure
- For all patients, where debris is captured in the MICHI(TM) inline filter, the type of plaque will be determined.
