Intervention / Traitement
Description détaillée
L'AVC ischémique est une condition potentiellement mortelle. Chaque année, environ 795 000 personnes aux États-Unis subissent un AVC.
L'étude MARRS est une étude clinique interventionnelle, ouverte, à un seul bras, multicentrique et prospective. Les objectifs de l'étude sont d'évaluer les performances et les caractéristiques de sécurité du système Millipede chez les patients présentant un AVC ischémique aigu dû à des OVG et d'enregistrer les résultats cliniques.

ITT Cohort: Rate of Core Lab-adjudicated Reperfusion Success Within Three Passes
Délai: Intraprocedural

Proportion of subjects with successful reperfusion, defined as achieving a modified Thrombolysis in Cerebrovascular Infarction (mTICI) score of 2b or greater within ≤3 passes with the Millipede System without additional therapy.
The mTICI scale ranges from 0 to 3, with higher scores indicating better reperfusion: 0 = no perfusion, 1 = minimal perfusion, 2a = partial (<50%), 2b = substantial (≥50%), 2c = near complete, 3 = complete.
This measure reports the number of participants who achieved mTICI ≥2b under these criteria as adjudicated by an independent Core Lab.
