Clinical Feasibility Evaluation of the Gentuity HF-OCT Imaging System With Vis-M Micro-Imaging Catheter

This study is a prospective, single arm, unblinded, and open-label study. The study is designed to evaluate the use of the Gentuity Neurovascular Imaging System in patients undergoing elective neurointerventional diagnostic procedures.

Study Overview

• Status: Recruiting
• Conditions: Anatomy
• Intervention / Treatment: Device: HF-OCT Imaging System with Vis-M Micro-Imaging Catheter

Detailed Description

Patients undergoing elective, neurointerventional procedures, or patient undergoing follow-up diagnostic procedures who meet all inclusion criteria and none of the exclusion criteria will be considered for enrollment. The study investigates the use of the Gentuity Neurovascular Imaging System as a diagnostic tool for intravascular imaging in the cerebrovasculature. The study evaluates the incidence and severity of device-related adverse events, clinical usability performance and technical performance of imaging quality.
