The MARRS study is testing the Millipede System to help people who have had a severe stroke. A stroke happens when a blood vessel in the brain gets blocked, stopping oxygen from reaching parts of the brain, which can be very dangerous. This study will see how well the Millipede System can unblock these vessels and help people recover better. People who join will have to be between 18 and 85 years old and have specific conditions that qualify for the study.

• Participants should not have had a stroke in the last 3 months.
• The study involves using a special device to help reopen blocked vessels in the brain.
• Participants may have to visit the study site for evaluations and procedures.

Those who decide to participate will need to meet certain health criteria and must not have other conditions that could interfere with the study, like recent strokes, certain allergies, or severe health issues. If you think you might be eligible, you can talk to your doctor to learn more about joining this study.
