What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved

Summary

This registry is following 4,000 people who have been treated with Medtronic devices for brain aneurysms or ischemic stroke. Researchers are tracking how well the devices work in everyday medical practice, including how often aneurysms are fully closed and how many patients regain independence after stroke. The goal is to better understand the long-term safety and effectiveness of these treatments.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this registry could provide real-world evidence to improve the safety and effectiveness of these neurovascular devices.
What could go wrong
This is an observational registry, not a controlled trial, so it cannot prove cause and effect. Results may be influenced by patient selection or other factors.

This is an AI summary of the original study and may miss details. Read our disclaimer.
