What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
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 This study
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 Results may not be published yet.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
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tested a new medical wire, called the Tarvos Microguidewire, used during surgery on blood vessels in the brain. The wire helps doctors guide other tools to the right spot. Researchers looked back at records of 121 patients who had this wire used in their surgery for conditions like brain aneurysms or stroke. The goal was to see if the wire works well and is safe.

What this could mean

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

Active substance
Tarvos Microguidewire (a thin wire used to guide other devices during brain blood vessel surgery)
What this could lead to
If successful, this wire could offer doctors a reliable tool for treating brain aneurysms, strokes, and other blood vessel problems.
What could go wrong
This is a small, retrospective study without a comparison group, so results may not apply to all patients. The wire is a tool, not a treatment itself.
