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 This study
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 Results may not be published yet.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
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This status has not been confirmed recently, so it may be out of date.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 looks at whether an AI-based tool that helps doctors shape a microcatheter can improve the safety and success of coil embolization, a procedure to treat brain aneurysms. Researchers will follow about 1,400 adults who are scheduled for this procedure, comparing cases where doctors shape the catheter using their own experience versus with AI assistance. The goal is to see if AI guidance reduces major complications like stroke and improves how completely the aneurysm is sealed off.

What this could mean

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

Active substance
AI-assisted microcatheter shaping simulation technology
What this could lead to
If AI-assisted shaping proves beneficial, it could become a standard tool to improve the safety and effectiveness of aneurysm coiling procedures.
What could go wrong
This is an observational study, so it can only show associations, not proof. Results may be influenced by differences in physician skill or patient characteristics, and the AI tool may not work equally well for all aneurysm types.

Study facts

What this study's own registry entry says, in plain language.

Participants

About 1,438 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Aug 2026

An estimate. Start dates often move.

Expected to finish

Dec 2029

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population will include adults with an intracranial aneurysm confirmed by computed tomography angiography, magnetic resonance angiography, or digital subtraction angiography who are scheduled to undergo coil embolization at participating study centers. Eligible patients will be enrolled prospectively after providing written informed consent. Participants will be classified into the physician-experience cohort or the AI-assisted cohort according to whether intelligent microcatheter shaping simulation technology is used during routine clinical care. Treatment strategy and use of the technology will not be assigned by the study protocol.

Ages

Children (under 18), adults (18 to 64) and older adults (65 and over)

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Age 18 years or older, with no restriction based on sex. 2. Diagnosis of an intracranial aneurysm confirmed by computed tomography angiography, magnetic resonance angiography, or digital subtraction angiography, with the target aneurysm planned for treatment by coil embolization. 3. Ability to understand the study requirements and treatment procedures and provision of written informed consent before any study-specific procedure. Exclusion Criteria: 1. Currently unable or expected to be unable to complete the 1-year follow-up. 2. Participation in another clinical study that may affect the results of this study. 3. Life expectancy of less than 1 year because of another disease or medical condition. 4. Considered unsuitable for participation by the investigator.
