Is this trial a fit for you?

Likely a good fit

Patients with a single ruptured or unruptured intracranial aneurysm treated with a commercially available MicroVention device, where the physician has already chosen the device as the primary treatment.

Probably not a fit

Patients treated with different devices or who do not complete follow-up may not benefit from this registry.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational registry gathers data on functional, imaging, and safety outcomes from patients treated with MicroVention intracranial aneurysm devices. Data come from routine clinical care, without randomization or a predefined experimental protocol. The study focuses on outcomes after endovascular treatment and aims to reflect everyday practice. Ancillary devices used during procedures are not counted as primary treatment devices. Participation requires informed consent and follow-up visits as determined by treating physicians.

Why it matters

Potential benefit: If successful, the registry could provide real-world evidence to inform device safety and performance for clinicians and patients.

How similar studies have gone: Other real-world device registries have shown value in confirming safety and effectiveness across broader patient populations.

Note: For the purposes of this protocol, ancillary/accessory devices such as balloon catheters and other access devices are not considered primary treatment devices.
3. Patient or patient 's legally authorized representative (LAR) has provided written informed consent prior to treatment and no later than 48 hours post procedure for emergent treatment of ruptured aneurysms.
4. Patient must be considered by the treating physician to be available for and able to complete study follow-up visits.

Exclusion Criteria

1. Target aneurysm has been previously treated via surgical or endovascular means.
2. Patient is enrolled in another device or drug study in which participation could confound study results.
3. Patient has a life expectancy of less than 1 year due to other illness or condition (in addition to an intracranial aneurysm).
