Post Market Registry Study of Intracranial Aneurysms Treated With Sugita Clipping Devices (T2_PMCF)

February 5, 2026 updated by: Mizuho Corporation
The objective of this study is to verify the performance and safety of the Sugita Aneurysm Clips devices when used as intended and to identify possible risk factors. Data collected will be used to support the continuing performance and safety of the devices in the post-market use environment in Europe. Subjects who have an intracranial aneurysm that the physician intends to treat with the subject devices will be included in the study. Subjects will be followup as per hospital standard of care for 5 years.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

  • Subject has an intracranial aneurysm (ruptured or unruptured) that can be treated with one of the proposed devices.
  • Subject is adult, ≥18 years.
  • As per national regulations, subject or subject's legally authorized representative (LAR) has signed written informed consent.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Aneurysm clipping is a surgical procedure used to treat brain aneurysms.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Rate of permanent aneurysm occlusions
Time Frame: Up to 12 months
Rate of complete permanent aneurysm occlusions according to Molyneux et al, 2005, where the category of occlusion is selected as "Complete occlusion".
Up to 12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Incidence of adverse events
Time Frame: up to 60 months
The number and percentage of subjects experiencing any adverse event. Each adverse event type, including severity will be reported.
up to 60 months
Change in Modified Rankin Scale
Time Frame: through 60 months
The mean, standard deviation, median, minimum, maximum, and number of evaluable observations will be reported for baseline and to each follow up visit using descriptive statistics.The absolute change from baseline will be calculated for each subject at follow up visits.
through 60 months
Amount of aneurysm retreatments
Time Frame: through 60 months
The amount of aneurysm retreatments will be reported as 0, 1 and >=2 retreatments through each follow up visit.
through 60 months
Procedure success rate
Time Frame: within 1 week after clipping
Rate of successful aneurysm occlusions per Molyneux classification "Complete occlusion" while using a permanent clip. Frequency counts and percentages of subjects, as well as 95% confidence intervals for the percentages will be presented.
within 1 week after clipping
Rate of successful applications of temporary clips
Time Frame: Within 1 week after clipping
Subjects that experience a successful aneurysm occlusion according to Molyneux classification "Complete occlusion" while using temporary clips.
Within 1 week after clipping

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
