Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

IMPACT is an observational, post market study designed to provide an ongoing safety and performance evaluation of Stryker Neurovascular devices used for the treatment of intracranial aneurysms with an endovascular approach.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

IMPACT is an international, prospective, observational, multicenter, non-randomized, post market study designed to provide ongoing safety and performance evaluation on implantable devices used for the treatment of intracranial aneurysms with an endovascular approach. Data collection will also include details on adjunctive and ancillary devices used.

In addition, to gaining safety and performance data, this study will provide clinical evidence that may assist physicians in selecting an appropriate device(s) while describing treatment options used to treat patients with intracranial aneurysms.

Study Groups

Evolve EU

Selected hospitals for participation

Endovascular treatment of intracranial aneurysms using a flow-diverting stent

Intervention Type DEVICE

The flow diverter brings about a reduction of blood flow to the aneurysm, which progresses over time into forming a stable thrombus within the aneurysm, as well as eventual aneurysm scarring and retraction. The flow diverter also acts as a scaffold for tissue growth across the neck of the aneurysm, which blocks the aneurysm from the artery blood flow.

Endovascular treatment of intracranial aneurysms using a flow-diverting stent

Intervention Type DEVICE

The flow diverter brings about a reduction of blood flow to the aneurysm, which progresses over time into forming a stable thrombus within the aneurysm, as well as eventual aneurysm scarring and retraction. The flow diverter also acts as a scaffold for tissue growth across the neck of the aneurysm, which blocks the aneurysm from the artery blood flow.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Subject has an intracranial aneurysm that can be treated with one of the proposed devices
* Subject age is ≥ 18 years
* Subject or subject's legally authorized representative (LAR) has signed written informed consent
* Subject is willing to comply with scheduled visits and examinations per institutional standard of care

Exclusion Criteria

* Subject is pregnant or plans to become pregnant her study participation\*.
* Subject is currently enrolled in or plans to be enrolled in a concurrent drug or device study.
* Subject has a condition which will not allow him/her to comply with his/her post-procedure follow up per the institutional standard of care (medical condition, subject living abroad and unable to return for follow-up, e.g.).
* Subject has a non-target aneurysm treated within 30 days prior to study enrollment.
* Subject has a planned treatment of a non-target aneurysm in the same vascular territory during participation in the study.
* Subject target aneurysm is a ruptured intracranial aneurysm (unless ruptured at least 21 days prior the day of the index procedure)
* Subject has a target aneurysm other than saccular or fusiform intracranial aneurysms; e.g.: vertebrobasilar dolichoectasia (VBD)
* The parent vessel size does not fall within the indicated range defined by IFU
* Antiplatelet and/or anticoagulation therapy (e.g., aspirin and clopidogrel) is contraindicated for the subject
* Subject has not received dual anti-platelet agents prior to the procedure or equivalent in accordance with standard medical practice
* Subject has an active bacterial or viral infection
* The angiography demonstrates the anatomy is not appropriate for endovascular treatment, due to conditions such as:
* Severe intracranial vessel tortuosity or stenosis; and/or
* Intracranial vasospasm not responsive to medical therapy


* Subject has a non-target aneurysm treated within 30 days prior to study enrollment
* Subject has a planned treatment of a non-target aneurysm in the same vascular territory during participation in the study
* Subject has a modified Rankin Score (mRS) ≥3 at pre-procedure examination
* Subject has undergone previous stent assisted coiling or flow diverter treatment of a parent artery aneurysm near the location of the target aneurysm
