Study Summary

This trial will test the safety and effectiveness of a new device to treat aneurysms.

Who is the study for?
This trial is for adults aged 18-80 with a specific type of brain aneurysm that's wide-necked and saccular, measuring 6-12 mm. Participants must be stable if the aneurysm has ruptured (with a low Hunt & Hess Score) and agree to follow study procedures. Exclusions include pregnancy, other ongoing studies affecting outcomes, previous treatment of the target aneurysm, planned future treatments within a year, certain health conditions like coagulopathy or significant vessel disease.Check my eligibility
What is being tested?
The Citadel Embolization Device Study tests Stryker Neurovascular's new device designed for treating wide-neck intracranial aneurysms when used alongside Target Detachable Coils. The goal is to evaluate its safety and effectiveness in managing these complex cases.See study design
What are the potential side effects?
While not explicitly listed in the provided information, typical side effects from embolization devices may include reactions to contrast agents used during the procedure such as nausea or rash; bruising or bleeding at the catheter insertion site; clotting issues; and potential risks associated with endovascular treatments like stroke.

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Primary Effectiveness Endpoint of this study is adequate aneurysm occlusion without retreatment or significant parent artery stenosis (>50% stenosis).
Primary Safety Endpoint is stroke-related neurologic death, or major ipsilateral or disabling stroke in the territory supplied by the treated artery
Secondary outcome measures
Secondary Safety Endpoint of this study is any stroke event occurring through 12 months post-procedure, where a stroke event is defined as per what is noted in the description.
