Brief Summary
The primary objective of this clinical investigation is to evaluate the early safety and feasibility of the LuSeed Aneurysm Embolization System for treating unruptured intracranial aneurysms (IA). This is a single-arm, open-label, single-center, interventional study, screening patients approved for treatment of unruptured IAs based on national or international guidelines. Up to 10 eligible subjects meeting inclusion and exclusion criteria and providing consent will be enrolled in a Canadian site.

Eligibility Criteria
You may qualify if:
- Patients indicated for treatment of unruptured intracranial aneurysms (IA) according to AHA / ASA Guidelines.
- Age 18-80 years at screening
- Patients who are suitable for non-emergency endovascular embolization of saccular IAs
- The IA must have had the following characteristics:
- IA located in bifurcation in the anterior or posterior circulation
- IA dimensions appropriate for treatment with LuSeed- Vascular Embolization Device per implant size selection guidelines as outlined in the Instructions for
- Use (IFU) and as follows:
- IA Width: 2.5-5.5\[mm\]
- IA Neck: 2.0-5.0\[mm\]
- IA Height: min 4.0 \[mm\]- device short configuration, min 5.0 \[mm\]-device long configuration • The AI must meet the definition of a "wide-neck" aneurysm.
- Patient is willing and able to participate in the study for the duration of the study follow-up and can comply with study requirements
- Patient able to give their informed consent can be included in this study.
You may not qualify if:
- Ruptured intracranial aneurysm
- Patient anatomy or physiology considered unsuitable for endovascular treatment as determined by imaging Core Lab
- Contraindication for arterial access
- Intracranial aneurysm neck diameter less than 2mm or greater than 5 mm
- Intracranial aneurysm sac diameter less than 2.5mm or greater than 5.5mm
- Intracranial aneurysm minimum height less than 4.0 mm
- Target Intracranial aneurysm contains other devices/implants (e.g., coils)
- Stenosis of the target IA's parent vessel \>50%
- Known allergy to platinum, nickel, or titanium
- Known allergy to contrast agents
- Absolute contraindication to anticoagulation or antiplatelet therapy
- Anticoagulation medications such as warfarin that cannot be discontinued
- Pregnant, breastfeeding or planning pregnancy within next 12 months
- Acute or chronic renal failure (stage III or IV by VARC-3 criteria)
- Cerebral embolism, stroke, or TIA in past 6 months
- +7 more criteria
