About

The purpose of this study is to evaluate the safety and effectiveness of the HARBOR Occlusion Device for treating brain aneurysms. The HARBOR Device is investigational (experimental), meaning the Regulatory Authorities have not approved it for commercial use. The data collected in this research study will be used to analyze whether the HARBOR Device is safe and effective in treating brain aneurysms.

Full description

Nuvascular is sponsoring a prospective, single-center, single arm clinical trial to assess the safety and effectiveness of the HARBOR Occlusion Device for the treatment of unruptured intracranial aneurysms.

Enrollment: 10 estimated patients

Sex: All

Ages: 18 to 79 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Patient must be 18-79 years of age at the time of screening.

2. Patient must have a single unruptured IA requiring treatment. If the subject has an additional IA requiring treatment, the additional IA must not require treatment within 60 days of the index procedure.

3. The index IA to be treated must have the following characteristics:

   1. Saccular in shape
   2. Diameter 2.5 mm to 12.0 mm
   3. IA is appropriate for treatment with the HARBOR Occlusion Device per device Instructions for Use

4. Patient has an IA that is appropriate for treatment with HARBOR Occlusion Device without the use of additional implanted devices

5. Patient must be able to comply with all aspects of the screening, evaluation, treatment, and the post-procedure follow-up schedule. Patient must sign and date an IRB/EC-approved written informed consent prior to initiation of any study procedures.

6. Patient must sign and date an IRB/EC-approved written informed consent prior to initiation of any study procedures.

Exclusion criteria

1. Patient has a ruptured IA, defined as a patient with computed tomography (CT), magnetic resonance imaging (MRI), or lumbar puncture (LP) evidence of subarachnoid hemorrhage attributed to the index aneurysm within the last 180 days.
2. Patient has an IA with characteristics unsuitable for endovascular treatment.
3. Microcatheter could not reach patient's index aneurysm to allow necessary access to treat with study device.
4. Patient has vessel characteristics, tortuosity or morphology which could preclude safe access and support during treatment with study device;
5. Patient has vascular disease or other vascular anomaly so as to preclude the necessary access to the aneurysm for use of the study device.
6. Patient has clinical, angiographic or CT evidence of vasospasm, vasculitis, or intracranial tumor (except small meningioma) or any other intracranial vascular malformations on presentation.
7. Patient has conditions placing them at high risk for ischemic stroke or has exhibited ischemic symptoms such as transient ischemic attacks, minor strokes, or stroke-in-evolution within the prior 60 days.
8. Patient has any circulatory, neurovascular, cardiovascular, or neurologic conditions that have resulted in unstable neurological symptoms.
9. Patient has mRS ≥ 2 prior to presentation
10. Patient has had an SAH from a non-index IA or any other intracranial hemorrhage within 180 days.
11. Patient has physical, neurologic or psychiatric conditions which preclude his/her ability to comply with all aspects of the screening, evaluation, treatment, and the post-procedure follow-up schedule.
12. Patient has a known blood dyscrasia, coagulopathy, or hemoglobinopathy.
13. Patient is pregnant.
14. Patient has known hypersensitivity, which cannot be medically treated, to any component of the study implant device (primarily nickel-titanium alloy), procedural materials, or medications commonly used during the procedure.
15. Patient is concurrently involved in another investigational study or a post-market study that could affect the safety and effectiveness of IA treatment with the study device or with the study's follow-up schedule.
16. Patient has an acute life-threatening illness other than the neurological disease to be treated in this trial.
17. Patient has a life expectancy of less than 2 years due to other illness or condition (in addition to an intracranial aneurysm).
