Plain English Summary
Background and study aims
An intracranial aneurysm is a bulge in a blood vessel inside the brain, caused by a weakness in the vessel wall. There are three main treatment options available: observation/medical management, endovascular treatment, and surgical treatment. Although many aneurysms are treated surgically, an increasing number are treated by an endovascular approach, due to the invasive nature of the surgery and its increased risk of complications. In endovascular procedures, a catheter (small tube) is guided through the blood vessels to the location of the aneurysm and soft platinum coils are deployed into the aneurysm to trigger the formation of a blood clot, sealing off the aneurysm. However, the effectiveness of coiling is not as high as surgical clipping (where the aneurysm is sealed shut using a tiny metal clip), as there is an increased need to repeat the treatment. Despite this, endovascular treatment has been proven to improve patient outcomes. The LUNA™ AES provides an alternative to coiling, with the benefits of endovascular treatment but with improved wound healing at the aneurysm and thus a more durable blockage of the aneurysm. The aim of this study is to assess the safety, performance and effectiveness of the LUNA™ AES for the treatment of intracranial aneurysms.
Who can participate?
Patients aged 18 to 75 with an intracranial aneurysm
What does the study involve?
The LUNA™ AES is a small device that is delivered into the aneurysm through a small delivery tube. The device fills the aneurysm with the goal to reduce the risk of the aneurysm bursting and/or bleeding in the future while still maintaining good blood flow to the other blood vessels in the brain. The participant is monitored at various times during the study follow up (up to 36 months). A variety of tests are performed including one or more of the following: physical examination (including medical history), neurological (brain) tests, angiogram (a type of x-ray used to examine blood vessels).
What are the possible benefits and risks of participating?
Potential complications include but are not limited to the following: pain, infection, bleeding, adverse tissue reaction, blood vessel damage, stroke, aneurysm recurrence, unintended movement of the implant, unintended blood clot, and death
Where is the study run from?
Hopital de la Fondation Rothschild (France)
When is the study starting and how long is it expected to run for?
June 2011 to December 2016
Who is funding the study?
Covidien LP (USA)

Current interventions as of 24/04/2014:
The LUNA™ AES is a small device that is delivered into the aneurysm through a small delivery tube. The device fills the aneurysm with the goal to reduce the risk of the aneurysm bursting and/or bleeding in the future while still maintaining good blood flow to the other blood vessels in the brain. The procedure is similar to an angiogram. Using a guiding catheter and imaging, the LUNA™ AES device is placed into the appropriate location. At baseline and following the procedure, the participant is monitored at various times during the study follow up (up to 36 months). A variation of tests are performed and include one or more of the following: medical history collected, physical exam, pregnancy test (if applicable), neurological tests, angiogram and a modified rankin scale.

Primary outcome measure
Safety variables look at occurrence and frequency of:
1. Adverse Events (AEs)
2. Adverse Device Effects (ADEs)
3. Serious Adverse Events (SAEs)
4. Unanticipated Adverse Device Effects (UADEs)
Efficacy variables relate to the ability of the device to embolize the aneurysm at select time points
Secondary outcome measures
Performance variable evaluate the systems use in helping to get the device to aneurysm
