Hydrogel Endovascular Aneurysm Treatment Trial (HEAT)
This research study is being done to test the effectiveness of a new generation FDA approved device for treating aneurysms compared to the current standard device for endovascular aneurysm treatment which is bare platinum coils. Endovascular procedures are a form of minimally invasive surgery, which is performed on blood vessels. The technique involves the introduction of a catheter which is a long, thin, flexible, hollow plastic tube through the skin into a large blood vessel. Typically the chosen blood vessel is the femoral artery found near the groin. The catheter is then maneuvered through the body to the location of the aneurysm in the brain using image guidance. Coils are delivered into the aneurysm through the catheters. Once the coils are delivered in the aneurysm, they are detached from the catheter. This is repeated until enough coils fill the aneurysm, blocking the blood flow to the aneurysm. The body responds by forming blood clots around the coil(s), which helps block the flow of blood into the aneurysm and keeps the vessel from rupturing or leaking. This study will compare the study device to the standard bare platinum coil to see which is better at preventing future rupturing or leaking. The study device is called the HydroCoil Embolization System and this study is a post-market clinical trial.
About 600 subjects from multiple institutions will take part in this study.

Your part in this study will last up to 24 months and will involve 6 visits (1 baseline visit before your surgery, the surgical procedure and 4 follow-up visits). These visits will occur at the same time as the visits you would receive as standard of care after your surgery.
If you are in this study, you will be placed in one of two study groups by chance using a process similar to the flip of a coin. This process is called randomization. Neither you nor the study staff will select the group you will be in. One group, the control group, will have their aneurysm treated by the bare platinum coils during their endovascular procedure. The other group, the study group will receive coils from the HydroCoil Embolization System. Both groups will receive the same standard of care and follow-up, but during the surgery different types of coils will be used.
