ClinConnect Summary

This clinical trial is studying the long-term safety and effectiveness of a device called the WEB Device, which is used to treat a specific type of brain condition called wide neck bifurcation intracranial aneurysms. These aneurysms are bulges in blood vessels in the brain that can be fragile and may cause serious health issues. The researchers want to see how well the device works at closing these aneurysms over one year after treatment.

To participate in this study, you need to be an adult (18 years or older) with either a ruptured or unruptured aneurysm that needs treatment. You'll need to provide written consent before any procedures are done. However, if you have certain medical conditions that could make you at high risk for strokes or if you've had recent bleeding in your brain, you may not be eligible to join. If you take part, you can expect to be monitored closely for any changes in your condition and to undergo imaging tests to evaluate how well the treatment is working over time.
