Advancing the Treatment of Cerebral Aneurysms
Dark Sky Medical develops innovative endovascular technologies designed to improve the safety and effectiveness of aneurysm treatment.

A next generation aneurysm treatment device.
The Balloon Mesh is an adjunctive device designed to assist in aneurysm coiling procedures, combining the benefits of balloon and stent support without the tradeoffs of either.
Flow Preserving
The Balloon Mesh’s mesh structure jails coils inside the aneurysm sac without disrupting blood flow in the parent artery, eliminating ischemic risk.
Temporary
The Balloon Mesh is retrieved and removed from the patient at the end of the coiling procedure, making long-term dual anti-platelet therapy unnecessary.
Self-Expanding, Conformable Structure
The flexible mesh structure allows the Balloon Mesh to conform to different vessel diameters and tortuous anatomy, while producing low enough force to avoid vascular injury.

The Burden of Hemorrhagic Stroke
Hemorrhagic stroke accounts for roughly 20% of all strokes yet is responsible for nearly half of all stroke-related deaths, making it one of the most devastating cerebrovascular events a patient can experience.
- 1 in 50 Americans have an unruptured brain aneurysm.
- Hemorrhagic stroke causes 500,000 deaths worldwide each year.
- In the United States an aneurysm ruptures every 18 minutes.

“If this device was available, I would use it. Easy to deploy, trackable, and safe in ruptured cases.”

“The ability to have the balloon up and maintain flow is the ultimate goal.”
