Keystone Heart – Cerebral Embolic Protection Device

Keystone Heart’s is an advanced cerebral embolic protection (CEP) device designed to minimize the risk of stroke during cardiovascular procedures, such as Transcatheter Aortic Valve Implantation (TAVI). The device features a nitinol frame and dome-shaped mesh deflector that effectively protects all three major cerebral arteries by preventing embolic debris, oxygen bubbles, or blood clots from reaching the brain. This innovation enhances patient safety and sets a new standard in cerebral protection.

Taga faced the challenge of creating a design that balanced the complex technical demands of the device with its single-use nature and strict usability requirements. Our work focused on developing a modular design with simplified assembly, eliminating the need for screws and enabling seamless snap-fit connections. By optimizing the device for cost-efficient mass production, we addressed the need for a straightforward yet reliable mechanism that ensures easy deployment during high-pressure procedures.

The intuitive “click-and-go” design ensures that the device can be assembled and stabilized with minimal effort, even with its intricate components and mechanisms. This approach not only streamlines manufacturing but also ensures that clinicians can rely on the device during critical interventions.
