TriGUARD 3™ Cerebral Embolic Protection Device by Keystone Heart
The Only Cerebral Embolic Protection Device Designed to Cover all Three Major Aortic Vessels
Keystone Heart’s TriGUARD 3™ Cerebral Embolic Protection Device is designed to provide full coverage of all three major aortic vessels to minimize the risk of cerebral damage during TAVR. The TriGUARD 3™ Cerebral Embolic Protection Device device is shaped to accommodate anatomic variations of the aortic arch. Formed to withstand potential interface with the TAVR delivery system and other procedure related accessories, it uses a Nitinol® frame and mesh — flexible and atraumatic, yet robust and sturdy.
The TriGUARD 3™ Cerebral Embolic Protection Device is placed via one of two femoral artery access ports typically used in TAVR, thereby eliminating the need for a third puncture site. It is designed to deploy rapidly and self-position through a small 8F catheter, and it provides stable, atraumatic protection with simple retrieval.

CAUTION – The TriGUARD 3™ Cerebral Embolic Protection Device is not commercially available. An investigational device for investigational use only.
