The Next Generation of LAA Closure

The Conformal LAA Seal (CLAAS) builds on the success of 1st generation devices with an implant designed to conform to each patient’s anatomy and reliably seal the LAA. Our technology is intended to be easy to deliver and to reduce the need for procedural TEE and general anesthesia.

Clinical Objectives

CLAAS: Next Generation Design

CLAAS is designed to conform to each patient’s unique anatomy and  provide a consistent seal. Its foam matrix is intended to help ensure safe, atraumatic delivery, while its ePTFE cover provides a non-thrombogenic surface.
