Complete LAA Occlusion

Mechanical Isolation

In preclinical and clinical studies, the AtriClip device securely sealed the LAA orifice resulting in a smooth endothelial tissue surface within 90 days. 1, 2, 3

Consistent/atraumatic force is equalized over tissue variations and trabeculation of the LAA. Parallel titanium crossbars apply adequate pressure without crushing or damaging tissue. Low-profile design allows for precise placement at the base of the LAA.



Non-piercing application greatly reduces the risk of tearing and bleeding.

Woven polyester fabric covering (used extensively in cardiac implants), promotes tissue ingrowth and achieves complete encapsulation in 180 days from implant, without risking erosion of adjacent structures.1, 3

Custom Fit to Specific Anatomy

AtriClip devices are available in four sizes, including 35mm, 40mm, 45mm and 50mm.
