What changed
The USPTO issued Patent 12,605,176 B2 to AtriCure, Inc., covering a method of positioning an occlusion clip at the left atrial appendage using a suction grasper with opposing jaws. The method involves creating an access port, delivering the suction grasper and occlusion clip via the port, grasping the appendage with suction, repositioning to apply tension, and clamping the base with the occlusion clip while tension is maintained.
Medical device manufacturers and surgical-equipment developers operating in the cardiac surgery space should review this patent when designing similar left atrial appendage occlusion or manipulation devices. Competitors developing suction-based graspers or occlusion clips for cardiac applications may need to assess whether their products fall within the scope of these 18 claims.

Abstract
A method of positioning an occlusion clip proximate a left atrial appendage may include creating an access port that exposes the left atrial appendage; delivering a suction grasper via the access port, the suction grasper including opposing jaws each having a suction port; delivering an occlusion clip via the access port; grasping the left atrial appendage via the suction grasper by applying suction to an exterior of the left atrial appendage so that a portion of the left atrial appendage interposes the opposing jaws while suction is applied via the suction ports; repositioning the suction grasper to tension the left atrial appendage; delivering an occlusion clip via the access port; clamping a base of the left atrial appendage using the occlusion clip while the suction grasper applies tension to the left atrial appendage; and/or egressing the suction grasper via the access port.
