US 2026/0294436 A1 · LEFT ATRIAL APPENDAGE OCCLUSION

Abstract

A medical system, device and method are described for occluding a left atrial appendage. An example medical device, such as an occlusion device, may include a first catheter with an elongate tubular body and a central lumen that extends from a proximal end to a distal end arranged to be positioned at an opening of the left atrial appendage. A deployable balloon may be arranged at the distal end of the catheter and is operable to seal against an opening of the left atrial appendage. An aspiration source attached to the central lumen of the catheter is operable to at least partially evacuate and collapse the left atrial appendage. A steerable delivery catheter may be arranged to deliver adhesive within the partially collapsed left atrial appendage to thereby occlude the left atrial appendage.
