Left Atrial Appendage Occlusion Device

Tech ID: sie000664



The left atrium of the heart has a connected pouch-like structure called the left atrial appendage (LAA). Blood flows between the left atrium and the LAA in the normal operation of the heart. During atrial fibrillation, a common cardiac arrhythmia the irregular beating of the heart can result in some stagnant blood in the LAA. This lack of blood flow can lead to the formation of blood clots. These blood clots travel out of the heart and into the body causing stroke, heart failure, and other complications. LAA occlusion is a way to reduce strokes by closing the pouch where the blood pools.



This device reduces the risk of deadly strokes in patients by closing the opening of the LAA and preventing blood pooling. It consists of a low-profile catheter that positions a balloon-like structure into the opening of the LAA to block it. The device prevents clots from traveling out of the heart and into the body. The device allows at-risk patients to be free from taking blood-thinning medications to prevent these blood clots.


Stage of Development

Concept only.



Low profile catheter design makes for an easier to use LAA Occlusion device as compared to current solutions.



The concept can be developed into a competitive LAA Occlusion device.
