AI Technical Summary
Existing left atrial appendage closure devices rely on a single post-deployment shape and dimensions, leading to improper closure and premature dislodgement, and lack the ability to adjust to individual anatomy, resulting in inadequate anchoring and pressure distribution.
A device with a central member and tissue ingrowth member that can change configurations from a pre-deployment to multiple post-deployment shapes, allowing for adjustable pressure and anchoring through extensions, barbs, and shape memory alloy components to secure the device within the left atrial appendage.
The device provides secure anchoring and adjustable pressure distribution, ensuring effective closure of the left atrial appendage, reducing the risk of dislodgement and improving fit with varying anatomies.
