AI Technical Summary

Technical Problem

Existing occlusion devices for the left atrial appendage (LAA) fail to preserve its functionality, leading to risks such as thromboembolism, device migration, and leakage, while conventional embolic protection devices risk dislodging debris during retrieval, and current intracardiac echocardiography catheters have limited image quality due to small transducer size, and aortic valve replacements require rigid prosthetics that can cause complications.

Method used

The LAA occlusion device features a high-compliance, non-traumatic frame implanted deeper into the LAA, minimizing trauma and preserving functionality, while the embolic protection device uses a flexible filter with a porous mesh to capture debris without deflecting it, and the catheter employs larger transducers and advanced pull-wire mechanisms for improved maneuverability and imaging, and aortic valve replacements use smaller, non-traumatic anchors and leaflet augmentation.

Benefits of technology

The LAA occlusion device reduces thromboembolism and preserves functionality, the embolic protection device minimizes debris dislodgement, and the catheter enhances imaging and maneuverability, with aortic valve replacements reducing complications by securing without rigidity and enabling blood flow.

Abstract

Cardiovascular devices and methods. A prosthetic aortic valve that attaches to the valve leaflet using an actuating arm and gripper, reducing device migration and size fit issues. This involves excising the affected leaflet prior to implantation to ensure blood flow to the coronary arteries and provides optical visualization. The valve features replaceable leaflets and a streamlined frame. Innovative left atrial appendage devices, embolic protection devices, intracardiac echocardiography devices, and maneuverable catheter devices are introduced. Provided herein are a non-traumatic contractile mitral annulus repair device, a non-invasive method for correcting in vivo calcium using electromagnetic energy, and a system for optical visualization during vascular intervention by displacing blood with a clearing fluid.
