AI Technical Summary

Technical Problem

Cerebral embolism is a known complication of cardiac surgery and catheter-based interventional procedures, with embolic particles entering the bloodstream and causing neuropsychological deficits, stroke, or even death, necessitating an integrated embolic protection system that does not increase the catheter's diameter and avoids additional procedural steps or access sites.

Method used

A prosthetic heart valve delivery catheter with an integrated embolic filter, featuring a self-expanding or balloon-expandable design that deploys to contact the vessel wall, capturing emboli and preventing their passage into the brain or other vital organs, with various configurations such as conical, cylindrical, or basket-like structures.

Benefits of technology

The integrated embolic filter effectively prevents emboli from reaching the brain and other organs during transcatheter procedures, enhancing patient safety and procedural outcomes by providing continuous protection without additional steps or access sites.

Abstract

To provide a catheter with a preferable integrated embolic protection device.SOLUTION: An artificial heart valve delivery catheter includes an embolic filter for providing integrated embolic protection in order to prevent embolus release into aorta, aortic arch or branched vessel, and other vascular systems during transvascular heart valve replacement procedure. Normally, the embolic filter will be attached fixedly or movably to a shaft of the delivery catheter proximal to the artificial heart valve.SELECTED DRAWING: Figure 10
