THROMBOEMBOLIC PROTECTION DEVICE

摘要

Disclosed herein are systems and methods for protecting a subject from embolisms during TAVR percutaneous valve procedures. Various embodiments include an intravascular embolism protection device that includes an elongated, compliant wire frame made from a material having a shape-memory function, and a mesh sleeve coupled to the compliant wire frame, the mesh material having a pore size selected to allow blood to pass therethrough while retaining potential emboli. In some embodiments, the embolism protection device has a collapsed state wherein device fits within the lumen of a deployment/retrieval catheter and an expanded state wherein the embolism protection device expands to span the width of the aorta and the distance between the aortic valve and the puncture site in the femoral artery.

1. An intravascular embolism protection device comprising:
an elongated, compliant wire frame comprising a material having a shape-memory function; an elongated mesh sleeve having an outer surface and an inner lumen, the elongated, compliant, wire frame being disposed within the inner lumen, the mesh sleeve having a pore size selected to allow blood to pass therethrough while restricting the passage of potential emboli; wherein the embolism protection device has a collapsed state wherein the embolism protection device fits within the lumen of a catheter, and an expanded state wherein the embolism protection device forms a hollow tube that is sized to span the width of an aorta and extend from an aortic valve to a puncture site in a femoral artery.
