Endovascular device for entrapment of participate matter and method for use
A method for filtering particulate matter from a blood vessel in a patient, including inserting a device into the blood vessel, the device including at least an outer structure capable of insertion into the blood vessel; and an inner filter anchored to the outer structure, the inner filter having a one-way valve though which a medical instrument may be passed.
1. An intra-vascular device to prevent emboli in an aortic arch from entering all side branches of said aortic arch, said device comprising:
a self-expanding filter element with a distal opening and a proximal end, said self-expanding filter element has a tapered shape towards said proximal end; and said self-expanding filter element is capable of insertion into said aortic arch to cover all said side branches, whereby said self-expanding filter element forms a trap for said emboli entering said self-expanding filter element distally;
said proximal end of said self-expanding filter element sized to receive a catheter, and
wherein said proximal end is a valve formed from a material of said self-expanding filter element.
2. The device of claim 1 , wherein said self-expanding filter element is made from a blood filtering material.
3. The device of claim 2 wherein said material is a mesh sized to trap emboli while permitting blood flow.
4. The device of claim 2 , wherein said blood filtering material includes lateral thin wires to maintain physical form and strength.
5. The device of claim 1 , wherein said self-expanding filter element is capable of anchorage to the wall of the aorta.
6. The device of claim 1 , wherein said self-expanding filter element is reinforced at said distal opening to remain open.
7. The device of claim 6 , wherein said reinforcement is a thread.
8. The device of claim 1 , wherein said self-expanding filter element is capable of expanding to the size and shape of a vessel.
9. The device of claim 1 , wherein said self-expanding filter element is constructed from a metallic material.
10. The device of claim 1 , wherein said device is configured to be passable through a femoral artery.
