Abstract

There is disclosed a blood debris deflector for preventing embolization during a surgical procedure, and methods for insertion and removal of the deflector.

Claims

1. A blood debris deflector for protecting against embolization comprising a blood flow permeable covering extending over the ostia of the innominate and left common carotid arteries.

2. The deflector of claim 1 wherein the deflector is capable of being inserted and placed through a catheter in an artery of the arm of a patient.

3. The deflector of claim 2 wherein the artery is the brachial artery of a patient.

4. The deflector of claim 1 wherein the deflector is capable of being inserted and placed through a catheter in the femoral artery of a patient.

5. The deflector of claim 1 wherein prior to withdrawal, the deflector may be inverted, trapping debris.

6. The deflector or claim 1 wherein the periphery is adapted to seal against the walls of the aortic arch.

7. The deflector of claim 6 wherein the periphery is supported by an elastomeric member.

8. The deflector of claim 6 wherein the periphery is supported by a nitinol wire.

9. A method of employing a debris deflector to cover the ostia of the innominate and left common carotid arteries comprising the steps of:

a. Accessing the circulation through percutaneous insertion of a catheter into the right brachial artery;

b. Guiding a wire through the right brachial artery into the aortic arch via the innominate artery;

c. Placing a collapsed deflector in a sheath over the wire, and guiding the deflector into the aortic arch;

d. Withdrawing the sheath from the deflector, exposing the deflector to aortic bloodflow, and expanding the deflector; and

e. Pulling the deflector back to cover the ostia of the innominate and left common carotid arteries.

10. The method of claim 9 further comprising the steps of:

f. Performing a surgical procedure;

g. Inverting the deflector into a sheath; and

h. Withdrawing the inverted deflector from the patient.

11. A method of employing a debris deflector to cover the ostia of the innominate and left common carotid arteries comprising the steps of:

a. Accessing the circulation through percutaneous insertion of a catheter into the femoral artery;

b. Guiding a wire through the femoral artery into the innominate artery;

c. Placing a collapsed deflector in a sheath over the wire, and guiding the deflector into the aortic arch;

d. Withdrawing the sheath from the deflector, exposing the deflector to aortic bloodflow, and expanding the deflector; and

e. Pushing the deflector to cover the ostia of the innominate and left common carotid arteries.

12. The method of claim 11 further comprising the steps of:

f. Performing a surgical procedure;

g. Inverting the deflector into a sheath; and

h. Withdrawing the inverted deflector from the patient.
