Abstract
Method and apparatus for deploying a medical device in a vessel. The apparatus includes a cannula and a medical device, for example a blood filter. The cannula has a lumen that extends from a proximal end to a distal end, and a port on the outer surface of the cannula. The port has a passage extending distally. In use, the distal end of the cannula is inserted into a vessel. The medical device is inserted into the port. The medical device is advanced through the passage into the blood vessel. The medical device is deployed within the vessel. Finally, the medical device is removed from the vessel.
Claims8
A method of temporarily filtering embolic material from the blood in a blood vessel, said method comprising the steps of:
- providing a cannula having a first lumen which extends from a proximal end to a distal end of the cannula, and a second lumen which extends from a proximal end to the distal end of the cannula, said first lumen having a distal opening, wherein the two lumens are isolated from one another to the distal end of the cannula;
- introducing the distal end of the cannula into an aorta;
- inserting a filter into the second lumen;
- advancing the filter through the second lumen and through the distal opening into the aorta;
- and
- deploying the filter within the aorta.
