Method of deflecting emboli from the cerebral circulation
First Claim
Patent Images
1. A method of deflecting emboli flowing within a main vessel from entering first and second side branch vessels, comprising the steps of:
- advancing an expandable emboli deflection device through the first side branch vessel and into the main vessel, the emboli deflection device attached to a distal end of an elongate shaft; and
manipulating the deflection device such that it expands to cover the ostia of each of the first and second side branch vessels, wherein manipulating the deflection device comprises applying traction to the elongate shaft to create a seal between the deflection device and the main vessel wall over the ostia of the first and second side branch vessels;
wherein the deflection device permits blood flow from the main vessel into each of the first and second side branch vessels, but deflects emboli from entering the first and second side branch vessels.

Abstract
Disclosed is a blood debris deflector, for preventing embolization during a surgical procedure, and methods for insertion and removal of the deflector. The method can include the steps of advancing an embolic deflection device through a first side branch vessel and into the main vessel, manipulating the deflection device such that it covers the opening to a second side branch vessel, and inverting the deflection device to remove the device from a patient.
