Abstract:
1. A method of performing an intravascular procedure at a treatment site in a vessel of a patient comprising: providing a sealing device having proximal and distal ends, a distal sealing portion and a proximal sealing portion and having a lumen extending therethrough; introducing a guide catheter into the vessel; advancing the guide catheter through the vessel until a distal end of the guide catheter is at a desired location proximal of the treatment site; introducing the sealing device into a lumen of the guide catheter; advancing the sealing device through the lumen of the guide catheter until the distal sealing portion extends from the distal end of the guide catheter; occluding the flow of blood through the vessel with the sealing device; after blood flow has been occluded advancing a distal protection device through the lumens of the guide catheter and the sealing device and through the vessel to a location distal to the treatment site; deploying the distal protection device; after the distal protection device has been deployed withdrawing the distal sealing portion of the sealing device into the guide catheter to thereby re-establish the antegrade flow of blood though the vessel at the treatment site; advancing a vascular treatment device through the guide catheter to the treatment site and performing the intravascular procedure with the treatment device while blood is flowing antegrade through the vessel at the treatment site.
