1. A method of deploying an embolic protection device carried on an elongate support member at a location distal to a treatment site in a vessel of a patient comprising:
- providing a delivery catheter having a distal end and a lumen sized to slideably receive the elongate support member and embolic protection device, the delivery catheter having an elongate tubular shaft encircled by a sealing member, the sealing member being expandable from a delivery configuration to a deployed configuration;
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;
advancing the delivery catheter containing the embolic protection device through the lumen of the guide catheter until the sealing member extends from the distal end of the guide catheter;
occluding the flow of blood through the vessel with the sealing member of the delivery catheter in the deployed configuration;
after blood flow has been occluded advancing the embolic protection device to a location distal to the treatment site; and
deploying the embolic protection device.

Abstract
A device, method, and system of deploying an embolic protection device at a location distal to a treatment site in a vessel of a patient. A delivery catheter is encircled by a sealing member which is expandable from a delivery configuration to a deployed configuration. The device creates a seal to prevent the flow of blood during the treatment of vascular disease. A distal protection element is delivered by the delivery catheter and deployed to filter or remove embolic debris.
