Abstract
An intraluminal protection system for capturing emboli in the blood stream comprises a tubular member having a lumen therethrough and an actuating member slideably mounted at the distal end of the tubular member and configured for longitudinal, telescopic movement with respect to the tubular member. A collapsible, self-expanding protection element (e.g. a filter, occluder, etc.) has a proximal end coupled to the tubular member and a distal end coupled to the actuating member such that when a fluid pressure is applied to the actuating member, the protection element collapses.
