Patent ID: 7527636

Claim:
An intraluminal guidewire and distal protection device, comprising: an elongate hypotube having a proximal end and a distal end and having a fluid lumen therethrough, the hypotube having an outer diameter dimensioned to enable a therapeutic catheter to be advanced onto and along the guidewire; a distal protection device secured to the hypotube proximate said distal end, the protection device being deployable to an expanded configuration and being contractable about the hypotube after being deployed; a slave actuating member coupled to the distal protection device and slidably mounted proximate said distal end of the hypotube for longitudinal movement with respect to the hypotube; and a master actuating member having a portion disposed within the proximal portion of the lumen for longitudinal movement within said hypotube, whereby when the lumen is filled with fluid said master actuating member is hydraulically coupled to said slave actuating member.
