Abstract:
1. A medical device for use in a body lumen, the device comprising: a first catheter shaft having a proximal end region, a distal end region, and a fluid lumen connecting the proximal end region and the distal end region; a second catheter shaft slidably disposed within the first catheter shaft; a guidewire slidably disposed in a lumen of the second catheter shaft; a filter coupled to the guidewire; a balloon coupled to the distal end region of the first catheter shaft; a stent disposed adjacent the second catheter shaft, wherein the balloon and the first catheter shaft are configured to stop fluid outside of the first catheter shaft proximal to the balloon from flowing distally past the distal region of the shaft when the balloon is expanded; wherein the stent is self-expanding and configured to be deployed from a position between the distal end of the first catheter shaft and the filter; and wherein the first catheter shaft defines a perfusion lumen configured for the passage of perfusing fluid supplied at the proximal end region therethrough so as to flush embolic debris into the filter.
