Abstract:
1. An embolic protection device, comprising: an elongate tubular shaft having a proximal end, a distal end, and a lumen extending at least in part therethrough; a filter coupled to the shaft proximate the distal end, the filter having a distal mouth region, the filter including an extension portion of non-filtering material extending at least in part distally beyond the distal mouth region; and a plurality of pull cords coupled to the mouth portion, the pull cords forming a plurality of loop portions, and extending proximally along a longitudinal axis of the shaft such that altering the position of the pull cords shifts the filter between a first generally collapsed configuration and a second generally expanded configuration, wherein each of the loop portions includes a first end region disposed in a first cord lumen formed in a tube wall of the tubular shaft and a second end region disposed in a second cord lumen formed in the tube wall.
