Abstract:
A temporary filter device comprising:an elongate proximal guidewire shaft having a distal end; a relatively short distal guidewire shaft having a proximal end and being disposed distal to and coaxially aligned with the proximal shaft; a generally tubular filter mounted coaxially about the proximal and distal guidewire shafts, the filter having a tapered distal end fixed adjacent the proximal end of the distal shaft and a tapered proximal end fixed adjacent the distal end of the proximal shaft, wherein relative longitudinal movement between the distal and proximal ends of the filter accompanies a transformation of the filter between a collapsed configuration and an open configuration; an actuator slidably disposed along the proximal guidewire shaft; and at least one link slidably disposed through at least one opening near the filter proximal end and connecting the actuator to the distal end of the filter.
