Abstract
An aspiration catheter has an elongate flexible tubular body that has a side wall and a distal tip. A helical coil is embedded in the side wall and extends from the proximal end of the catheter to a location offset proximally from the distal tip. A reinforcement fiber is longitudinally embedded in the side wall starting from a location offset proximally from the distal tip and extends proximally at least 10 cm. The distal tip has a shaped edge which assists the catheter tip in navigating past ledges in bifurcations.
