Abstract
A method of making a high flexibility distal zone on a neurovascular catheter is provided. The method includes the steps of dip coating a removable mandrel to form a tubular inner layer on the mandrel, coating the tubular inner layer with a tie layer, applying a helical coil to the outside of the tie layer, positioning a plurality of tubular segments, heating the tubular segments to form the high flexibility distal zone on the neurovascular catheter; and removing the mandrel.
