Abstract
This implantable microcatheter includes a hollow tube with a central lumen extending throughout the length of the tube from a proximal region to a distal region. The bending stiffness of the proximal region is greater than the bending stiffness of the distal region, and the tube has a transition region having a decreasing stiffness gradient from the proximal region to the distal region. The tube wall is free of shielding or armor at least in the distal region, and the catheter is made of biocompatible material(s) suitable for a permanent implantation in venous, arterial or lymphatic networks.
