Abstract
A catheter having a distal tip comprising two sections of different hardness, and a method of making the same, is herein disclosed. The first section of the two sections is distal to the second section of the two sections and the second section is comprised of a material that is harder than the material of the first section. Additionally, the distal tip is bonded to a catheter shaft and the material of the catheter shaft is harder than the material of the first and second sections. The material of the catheter shaft, first section, and second section can comprise polyether block amide, with each section and the catheter shaft having different properties.
