A catheter comprising a soft tip segment (5), a transition segment (11), and a shaft segment (3). The soft tip segment (5) has at least two ungular sections (6, 7) removed from the proximal end. The distal end of the transition segment (11) is bonded to the proximal end of the soft tip (5) segment. The transition segment (11) is comprised of materials having substantially higher tensile strength than the soft tip (5) segment. The distal end of the shaft (3) is bonded to the proximal end of the transition segment (11). The distal end of the shaft (3) has at least two ungular sections (2, 4) removed. |
