Abstract

The invention includes a catheter having an elongate main body having a proximal section and a distal section. The elongate main body further includes a plurality of stiffening members disposed along the length of the elongate main body. The plurality of stiffening members includes a first stiffening member and a second stiffening member. The first and second stiffening members can be disposed in an overlapping and spaced relationship. Alternatively, the second stiffening member can be disposed distal to the first stiffening member such that a gap is defined between the stiffening members.
