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 catheter can also include a balloon formed from a tubular member having a recess defined in a portion of its surface. A tapered or thinned balloon is formed from a process by which material is removed from a tubular member prior to formation of the balloon.
