1. A medical device comprising:
- a catheter shaft including a proximal region and a distal region; and
a balloon disposed about a distal region of the catheter shaft, wherein the balloon includes a body region and only a single pre-formed bulge region that protrudes radially outward from the body region when the balloon is expanded without a stent thereon, wherein the single pre-formed bulge region is positioned at a location between a proximal end and a distal end of the body region, wherein the single pre-formed bulge region is formed at a predetermined location around a circumference of the body region and extends around less than the entire circumference of the body region.
