1. An elongate medical device having a device longitudinal axis and a device distal region, the elongate medical device comprising:
a balloon at the device distal region and having a balloon longitudinal axis, the balloon comprising:
a balloon proximal portion;
a balloon distal portion that is distal of the balloon proximal portion; and
a balloon inflatable portion with a first length that is configured to transition from a deflated state to an inflated state, wherein the balloon inflatable portion includes a portion of the balloon proximal portion and a portion of the balloon distal portion, and wherein, in the inflated state, the balloon is symmetrical about the balloon longitudinal axis;
wherein the balloon proximal portion has a second length and a first profile shape, the first profile shape including a first concave shape with a first profile radius; and
wherein the balloon distal portion has a third length and a second profile shape, the second profile shape including a i) second concave shape with a second profile radius greater than the first profile radius and ii) a substantially concave tissue contacting surface, and wherein the second length of the balloon proximal portion is less than the third length of the balloon distal portion.
