1. A device, comprising:
a balloon configured for inflation with a light-diffusing fluid and configured, upon inflation, to expand a body lumen within which it is positioned; and
a flexible light-emitting device attached to the balloon having a light-emitting side facing distally and radially inward toward the fluid so that, during a medical procedure, light emitted from the light-emitting side is diffused by the fluid and directed proximally to illuminate a treatment area within the body lumen proximal to the balloon.
