Medical devices and medical assemblies that have a lubricant disposed on an inner surface (e.g., balloons to be inflated within a cavity of a patient) are disclosed, along with related methods of use and manufacture. Such devices or assemblies may be passed through an elongate channel (e.g., a catheter channel or the working channel of an endoscope) and deployed distal of the elongate channel to adopt an expanded configuration. The devices or assemblies may then be compacted as they are withdrawn into the elongate channel after deployment. Some medical devices and assemblies comprising a lubricant on an inner surface of a balloon body may be more readily withdrawn into the elongate channel than embodiments that lack such a lubricant.
