Biodegradable waveguides and their uses with devices, such as medical devices, are described. In one embodiment, an optically transmissive fibrous structure comprising biodegradable fiber waveguides may be disposed on a surface of a bandage. The bandage in combination with the optically transmissive fibrous structure may allow for simultaneously monitoring and covering an injured area of a patient. In one embodiment, the fiber waveguides may be provided as multi-channel/multi-core biodegradable fiber waveguides for transmitting light to and from a patient tissue. In some implementations, the bandage may include hydrogel-based biodegradable fiber waveguides that may deliver therapeutics to an injured patient area.
