Abstract
Systems and methods provide intraluminal delivery of a bandage structure within a body lumen or hollow body organ, e.g., for treating an injured gastrointestinal tract or an esophageal hemorrhage in a non-invasive way using endoscopic visualization. The systems and methods can be sized and configured to apply a chitosan bandage structure within a body lumen or hollow body organ, to take advantage of the mucoadhesive, antimicrobial, hemostatic, and potential accelerated wound healing properties of the chitosan material.
