Abstract
Systems and methods of delivering a patch to a target site of a patient are described herein. The patch may comprise a biomaterial such as chitosan or extracellular matrix and may be biocompatible and/or bioresorbable. The system may include an endoscope, a patch, and one of an instrument or a cap, the patch being coupled to the respective instrument or cap and detachable therefrom. Methods of delivering the patch to the target site may include introducing an endoscope into a gastrointestinal tract of a patient, e.g., the patch being in a folded or crimped configuration, navigating a distal end of the endoscope proximate a target site; and applying the patch to the target site while releasing the patch from the endoscope.
