Abstract: Several embodiments disclosed herein relate to apparatus and methods for treating a diverticulum. In some examples, disclosed is a device for inverting a diverticulum including a device body, a pushing apparatus that includes a rod and a blunt end, and a user actuated structure that provides control of the pushing apparatus. Also disclosed is a method for inverting a diverticulum. The method can include positioning a device along an outer wall of a colon at a diverticulum, inverting the outer surface of the diverticulum with the distal end of the device, and then actuating the user actuated structure such that the pushing apparatus interacts with the diverticulum to further invert the diverticulum.
