An endoscopic endocap for excising a target portion of a native tissue from a remaining portion of the native tissue during a surgical procedure includes an annular main body. The main body has a proximal end and an oppositely disposed distal end. The distal end includes an extension that protrudes longitudinally beyond a remaining portion of the distal end. An outer surface of the distal end, and an inner surface of the main body, extend longitudinally between the proximal and distal ends. The inner surface defines at least one lumen with an opening terminating at the terminal portion of the distal end. At least one excisor is disposed on the extension with the excisor laterally spaced from the outer surface of the annular main body. The excisor remains stationary with respect to the lumen during use of the excisor to excize the target portion of the native tissue.
