Abstract
Instruments, systems and methods are provided for performing submucosal medical procedures in a desired area of the digestive tract using endoscopy. Instruments include a safe access needle injection instrument, a submucosal tunneling instrument, a submucosal dissection instrument, a mucosal resection device. Systems include a combination of one or more of such instruments with or without injectable agents. Embodiments of various methods for performing the procedures are also provided.
Claims5
A method of resecting a target area of mucosal tissue, comprising:
- identifying the target area of mucosal tissue for resection;
- elevating a submucosal layer adjacent the target area by injecting a fluid into the submucosal layer;
- inserting a submucosal tunneling instrument into the elevated submucosal layer;
- operating said submucosal tunneling instrument to create an elongate tunnel in the submucosal layer;
- positioning a submucosal dissecting instrument within the elongate tunnel formed by said tunneling instrument;
- operating said submucosal dissecting instrument within the elongate tunnel to thereby dissect an area having a diameter larger than a diameter of said elongate tunnel and encompassing said target area;
- positioning a tissue resection tool within the dissected area adjacent a boundary between the dissected submucosal layer and an undissected submucosal layer;
- and
- operating said tissue resection tool to resect said target area of mucosal tissue.
