Abstract
An endoscopic tool for facilitating injection of fluid into a submucosal layer of tissue includes a first cannula, a suction source, a fluid lumen, and a second cannula. The first cannula has a suction surface disposed at a distal end, and defines a suction lumen. The suction source is coupled to the first cannula and creates a negative pressure within the suction lumen. The second cannula is disposed in a fluid lumen separate from the suction lumen, is adapted to be coupled to a source of fluid, and carries a needle at a distal end thereof. The tool draws the mucosal layer via the suction, which enlarges the submucosal layer, and injects a fluid into the enlarged portion of the submucosal layer via the needle, thereby creating a raised portion of tissue around the injection site.
