摘要：
An endoscopic tool for facilitating injection of fluid into a submucosal layer of tissue includes a first cannula, a second cannula, and means for attaching the first cannula to a mucosal layer of tissue. The first cannula has a distal end and a proximal end opposite the distal end. The second cannula is adapted to be coupled to a source of fluid and carries a needle at a distal end thereof. The means for attaching the first cannula to the mucosal layer draws the mucosal layer, which enlarges the submucosal layer. Fluid is then injected into the enlarged portion of the submucosal layer via the needle, thereby creating a raised portion of tissue around the injection site.
