Abstract: A device and a method for delivering a solution to tissues and/or organs. The solution contains at least one solvent and at least one solute. The device includes at least one chamber which contains sodium 2-mercaptoethanesulfonate (Mesna) in powder form. The method includes dissolving the solute in the solvent inside the device. The resulting solution is delivered immediately to tissues and/or organs to facilitate dissection. A composition including Mesna and one or more dye which is used in a method of surgery, a kit including Mesna, and a method for visualization of a composition including Mesna which is applied to tissues. A method for producing a composition including Mesna for use in a method of surgery, a kit for obtaining a composition including Mesna for use in a method of surgery, a device for chemically assisted tissue dissection facilitated by Mesna, and a method of surgery using Mesna.
