Abstract:
Method of endoscopically injecting a defined amount of at least one fluid, in particular a solution, suspension or emulsion, into a tissue of a hollow organ, a body cavity or an artificial cavity in a human or animal body, in which a specified amount of fluid is expelled out of an end of a tube or a nozzle with hydraulic parameters i.e. pressure, rate of pressure increase, duration and/or velocity are adjusted to specified values for providing an energy of said fluid such that, after traveling a distance between the end of the tube or the nozzle and the tissue in substantially free flight, the fluid penetrates into the tissue and remains within said tissue wherein to inject relatively large amounts of fluid, a plurality of substantially equal-sized minimal quantities or fluid quanta is injected, wherein the fluid is injected at an angle of about 30Â° to 60Â° with respect to the tissue or to its surface.
