A cannula comprising a hollow tube made of a biocompatible, thermoplastic polymer, memory shape material, tipped with an injection needle or an electrode at it distal end, assumes desired shapes as it distally emerges from a lumen or channel of an instrument such as an introducer or endoscope. The desires shapes include a curvature conforming to an inverse tangent function. The cannula may be supplied alone, with or without an injection needle or electrode, and in a sterile pouch, for use with a device of a user's choice that has a suitable lumen or channel to guide the cannula, of the cannula may be used without such an instrument. The injection needle can be shorter than conventional to thereby inject medication only or primarily in submucosa and can be sharpened only or mostly at it distal end while the remaining portion of a bevel is not sharp, to thereby reduce the size of an opening the needle makes in tissue and helps keep the medication from leaking out of the injection site.
