摘要：
A cannula comprising a hollow tube made of a biocompatible, thermoplastic polymer, memory shape material, tipped with an injection needle 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 shape includes a curvature conforming to an inverse tangent function. The cannula may be supplied alone, with or without an injection needle, and in a sterile pouch, for use with a device of an user's choice that has a suitable lumen or channel to guide the cannula, of the cannula may be used without such an instrument.
