A core collector is shaped as a crescent in cross-section and has lateral sides formed into axially extending rows of axially spaced teeth. The arc angle of the crescent shape is sufficient to keep the core collector radially centered in a cannula by having the crescent's lateral sides bear against the inside of the cannula. The set of a core collector and cannula can be used in a known biopsy system to replace the known cannula and core collector of can be used in a new core biopsy instrument.

Biopsy system with a core collector that remains radially centered in an outer cannula while severing a tissue sample

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.
