Abstract: A biopsy needle set includes a biopsy needle with a tip that terminates distally in a laterally extending cutting edge that is spaced up from the bottom surface of the needle. A cradle, proximal to the needle, has a floor that is below a central axis of the needle and a row of teeth upwardly extending up from each lateral side of the floor up to about the central axis. Within each row, the teeth are distant from each other and the teeth of the two rows are staggered such that some cross-sections of the cradle include only one tooth and some none. The outer surface of the cradle bears against the inner surface of the cannula to keep the biopsy needle centered in the cannula and from bending to thereby better target tissue of interest for sampling.

Abstract: Biopsy tissue sample processing method and system configured to collect a tissue sample in a cradle at a distal portion of a biopsy needle. The cradle has an axially extending floor and two rows of teeth that extend up from sides of the cradle bottom. In each row, the teeth are axially spaced from each other. Dislodging the tissue sample from said cradle involves lightly touching, in a touch-and-go freehand motion of the cradle relative to the strip, an exposed side of the tissue sample in the cradle to a strip that has a surface configured to dislodge the tissue sample from the cradle without a need for an adhesive The cradle teeth protect the tissue sample from radial compression beyond a threshold in said touch-and-go motion and otherwise help maintain sample integrity.

Abstract: 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.

Abstract: A biopsy needle set that includes an outer cannula and a core collector that slides therein and includes a cradle that has a trough-shaped open space formed between a keel and two rows of teeth rising from lateral ends of the keel.
