Abstract:
A biopsy needle assembly includes a mandrel within a cannula, the needle assembly is fired into a target tissue to obtain a tissue sample using a force source imparting movement to the needle assembly. The mandrel and cannula design, and force source characteristics minimize needle deflection, and allow the needle assembly to excise extended length tissue samples. The mandrel forms tissue retention ridges within a tissue sample region to reduce fragmentation of the tissue sample.

Claim (Index 1):
An apparatus, comprising:\n a cannula, comprising:\n a body extending between a first end and a second end, the body having a first side and an opposite second side; and \n a leading edge formed by the first end, the leading edge extending along a first plane, the first plane extending between the first side and second side, the first plane forming a leading edge angle between the intersection of the first side and the first plane, wherein the leading edge angle is between about 12 degrees and about 20 degrees; \n a mandrel, comprising:\n a body extending between a first end and a second end along a central longitudinal axis; \n a notch formed by the body, the notch forming a bed extending between the first end and the second end; \n a first sample region formed by the bed, the first sample region, comprising:\n a first plurality of ridges, wherein each of the first plurality of ridges comprises: \n a flank extending from the bed toward the mandrel body second end, the flank terminating at a crest; and\n a concave slope descending from the crest; \n \n a second sample region formed by the bed, the second sample region comprising:\n a second plurality of ridges, wherein each of the second plurality of ridges comprises: \n a flank extending from the bed toward the mandrel body second end, the flank terminating in a crest; and \n a concave slope descending from the crest; \n a deck disposed between the first plurality of ridges and the second plurality of ridges.
