1. A biopsy device comprising:
an outer needle hub;
an outer needle coupled at a proximal end to the outer needle hub, the outer needle defining an outer diameter and an inner diameter, and including:
an outer needle tip at an opposite distal end;
a tissue slicing feature defined at said tip configured for cutting tissue;
an inner surface defining a lumen through said outer needle for receiving tissue therein, said inner surface including a countersink extending proximally from said tip to said inner diameter at a depth from said tip; and
at least one opening defined in said outer needle between said countersink and said proximal end;
an inner needle hub; and
an inner needle coupled at a proximal end to said inner needle hub, the inner needle including an inner needle tip at an opposite distal end, said inner needle coaxially disposed within the outer needle,
wherein said outer diameter has a dimension from 0.035-0.065 inches, said inner diameter has a dimension sized relative to the dimension of said outer diameter to provide a nominal wall thickness of 0.003-0.006 inches, and said depth of said countersink has a dimension of 0.08-0.10 inches.
