1. A biopsy needle, comprising: an external tubular member having an internal lumen and a sharpened distal end; an internal member defining a central longitudinal axis and having a proximal portion connected to a distal portion, said distal portion including first and second spaced apart struts along a sample-containment space through which the axis extends and a tissue penetrating tip, said first strut having first and second edges adjoining a first surface facing the axis and said second strut having third and fourth edges adjoining a second surface facing the axis, said first and second surfaces forming a boundary of said sample-containment space, said sample-containment space having first and second radially-opposed lateral openings wherein the first lateral opening is bounded by the first and third longitudinal edges and the second lateral opening is bounded by the second and fourth longitudinal edges; and wherein said internal member is slidably positioned within said lumen of said external member between a first relative position in which said sample-containment space and lateral openings are at least partially extended from said external member, and a second relative position in which said sample-containment space and lateral openings are entirely within said lumen.
