Patent ID: 7018343

Claim:
A biopsy needle for use in soft tissue sampling procedures comprising an elongate needle body having a longitudinal axis and sharp distal end having four facets, wherein each individual facet is substantially planar and said facets are arranged such that: each of a first pair of facets is positioned on the opposite side of the needle from the other, and both of said substantially planar surfaces of the first pair facets are oriented in a converging direction toward the distal-most end of the needle end; each of a second pair of facets is positioned such that each facet of said second pair is positioned between each of said first pair of facets, and both of the second pair of facets distally converge with one another so as to form a shared edge substantially in alignment with the longitudinal axis of the needle and said shared edge is positioned between distal-most points of each of said first pair of facets.
