Claim Text:
1. A biopsy needle for use in biopsies guided by a computed tomography (CT) imaging apparatus, comprising: a biopsy needle stylet having a solid shaft and being made of a first material selected from carbon fibre or plastic such that an appearance of the solid shaft generated by the CT imaging apparatus presents reduced imaging artifacts; a biopsy needle cannula having a hollow shaft configured to receive the solid shaft of the stylet, a proximal end and a distal end remote from the proximal end, the cannula being made of a second material selected from the group consisting of stainless steel, aluminum, nitinol, and Inconel, and the distal end being configured to pierce tissues of a patient; wherein the solid shaft of the stylet is positioned wholly inside the cannula and has a proximal end and an opposing distal end, the proximal end of the stylet being configured to fix the stylet to the cannula and the opposing distal end of the stylet being contiguous with the distal end of the cannula, and wherein the distal end of the cannula is effective to pierce tissues of a patient.
