14. Using clinical judgment, advance the Needle into the targeted biopsy site until the Handle (B) rests against
the Safety Guide (F). In this “Hub-to-Hub” position, the Needle has advanced beyond the Distal Tip (L) of the 7 fr
Introducer.
Note: For best performance, as the Needle is advanced confirm that the Red Directional Arrow (H) on the 7 fr
Introducer is aligned in the same direction of the Red Cap (D) on the Handle (B) of the Needle to achieve Red-to-Red
Alignment. To achieve this, the Needle may be gently rotated. This orientation maintains proper alignment between
the direction of the Bend in the 7 fr Introducer and Specimen Notch (N) of the Needle. Maintain Red-to-Red alignment
during the last 5 cm of insertion.
15. While applying even pressure on the Needle to maintain its Hub-to-Hub position with the Safety Guide (F), gently
advance the Plunger (A) to the First Stop (Figure 10). This exposes the Specimen Notch (N).
16. Confirm location and exposure of Notch under visualization.
17. While maintaining Hub-to-Hub alignment, fire the Needle by applying additional pressure on the Plunger (A)
(Figure 11). You will feel and hear the firing of the Needle.
18. While maintaining the position of the 7fr Introducer, remove the Needle.
Caution: It is very important to inject contrast medium immediately following each firing of the needle to assess the
puncture and rule out capsular perforation and extravasation.
19. Remove the specimen from the Needle by pulling back on the Plunger (A) to the Charged Position (Figures 6 and
7) and gently pushing the Plunger (A) forward to the First Stop (Figure 10) to expose the Specimen Notch (N). Using
the Tissue Removal Swabs (Figure 3), the specimen may be safely and gently removed from the Specimen Notch
(Figure 12).
20. Process the specimen according to clinical protocols.
21. If desired, additional cores can be obtained by pulling Plunger (A) back to the charged position (Figure 7) and
proceeding as described above.
