7.8.1 When the Twelve Chambers of the Tissue Filter Contain Cores
The Brevera breast biopsy system with CorLumina imaging technology can acquire more
than twelve biopsy cores per tissue filter. For these cases, when each of the twelve
chambers in the tissue filter contains a biopsy core, the Brevera breast biopsy system
presents two options: to continue using the existing filter or to continue with a new filter.
Continue with the Existing Tissue Filter
1. Release the footswitch.
2. Press down on the footswitch and hold it in the depressed position throughout the
biopsy procedure.
3. Continue to acquire biopsy specimens and to view their x-rays on the Imaging
display.
4. At the end of the tissue acquisition or after the twenty-fourth core specimen,
whichever comes first, continue with the instructions for Lavage and Aspirate on page
82.
Continue with a New Tissue Filter
1. Release the footswitch.
2. Open the tissue filter drawer.
3. Remove the tissue filter cover from the tissue filter assembly.
4. Place a dry tissue filter cap on the tissue filter. (The tissue filter cap is provided with
the biopsy needle.)
5. Remove the used filter from the tissue filter assembly and the tissue filter drawer.
6. Place the used tissue filter in a specimen jar on the surface of the formalin.
Note
The specimen jar should have a minimum inner diameter of 6.1 cm (2.4 inches) and a
minimum height of 5.7 cm (2.25 inches) in order to fit a Brevera tissue filter.
7. Slowly submerge the tissue filter to allow the formalin to enter the chambers and air
to escape. (Do not allow the tissue filter to float on top of the formalin.) Prepare the
specimens for pathology per facility policy.
8. Install a new tissue filter.
9. Replace the cover on the tissue filter assembly, and close the tissue filter drawer. The
system is ready when the indicators on the Imaging display return to green.
10. Select Yes on the Imaging display when asked if a new filter was inserted into the
drawer.
11. Depress the footswitch.
12. Continue to acquire biopsy specimens and to view their x-rays on the Imaging
display.
13. At the end of tissue acquisition or after the twenty-fourth core specimen, whichever
comes first, continue with the instructions for Lavage and Aspirate on page 82.
