WARNING: Take care to avoid scrapping of the needle tip against the protective sleeve and injury
while removing the protective sleeve.
3. Introduce the probe into the percutaneous site through the skin incision.
NOTE: To introduce the probe from the percutaneous site, ensure the sample aperture is closed off,
either by a biopsy site identifier applicator or a fully closed cutter.
NOTE: Ensure that sample management system chambers are attached to the MHEX08S probe
[with or without sleeve] before beginning sample acquisition.
4. With the system in the READY state, orient the sample aperture to the desired position, then press
the BIOPSY button on the active input device (holster, remote footswitch, or remote keypad) to
acquire a tissue sample.
NOTE: Pressing and releasing the BIOPSY button produces a single tissue sample, while pressing
and holding the button produces continuous sampling when the user is holding down the
BIOPSY button. If continuous sampling is desired, refer to Other Instructions, Continuous
Sampling.
Biopsy Function Description
• The biopsy cycle proceeds automatically.
• As the inner cutter cannula of the probe is retracted, the previous sample moves from the
viewing window to the aligned chamber in the sample management system.
• After the inner cutter cannula of the probe is retracted, lateral and axial vacuum are
applied, tissue is drawn into the sample aperture, and the hollow inner cutter rotates and
translates forward, cutting tissue.
• When the cutter reaches the distal end of the sample aperture, it stops moving and uses
vacuum and a small amount of saline to transport the sample to the sample viewing
window.
NOTE: When the vacuum canister is full of fluid, the overfill protection system is
activated and the vacuum stops operating. Replace the vacuum canister.
• The BIOPSY Indicator LED continuously flashes blue, and the motor is audible during the
sampling and tissue collection process.
• At the end of the biopsy cycle, a tone sounds, the vacuum turns off and the Biopsy
Indicator LED illuminates solid blue.
