ii. During sampling, when the cutter reaches the distal end of the sample aperture, it stops
moving momentarily and a tone sounds, indicating the biopsy cycle is complete. The
green LEDs on the holster interface illuminate to indicate the position of the cutter.
iii. Rotate the aperture rotation thumbwheel on the probe or aperture rotation knobs on the
holster to orient the sample aperture for the next sample acquisition.
c. Continue the biopsy procedure at Step 12 when ready to remove the specimen collection
chambers from the device.
Sample Interrupt
The biopsy cycle may be interrupted to avoid unnecessary injury.
a. To interrupt the biopsy cycle, push any button other than biopsy (or the arm/fire buttons for ST)
when the cutter is retracting from position 1 to 3 or when the cutter is advancing from 3 to 2.
When the biopsy cycle is interrupted, the cutter retracts to position 3 (Open).
b. The BIOPSY Indicator LED flashes blue.
c. To complete the interrupted biopsy cycle, push the BIOPSY button again.
Fluid Delivery
a. Ensure the sample aperture is in the OPEN position prior to delivering fluid.
NOTE: Ensure that the collection chamber is attached to probe before saline or fluid delivery.
NOTE: The sample collection chamber must be aligned with the sample tube during saline or
fluids delivery.
b. Attach a standard threaded syringe, with the fluid to be delivered, to the injection port.
c. Rotate the stopcock so the OFF indicator is pointing toward the tubing leading to the control
module.
d. Slowly inject fluid until it appears in the probe’s tubing line on the other side of the probe, near
where the pinch clip is.
NOTE: The fluid space of the axial vacuum line and inner lumen of the probe is approximately
9 cc for MST0809, 9 cc for MST0812, 10 cc for MST0815, 8 cc for MST1009, 8 cc for
MST1012, and 8 cc for MST1015.
e. Move the clamp (pinch clip) on the tubing line as close to the probe as possible and close it to
pinch the line.
f. Inject the necessary volume of fluids.
g. Release the clamp once fluids are delivered to the biopsy site.
h. Remove the syringe.
