6-6
ii. Rotate the probe/holster assembly to orient the sample aperture for the next sample
acquisition.
NOTE: Manual rotation of the specimen collection chambers is necessary for more than 25
tissue samples in a single large chamber.
b. Continue the biopsy procedure at Step 8 removal of 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 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 biopsy cycle, push the BIOPSY button again.
Delivering Fluid to Biopsy Site
During the procedure, while the probe is in position, the stopcock on the axial vacuum line can be used to
deliver fluids to the biopsy site.
a. Ensure the sample aperture is in the OPEN position prior to deliver 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 the
pinch clip.
NOTE: The fluid space of the axial vacuum line and inner lumen of the EX probe is
approximately 9 cc for MHEX08(S).
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 required volume of fluids.
g. Release the clamp after the fluids are delivered to the biopsy site.
h. Remove the syringe.
