CAUTION: Do not insert the cannula forcefully through the cervical os into the uterus. Forceful
movements may cause uterine perforation or damage to the cervix, pelvic organs or blood vessels.
Remain alert to signs that may indicate perforation throughout the procedure and stop suction
immediately if they appear.
• Attach the cannula (with adapter if required) to the prepared aspirator
(vacuum established) by grasping the cannula firmly at the base
with one hand, holding it steady. Make sure that the cannula does
not move forward into the uterus as you attach the aspirator. With
the other hand, hold the aspirator by the valve body. Gently rotate
the aspirator and push cannula base in firmly, twisting slightly if
necessary. Do not grasp the cylinder as this can twist the MVA Plus
liner.
– Alternatively, attach the aspirator to the cannula before inserting
the cannula through the cervical os.
Note: The Ipas 3mm cannula and the flexible Karman cannula size
4 -10 require an adapter to be added to the cannulae before it is
inserted into the Ipas MVA Plus aspirator. No adapter is required
when using sizes 3 - 6mm with the Ipas Single-Valve aspirator.
• Release the button(s) on the aspirator to transfer the vacuum through the cannula into the uterus.
Blood, tissue and bubbles should begin to flow through the cannula into the aspirator.
• For uterine evacuation, evacuate the contents of the uterus by rotating the cannula 180 degrees in each
direction while using a gentle in-and-out motion.
Note: When performing endometrial biopsy, movement of the cannula inside the uterus will vary
according to the purpose of the biopsy. To take a sample, aspirate tissue by moving the cannula gently
back and forth along the anterior uterine wall, then rotate the cannula and take a sample from the
posterior uterine wall in the same manner. A small amount of tissue is sufficient for diagnosis in most
cases.
• When performing uterine evacuation, if the aspirator fills up so that suction stops, depress the
valve button(s) and disconnect the cannula from the aspirator. Leave the cannula inserted through the
cervical os. Either replace the aspirator or empty its contents and then reattach it to the cannula. When
using the Ipas MVA Plus, stabilize the cannula by grasping it at the base with one hand and hold it
steady. With the other hand, hold the aspirator by the valve body. Rotate the aspirator and gently
separate it from the cannula.
• If the cannula becomes clogged, ease it back toward, but not through, the external os of the cervix.
This movement will often unclog the cannula. If it does not, depress the valve button(s) and remove
the cannula from the uterus, taking care to prevent contamination. Alternatively, remove the cannula
without depressing the button(s). Remove the tissue with sterile forceps. Reinsert the cannula and
continue the procedure, if necessary.
CAUTION: Never try to unclog the cannula by pushing the plunger back into the cylinder.
• For uterine evacuation, when the uterus is empty, withdraw the cannula from the uterus and depress
the valve button(s). Disconnect the cannula from the aspirator. Alternatively, withdraw the cannula
and aspirator together without depressing the button(s). The signs listed below indicate that the uterus
is empty:
– red or pink foam without tissue is seen passing through the cannula; and
– a gritty sensation is felt as the cannula passes over the surface of the evacuated uterus; and
– the uterus contracts around (grips) the cannula; and
– the patient notes pain as the uterus contracts.
