Procedure for Models 2012-11, 2012-13, e2012-11, e2012-13
1. Expose the carotid artery and perform the arteriotomy in the usual manner.
2. Place the distal (internal carotid) end of the Shunt into the internal carotid artery.
3. Attach the 3 ml syringe to the white stopcock and SLOWLY inflate the internal carotid balloon with up to 0.25 ml of sterile saline.
(Figure A)
4. As inflation progresses, carefully observe back-bleeding from the internal carotid artery around the shunt. The back-bleeding
will diminish as the balloon expands. When the balloon is inflated sufficiently to occlude the artery, back-bleeding around
the shunt will stop, there will be a feeling of slight resistance to further inflation and/or there will be a slight distention of the
external safety balloon. This is the end-point: STOP INFLATION IMMEDIATELY AT THIS POINT. The external safety balloon should
not be inflated. (Figure B)
5. Close the white stopcock and slide the movable sleeve over the external safety balloon. This will prevent reflux from the internal
carotid balloon into the external safety balloon and prevent subsequent loss of vessel occlusion. (Figure E)
NOTE: The internal carotid balloon may accidentally become dislodged from its position by over inflation, handling of the artery, or
pulling on the Shunt. This may result in spontaneous decompression of the internal carotid balloon with reflux into the external safety
balloon and loss of occlusion in the artery. Placement of the sleeve or sheath over the external safety balloon prevents this potential
problem.
IMPORTANT: Should the internal carotid balloon be over inflated, causing the external safety balloon to inflate (Figure C), BOTH
balloons must be deflated. After both balloons have been deflated (Figure D), SLOWLY inflate the internal carotid artery balloon with
up to 0.25 ml of sterile saline without inflating the external safety balloon (Figure B).
6. Place the proximal (blue common carotid) end of the Shunt into the common carotid artery.
7. Attach a 3 ml syringe to the blue stopcock and slowly inflate the blue common carotid artery balloon with up to 1.5 ml of sterile
saline, close the blue stopcock.
8. Clamp across the Shunt lumen and remove the clamp on the common carotid artery. Slowly remove the clamp that is across the
Shunt and observe for air bubbles and/or atheromatous debris. If no bubbles or debris are seen, fully remove the clamp. Proceed
with the procedure.
9. When the endarterectomy is completed, deflate the balloons, remove the Shunt and close the arteriotomy in the usual manner.
