4. Based on Tables 1 and 2, determine if the graft chosen requires the use of the Support Seal. If the graft requires the Support Seal, proceed to the
next step. If the graft does NOT require the Support Seal, proceed to step 7.
NOTE: Assembly of the Adapter and Support Seal (if applicable) may be better facilitated by performing the procedure over a flat sterile surface.
5. If using a graft from Table 2, insert the graft into the silicone sleeve end of the Support Seal. Some resistance may occur with the silicone sleeve.
However, the Support Seal should still be advanced onto the graft in these instances.
6. Advance the Support Seal down the majority of the graft length, stopping approximately 10cm from the end of the graft that will interface
with the Adapter.
7. Insert the tapered end of the Graft Expander into the graft end that will interface with the Adapter. Advance the graft as much as possible up to
the Graft Expander shoulder. Leave the Graft Expander in the end of the graft and prepare the Adapter for assembly.
NOTE: Inadequate expansion of the graft may make assembly of the graft and the Adapter more difficult. A back and forth twisting motion may
help to advance the graft.
8. Ensure the clamshells are open and centered around the base of the Adapter.
9. Grasp the graft near the shoulder of the Graft Expander and remove the Graft Expander from the graft.
10. Slide the expanded end of the graft onto the inflow end of the Adapter and advance the graft to the shoulder of the Adapter.
NOTES: If removal of the graft is difficult, it may help to gently pull the graft near the end of the Graft Expander.
Expansion can be repeated as needed using the Graft Expander.
ATTENTION: The clamshells cannot be opened once closed; do NOT close the clamshells prematurely.

11. If using the Support Seal, advance the silicone sleeve of the Support Seal up to the Adapter shoulder ensuring it is flush with both the graft
and the shoulder of the Adapter.
NOTE: Prior to closing the clamshells, verify that both the graft and the Support Seal (if applicable) are fully advanced to the shoulder of the
Adapter and that no portion of the Support Seal coil is under the clamshells.
12. Pinch the clamshells of the Adapter between the thumb and index fingers of both hands as tightly as possible.
