Preparing the Sealed Outflow Graft
Characteristics that identify and distinguish a HeartMate III sealed Outflow Graft from a
HeartMate II sealed Outflow Graft are as follows:
• The product packaging label indicates it is a HeartMate III Sealed Outflow Graft.
• A purple screw ring that attaches to the Pump (the HeartMate II has a blue screw ring).
Figure 5.9 HeartMate III Sealed Outflow Graft
Prepare a HeartMate III sealed Outflow Graft for implantation, in a sterile environment, using a
strict sterile technique. Complete the following procedure:
1. Remove the Bend Relief from the graft.
2. Inspect the interior of the graft and remove any debris.
3. Attach the open thread protector.
4. Place the Bend Relief over the graft, with the metal end sliding toward the screw ring.
The Bend Relief should be disengaged for the de-airing procedure. Only the Vascular Graft
is intended to be cut or clamped, not the Outflow Graft Bend Relief.
WARNING !
• The sealed Outflow Graft should not be implanted in patients who exhibit sensitivity to
materials of bovine origin.
• A sealed Outflow Graft ( Figure 5.9 ) does not require pre-clotting. Attempting to pre-clot a
sealed Outflow Graft may disrupt or destroy the sealant and lead to profuse bleeding after
implantation.
