HEARTSTRING III Proximal Seal System
7. Deliver the HEARTSTRING III Proximal Seal into the anastomotic site:
7.1 Insert the Delivery Device tip into the aortotomy site and actuate the Plunger to deploy the
HEARTSTRING III Proximal Seal (Figure 15). An audible click will confirm deployment.
NOTE: Blood within the Delivery Device is an indication of proper insertion.
PRECAUTION: Care should be taken while inserting the Delivery Device to reduce the risk of back-
walling the aorta.
7.2 Place a single finger over the Seal to anchor in place while slowly pulling the Delivery Device back
(Figure 16).
7.3 After the Delivery Device is removed, gently pull back the Proximal Seal Tension Spring until the
Tension Spring opens (Figure 17). If hemostasis is not adequate, use a blower mister, fine tip suction
or saline syringe to clear the field. If hemostatis is still not adequate, gently adjust the Tension Spring
to ensure that it is fully deployed. If still not adequate, use a finger for temporary hemostasis, remove
the HEARTSTRING III Proximal Seal and replace.
PRECAUTION: To prevent the risk of dislodging emboli, do not manipulate the aorta to adjust the
HEARTSTRING III Proximal Seal.
7.4 The Anchor Tab will weigh down the Seal Stem adjacent to the Anchor Tab (farthest from the
anastomosis), and provide a clear field for suturing. Verify that the aortotomy created by the punch or
Cutter is acceptable for anastomosis construction.
