HEARTSTRING III Proximal Seal System
8. With the HEARTSTRING III Proximal Seal deployed in position, perform the anastomosis:
8.1 Suture using an inside-out suturing technique on the aorta. Ensure that the HEARTSTRING III
Proximal Seal is maintained in a position between the first and last suture bites of the anastomosis.
8.2 The horizontal distance between the HEARTSTRING III Proximal Seal and the tail should be
large enough to facilitate HEARTSTRING III Proximal Seal removal. Fully complete the entire
anastomosis, but do not tie down the suture.
WARNING: Care should be taken when suturing to avoid inadvertent stitching or dislodging of the
HEARTSTRING III Proximal Seal or wrapping the suture around the Seal Stem. If this occurs, back the
needle up and confirm adequate hemostasis. If inadequate hemostasis, apply partial occlusion clamp,
remove the HEARTSTRING III Proximal Seal and complete the anastomosis using an aortic clamp.
9. The following technique should be used to remove the HEARTSTRING III Proximal Seal after completion
of anastomosis:
9.1 Loosen the two stitches immediately adjacent to the Seal Stem (one stitch per side). The suture should
be loosened between the graft and the aortic tissue, forming a loop of free suture between the graft and
aorta approximately 1 cm in diameter, or approximately 3 cm in length (Figure 18).

9.2 Have an assistant hold the untied suture ends during HEARTSTRING III Proximal Seal removal.
9.3 While securing the Seal Stem, cut one end of the Tether and remove the Tension Spring with
remaining tether (Figure 19).
WARNING: To prevent any risk of HEARTSTRING III Proximal Seal embolization, do not release
the Seal Stem until the HEARTSTRING III Proximal Seal is fully removed.
