Figure 1.

Three transmural columns of four bead sets each are implanted across the lateral wall using a depth-adjustable bead insertion trocar. To guide the trocar, a planar plexiglas template with three holes, spaced 10 mm apart, is sutured to the epicardial surface. First, three 0.7 mm diameter beads are inserted in each column, evenly spaced between the endo- and epicardial surfaces. Then, a fourth 1.7 mm diameter bead is sewn onto the epicardial surface above each column.
