Preferably, the sheath is removed by everting it over itself during the delivery process. By orienting the pleats along the length of the sheath, preferably 10 helically around the sheath, the sheath undergoes a predictable enlargement during deployment so as to relive friction of the everted sheath sliding along itself during deployment. This allows the sheath to be removed with less tension than previous everting sheath constructions is and assures more accurate device placement in a patient. 3642672_1 (GHMatters) P84555.AU.1 29/08121/8 22 F126 12 362 20 24 28 30 14 FIG. 1 -8 38 1 34 32 16 322 36 3 20 FIG. 2
