1. A mold for a radially expandable stent, comprising:
- a mold member comprising a mold bore including an axial section with a radial cross section that oscillates between a proximal end and a distal end of the mold bore, the axial section being configured to mold a stent mounted on a delivery system to have an oscillating radial cross section along an axial section of the stent, wherein the axial section of the stent improves flexibility of the mounted stent during delivery,wherein an inner surface along the axial section of the mold bore has a wave-like profile with crests alternating with troughs, andwherein a height variation between the crests and the troughs is between 0.001 to about 0.005 inches.

11. A mold for a radially expandable stent, comprising:
a mold member comprising a mold bore comprising an inner surface along the axis of the mold bore having a wave-like profile, the wave-like profile comprising a first trough, and first crest, a second trough, a second crest, and third trough, a third crest, and a fourth trough extending from the distal to the proximal end of the mold bore, wherein a distance between the second and the third trough is greater than a distance between both the distance between the first and second trough and the distance between the third and fourth trough. - View Dependent Claims (12)
