Bioabsorbable radially self-expanding stent (21) with one or more supplemental apparatus or methods for achieving the desired final resting diameter of the stent (21) by imparting memory into the bioabsorbable material components. A balloon (107) is used to increase the radial expansion force of the stent (21). The one or more supplemental apparatus include substituting within the stent body (43) one or more particularly rigid threads (30) relative to the other threads (22,26), forming one or more of the helical threads (32,34) of two side-by-side threads (32,34) with one of the threads comprised of standard material and the other comprised of a more rigid material, attaching one or more bands (40) to the sent body (43), and weaving circular or oval bands (41) into the threads forming the wall of the stent shaped and positioned to resist axially elongation of the stent (21). |
