A device for placement within a blood vessel to maintain or enhance blood flow through the blood vessel, the device comprising multiple, balloon-expandable, bioresorbable, vascular stent elements configured to be implanted in the blood vessel as a multi-element stent , with the multiple stent elements not touching one another; wherein the stent elements comprise a first set of closed cells and a second set of closed cells , wherein the first set of closed cells have a different shape or size than the second set of closed cells ; wherein the first set of closed cells have a repeating longitudinally aligned pattern and a repeating circumferentially aligned pattern, wherein the second set of closed cells have a repeating longitudinally aligned pattern and a repeating circumferentially aligned pattern, wherein the first set of closed cells and the second set of closed cells are circumferentially offset, and wherein the first set of closed cells and the second set of closed cells have a helically aligned alternating pattern; wherein the first set of closed cells are larger cells having a first opening dimension and the second set of closed cells are smaller diamond-shaped closed cells having a second opening dimension smaller than the first opening dimension ; wherein each of the larger closed cells is formed by at least one wider strut and at least one thinner strut, wherein the wider strut has a first width and the thinner strut has a second width less than the first width ; wherein the wider struts are between adjacent longitudinally aligned larger closed cells , and wherein the thinner struts are between adjacent circumferentially aligned larger closed cells ; wherein each of the larger closed cells is further formed by at least one intermediate-width strut, wherein the intermediate-width strut has a third width smaller than the first width and larger than the second width ; and wherein the intermediate-width struts are between adjacent helically aligned larger closed cells and smaller diamond-shaped closed cells . wherein the stent elements comprise a first set of closed cells and a second set of closed cells , wherein the first set of closed cells have a different shape or size than the second set of closed cells ; wherein the first set of closed cells have a repeating longitudinally aligned pattern and a repeating circumferentially aligned pattern, wherein the second set of closed cells have a repeating longitudinally aligned pattern and a repeating circumferentially aligned pattern, wherein the first set of closed cells and the second set of closed cells are circumferentially offset, and wherein the first set of closed cells and the second set of closed cells have a helically aligned alternating pattern; wherein the first set of closed cells are larger cells having a first opening dimension and the second set of closed cells are smaller diamond-shaped closed cells having a second opening dimension smaller than the first opening dimension ; wherein each of the larger closed cells is formed by at least one wider strut and at least one thinner strut, wherein the wider strut has a first width and the thinner strut has a second width less than the first width ; wherein the wider struts are between adjacent longitudinally aligned larger closed cells , and wherein the thinner struts are between adjacent circumferentially aligned larger closed cells ; wherein each of the larger closed cells is further formed by at least one intermediate-width strut, wherein the intermediate-width strut has a third width smaller than the first width and larger than the second width ; and wherein the intermediate-width struts are between adjacent helically aligned larger closed cells and smaller diamond-shaped closed cells . <EOS>
