A biodegradable balloon-expandable stent, comprising: a biodegradable metal alloy scaffold comprising a plurality of metal struts; and a biodegradable polymer coating at least partially covering the metal struts, wherein the biodegradable metal alloy scaffold comprises a magnesium alloy, an iron alloy, a zinc alloy, or combination thereof, wherein coated struts have a cross-sectional width between 100-600 μm, wherein the polymer coating has a thickness between 10-100 μm, and wherein the metal scaffold comprises a cylinder-shaped stent body containing a plurality of axially arranged rows of struts encircling a central lumen in which each row of struts comprises struts inter-connected to form a wave-pattern with alternating peaks and troughs, each peak having a tip and each trough having a bottom, wherein the rows of struts form one or more row sections comprising at least one row of struts and a plurality of non-flex connectors connecting adjacent rows of struts within each row section, each of the plurality of non-flex connectors comprising a first end and a second end, whereby the first end is attached to a tip of a peak in a first row of struts, and the second end is attached to a tip of a peak in a second row of struts, whereby the first and second rows of struts are within the same row section and are adjacent to each other such that no non-flex connector is present in a row section containing only one row of struts, wherein the rows of struts further comprise a plurality of flex connectors connecting adjacent row sections, each of the plurality of flex connectors comprising a first end and a second end, whereby the first end is attached to a bottom of a first trough in an edge row of struts of a first row section, the first trough having a first trough amplitude, whereby the second end is attached to a bottom of a second trough in an edge row of struts of a second row section, and the second trough having a second trough amplitude, whereby the first row section is adjacent to said second row section, and wherein the stent body is capable of being twisted clockwise or counter-clockwise from one end of said stent body by one-fourth of a turn, or more, without causing deformation of any struts, non-flex connectors or flex-connectors in the stent body. a biodegradable metal alloy scaffold comprising a plurality of metal struts; and a biodegradable polymer coating at least partially covering the metal struts, wherein the biodegradable metal alloy scaffold comprises a magnesium alloy, an iron alloy, a zinc alloy, or combination thereof, wherein coated struts have a cross-sectional width between 100-600 μm, wherein the polymer coating has a thickness between 10-100 μm, and wherein the metal scaffold comprises a cylinder-shaped stent body containing a plurality of axially arranged rows of struts encircling a central lumen in which each row of struts comprises struts inter-connected to form a wave-pattern with alternating peaks and troughs, each peak having a tip and each trough having a bottom, wherein the rows of struts form one or more row sections comprising at least one row of struts and a plurality of non-flex connectors connecting adjacent rows of struts within each row section, each of the plurality of non-flex connectors comprising a first end and a second end, whereby the first end is attached to a tip of a peak in a first row of struts, and the second end is attached to a tip of a peak in a second row of struts, whereby the first and second rows of struts are within the same row section and are adjacent to each other such that no non-flex connector is present in a row section containing only one row of struts, wherein the rows of struts further comprise a plurality of flex connectors connecting adjacent row sections, each of the plurality of flex connectors comprising a first end and a second end, whereby the first end is attached to a bottom of a first trough in an edge row of struts of a first row section, the first trough having a first trough amplitude, whereby the second end is attached to a bottom of a second trough in an edge row of struts of a second row section, and the second trough having a second trough amplitude, whereby the first row section is adjacent to said second row section, and wherein the stent body is capable of being twisted clockwise or counter-clockwise from one end of said stent body by one-fourth of a turn, or more, without causing deformation of any struts, non-flex connectors or flex-connectors in the stent body.
