A stent having a nominally deployed state, an axially extended state, and an axially compressed state, the stent having a length, in the axially extended state the length being at least 20% greater than in the nominally deployed state; wherein the stent comprises a plurality of strut columns comprising a first strut column and a second strut column, wherein the plurality of strut columns comprise columnar struts interconnected by alternating peaks and troughs, and connector columns, the connector columns comprising connector struts extending between adjacent strut columns (20a, 20b) in a peak-to-trough configuration, wherein: the connector struts comprise a first axial segment, a second axial segment, and a circumferential segment, the first axial segment and the second axial segment extending from the circumferential segment, the circumferential segment disposed between the first and second axial segments (34, 36), the circumferential segment extending in a circumferential direction across at least one trough of the first strut column and at least one peak of the second strut column; the first axial segment and the circumferential segment defining a first angle (40, 40', 40") therebetween and the second axial segment and the circumferential segment defining a second angle (42, 42', 42") therebetween, characterised in that when the stent is in the nominally deployed state the first angle is between 90 and 115 degrees and the second angle is between 90 degrees and 115 degrees; when the stent is in the axially extended state the first angle is between 125 and 180 degrees and the second angle is between 125 and 180 degrees; and when the stent is in the axially compressed state, the first angle (40") and second angle (42") are less than when the stent is in the nominally deployed state, wherein the stent is configured to axially extend to the axially extended state without significantly altering a deployed diameter of the stent. a plurality of strut columns comprising a first strut column and a second strut column, wherein the plurality of strut columns comprise columnar struts interconnected by alternating peaks and troughs, and connector columns, the connector columns comprising connector struts extending between adjacent strut columns (20a, 20b) in a peak-to-trough configuration, wherein: the connector struts comprise a first axial segment, a second axial segment, and a circumferential segment, the first axial segment and the second axial segment extending from the circumferential segment, the circumferential segment disposed between the first and second axial segments (34, 36), the circumferential segment extending in a circumferential direction across at least one trough of the first strut column and at least one peak of the second strut column; the first axial segment and the circumferential segment defining a first angle (40, 40', 40") therebetween and the second axial segment and the circumferential segment defining a second angle (42, 42', 42") therebetween, characterised in that when the stent is in the nominally deployed state the first angle is between 90 and 115 degrees and the second angle is between 90 degrees and 115 degrees; when the stent is in the axially extended state the first angle is between 125 and 180 degrees and the second angle is between 125 and 180 degrees; and when the stent is in the axially compressed state, the first angle (40") and second angle (42") are less than when the stent is in the nominally deployed state, wherein the stent is configured to axially extend to the axially extended state without significantly altering a deployed diameter of the stent. the connector struts comprise a first axial segment, a second axial segment, and a circumferential segment, the first axial segment and the second axial segment extending from the circumferential segment, the circumferential segment disposed between the first and second axial segments (34, 36), the circumferential segment extending in a circumferential direction across at least one trough of the first strut column and at least one peak of the second strut column; the first axial segment and the circumferential segment defining a first angle (40, 40', 40") therebetween and the second axial segment and the circumferential segment defining a second angle (42, 42', 42") therebetween, characterised in that when the stent is in the nominally deployed state the first angle is between 90 and 115 degrees and the second angle is between 90 degrees and 115 degrees; when the stent is in the axially extended state the first angle is between 125 and 180 degrees and the second angle is between 125 and 180 degrees; and when the stent is in the axially compressed state, the first angle (40") and second angle (42") are less than when the stent is in the nominally deployed state, wherein the stent is configured to axially extend to the axially extended state without significantly altering a deployed diameter of the stent.
