A catheter insertable and re-expandable growth stent for implantation in a neonate patient, comprising: an elongated stent frame with a plurality of frame struts each having a predetermined frame strut width and a predetermined strut thickness and extending continuously from a proximal end region of said stent frame to a distal end region of said stent frame, adjacent frame struts defining a predetermined number of intermediate frame cells and intersecting to form respective strut junctions with junction widths by which said elongated stent frame expands via a delivery catheter from an initial state with a diameter that is less than eight French (2.67 mm) for facilitating insertion via the delivery catheter into a selected lumen of the neonate patient to a first expanded state that has a first predetermined expanded size, shape, diameter, cross-section and/or other dimension that is greater than that of the initial state at implantation, said stent frame in the first expanded state defining an internal channel with a first cross-section, wherein the strut junctions further enable said stent frame to be re-expanded via subsequent introduction of a dilation catheter from the first expanded state to a second expanded state that has a second predetermined expanded size, shape, diameter, cross-section and/or other dimension that is greater than that of the first state as the patient grows, said stent frame in the second expanded state defining the internal channel with a second cross-section being larger than the first cross-section; wherein the elongated stent frame further comprises arcuate members (174, 176) at one or more strut junctions, wherein the arcuate members (174, 176) are thinner than the frame strut width for providing axial flexibility for said stent frame. an elongated stent frame with a plurality of frame struts each having a predetermined frame strut width and a predetermined strut thickness and extending continuously from a proximal end region of said stent frame to a distal end region of said stent frame, adjacent frame struts defining a predetermined number of intermediate frame cells and intersecting to form respective strut junctions with junction widths by which said elongated stent frame expands via a delivery catheter from an initial state with a diameter that is less than eight French (2.67 mm) for facilitating insertion via the delivery catheter into a selected lumen of the neonate patient to a first expanded state that has a first predetermined expanded size, shape, diameter, cross-section and/or other dimension that is greater than that of the initial state at implantation, said stent frame in the first expanded state defining an internal channel with a first cross-section, wherein the strut junctions further enable said stent frame to be re-expanded via subsequent introduction of a dilation catheter from the first expanded state to a second expanded state that has a second predetermined expanded size, shape, diameter, cross-section and/or other dimension that is greater than that of the first state as the patient grows, said stent frame in the second expanded state defining the internal channel with a second cross-section being larger than the first cross-section; wherein the elongated stent frame further comprises arcuate members (174, 176) at one or more strut junctions, wherein the arcuate members (174, 176) are thinner than the frame strut width for providing axial flexibility for said stent frame.
