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 at one or more strut junctions , wherein the arcuate members 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 at one or more strut junctions , wherein the arcuate members are thinner than the frame strut width for providing axial flexibility for said stent frame. <EOS>
