A stent and associated method for implanting a stent within a body conduit are provided. According to one embodiment, the stent includes a plurality of annular segments arranged peripherally along a longitudinal axis to define opposing free ends, wherein each annular segment includes a plurality of interconnected segment struts. The stent also includes a plurality of connector struts each extending along the longitudinal axis between, and connecting, adjacent annular segments, wherein each connector strut includes an axial section and a compensating section. In addition, at least a portion of each of the segment struts, axial sections, and compensating sections is curved.

a plurality of annular segments arranged peripherally along a longitudinal axis to define opposing free ends, each annular segment comprising a plurality of interconnected segment struts; and
a plurality of connector struts each extending along the longitudinal axis between, and connecting, adjacent annular segments, each connector strut comprising an axial section and a compensating section, wherein at least a portion of each of the segment struts, axial sections, and compensating sections is curved, wherein each of the compensating sections comprises a V-shaped section having a pair of curved inclined sections, wherein each of the segment struts and axial sections continuously curve along their respective lengths, wherein a pair of segment struts is configured to conform to each axial section along their respective lengths in a contracted state, and wherein a plurality of adjacent segment struts are adjoined to one another via a transition section, the transition section being directly attached to an adjacent compensating section.
2. The stent according to claim 1 , wherein each of the segment struts and axial sections is curved in a wave shape.
3. The stent according to claim 1 , wherein each of the segment struts extends obliquely with respect to the longitudinal axis.
4. The stent according to claim 1 , wherein each of the compensating sections comprises a pair of arms extending parallel to one another and from the pair of curved inclined sections to define a closed end.
5. The stent according to claim 4 , wherein each of the closed ends extend in a same peripheral direction.
6. The stent according to claim 1 , further comprising a plurality of head ends extending from respective transition sections at one or more of the free ends.
7. The stent according to claim 1 , wherein a width of at least a portion of each of the connector struts is less than a width of each of the segments struts.
8. The stent according to claim 7 , wherein a width of each axial section is less than a width of each segment strut.
9. The stent according to claim 1 , wherein each of the segment struts widens from a middle area to its respective ends.
10. The stent according to claim 1 , wherein each annular segment comprises a plurality of segment struts defining a plurality of peaks and valleys each extending in a same axial direction along the longitudinal axis, and wherein each of the plurality of connector struts extends between respective peaks of the segment struts.
11. A stent comprising:
a plurality of annular segments arranged peripherally along a longitudinal axis to define opposing free ends, each annular segment comprising a plurality of interconnected segment struts; and
a plurality of connector struts each extending along the longitudinal axis between, and connecting, adjacent annular segments, the plurality of the connector struts comprising:
