wherein the wall comprises a plurality of longitudinal wall segments, each longitudinal wall segment slidably connected to two other longitudinal wall segments; wherein the longitudinal body has a compressed configuration with a first transverse cross-sectional area and an expanded configuration with a second transverse cross- sectional area, wherein the first transverse cross-sectional area is less than the second transverse cross sectional area.

1 1. The expandable dilator of claim 10, wherein the longitudinal wall segments have a greater amount of overlap between adjacent longitudinal wall segments in the compressed configuration than in the expanded configuration.

12. The expandable dilator of claim 10, wherein the first transverse cross-sectional area and the second transverse cross-sectional area are rectilinear.

13. The expandable dilator of claim 10, wherein the transverse first cross-sectional area and the second transverse cross-sectional area are triangular.

14. The expandable dilator of claim 10, wherein the first transverse cross-sectional area and the second transverse cross-sectional area are curvilinear.

15. A delivery sleeve for delivering an implant to a delivery site, the delivery sleeve comprising:

a longitudinal body having a distal end, a proximal end and a wall with an inner surface that defines a passage extending through the longitudinal body, the passage configured to receive the implant;

wherein the longitudinal body includes a flexible tapered distal portion having a plurality of longitudinal slits that divide the tapered distal portion into at least two expandable blade portions, the expandable blade portions configured to rotate outwards upon the application of force on the inner surface of the expandable blade portions.

16. The delivery sleeve of claim 15, further comprising an inner tube that is slidably disposed within the passage of the longitudinal body, wherein the inner tube is configured to apply force on the inner surface of the expandable blade portions.

17. The delivery sleeve of claim 15, wherein each longitudinal slit terminates at a stress relief cutout.

18. The delivery sleeve of claim 15, wherein the longitudinal body has a rectilinear transverse cross-section.

19. The delivery sleeve of claim 15, wherein the longitudinal body has a triangular transverse cross-section.

20. The delivery sleeve of claim 15, further comprising an adjusting sleeve that is controllably disposed within the passage of the longitudinal body to extend the length of the passage.

21. A dilator system, the system comprising:
