3. The nest and tub arrangement according to claim 2 , wherein a bottommost one of the at least one nest is at least partially supported by the bottom ledge surface of the tub.
4. The nest and tub arrangement according to claim 2 , wherein the top portion is delineated by a bottom ledge surface and a top lid flange.
5. The nest and tub arrangement according to claim 4 , wherein the plurality of guide elements extend along a sidewall of the tub between the bottom ledge surface and the top lid flange.
6. The nest and tub arrangement according to claim 1 , wherein each of the plurality of rigid guide ribs comprises a contact surface, and wherein the contact surface of each of the plurality of rigid guide ribs comprises an angle of inclination between the bottom ledge surface and the top lid flange.
7. The nest and tub arrangement according to claim 6 , wherein the angle of inclination of the contact surface is 1.0° or less.
8. The nest and tub arrangement according to claim 1 , wherein each of the plurality of rigid guide ribs is formed as a semi-cylindrical guide rib.
9. The nest and tub arrangement according to claim 1 , wherein the plurality of guiding elements comprise rigid shafts that extend from a bottom surface of the tub, and further wherein the at least one nest comprises a plurality of shaft openings formed therein and sized and positioned so as to receive the rigid shafts.
10. The nest and tub arrangement according to claim 1 , wherein the at least one nest further comprises at least one finger opening formed therein.
11. The nest and tub arrangement according to claim 1 , wherein the at least one nest comprises a plurality of nests and further wherein the plurality of nests are configured to be stackable atop one another within the tub.
12. A nest and tub arrangement for the storage of medical device components, comprising:
a tub comprising a plurality of guide elements extending from at least one surface of the tub and into the interior of the tub, wherein the plurality of guide elements comprises a plurality of flexible ribs and a plurality of rigid guide ribs; and
at least one nest comprising a plurality of receptacles for the storage of a plurality of medical device components therein, wherein the at least one nest is sized and configured for placement within the tub such that the plurality of guide elements align and removably retain the at least one nest within the tub,
wherein the at least one nest further comprises a plurality of opening portions formed thereon, and wherein each of the plurality of opening portions are semi-circular in shape and are positioned and sized to substantially conform to an outer contour of the plurality of rigid guide ribs,
wherein each of the plurality of flexible ribs comprises a proximal end portion coupled to the tub and a distal end portion decoupled from the tub.
