4. Apparatus according to claim 1 wherein the elongated flexible element comprises a suture.
5. Apparatus according to claim 1 further comprising an inner face release liner releasably covering the adhesive on the inner face of the base.
6. Apparatus according to claim 1 wherein the adhesive applied to the inner face of the base is in the form of an adhesive sheet comprising an outer face and an inner face, and further wherein the outer face of the adhesive sheet is secured to the inner face of the base.
7. Apparatus according to claim 1 wherein the base comprises at least one notch.
8. Apparatus according to claim 7 wherein the at least one notch is aligned with the centerline of the at least one pillar.
9. Apparatus according to claim 7 wherein the at least one notch is not aligned with the centerline of the at least one pillar.
10. Apparatus according to claim 7 wherein the slot of the at least one lead-in is aligned with the at least one notch of the base.
11. Apparatus according to claim 1 wherein the at least one lead-in comprises a compressible material.
12. Apparatus according to claim 11 wherein the at least one lead-in further comprises a cap, and further wherein the cap comprises a non-compressible material.
13. Apparatus according to claim 1 wherein the at least one pillar further comprises a cap, and further wherein the cap comprises a non-compressible material.
14. Apparatus according to claim 1 wherein the at least one pillar has a height greater than the diameter of the at least one elongated flexible element.
15. Apparatus according to claim 1 wherein the plurality of pillars are spaced from one another by a distance sufficient to allow the elongated flexible element to be woven around the plurality of pillars in a serpentine fashion.
16. Apparatus according to claim 15 wherein the plurality of pillars are aligned with one another.
17. Apparatus according to claim 15 wherein the plurality of pillars are laterally offset from one another.
18. Apparatus according to claim 1 wherein the cover further comprises a plurality of openings, and further wherein the plurality of openings is configured to receive the plurality of cylindrical pillars when the inner face of the cover is positioned against the outer face of the base.
19. Apparatus according to claim 1 further comprising an inner face release liner releasably covering the adhesive on the inner face of the cover.
20. Apparatus according to claim 1 further comprising an outer face release liner releasably covering the adhesive on the outer face of the base.
21. Apparatus for securing an elongated flexible element to a patient, the apparatus comprising:
a base comprising a flat outer face and a flat inner face;
an adhesive applied to the flat inner face of the base;
a plurality of cylindrical pillars upstanding vertically from the flat outer face of the base, wherein each of the plurality of cylindrical pillars comprises a compressible foam material, and further wherein the plurality of cylindrical pillars are configured so that the elongated flexible element can be passed around the plurality of cylindrical pillars so as to provide a capstan effect;
an adhesive applied to the flat outer face of the base;
