Encoded cinching mechanism for use with an implant delivery sleeve

1. A delivery sleeve, comprising:

an enclosure having a first portion, an orifice, and a throat disposed between the first portion and the orifice; and

a cinching mechanism disposed about the throat,

in which the cinching mechanism comprises a plurality of demarcations each of which are indicative of a sized opening of the throat.

2. The delivery sleeve of claim 1 , in which the plurality of demarcations comprise symbols.

3. The delivery sleeve of claim 2 , in which the symbols comprise lines.

4. The delivery sleeve of claim 1 , in which the plurality of demarcations comprise different colors or patterns, each color or pattern of which is indicative of the sized opening of the throat.

5. The delivery sleeve of claim 1 , in which the plurality of demarcations comprise successive numberings.

6. The delivery sleeve of claim 1 , in which the plurality of demarcations comprise alphanumerical symbols.

7. The delivery sleeve of claim 1 , in which the plurality of demarcations comprise tactile structures.

8. The delivery sleeve of claim 1 , in which the enclosure comprises s a structure that aligns with any of the plurality of demarcations, and in which the structure in combination with any of the plurality of demarcations is indicative of the sized opening of the throat.

9. The delivery sleeve of claim 8 , in which the structure comprises slits or eyelets or a fastener.

10. The delivery sleeve of claim 1 , in which the cinching mechanism includes a string, filament, tape, strap, band, cable tie, ribbon, or a combination thereof.

11. The delivery sleeve of claim 10 , in which the plurality of demarcations are disposed at a first end of the cinching mechanism, and the cinching mechanism further comprises a fastener disposed at an end opposite end of the cinching mechanism.

12. The delivery sleeve of claim 11 , in which the fastener includes a hook-and-loop fastener, a cord lock, a ratchet, an elastic ring, a magnetic ring, or a combination thereof.

13. The delivery sleeve of claim 11 , in which the fastener comprises a releasable fastener.

14. A cinching mechanism, comprising:

a flexible structure comprising a first end and a second end;

a plurality of demarcations at the first end of the flexible structure, the plurality of demarcations indicative of a sized opening of a delivery implant sleeve; and

a fastening mechanism at the second end of the flexible structure.

15. The cinching mechanism sleeve of claim 14 , in which the plurality of demarcations comprise symbols, different colors, successive numberings, tactile configurations, or alphanumerical symbols.

16. The cinching mechanism of claim 14 , in which the flexible structure includes a string, filament, tape, strap, band, cable tie, ribbon, or a combination thereof.

17. The cinching mechanism of claim 14 , in which the fastening mechanism includes a hook-and-loop fastener, a cord lock, a ratchet, an elastic ring, a magnetic ring, or a combination thereof.

18. The cinching mechanism of claim 17 , in which the fastening mechanism comprises a releasable fastener.

19. A method of using a delivery sleeve, comprising:

providing the delivery sleeve, the delivery sleeve comprising,

an enclosure having a throat with an orifice, and

a structure on the delivery sleeve, and

a cinching mechanism having a plurality of demarcations, the cinching mechanism disposed about the throat in a loose configuration such that the throat and the orifice are in an open configuration;

inserting an implant having a size into the enclosure through the orifice and the throat; and

changing the configuration of the throat to a predetermined size opening of the throat corresponding to the size of the implant by aligning one of the plurality of demarcations with the structure.
