Abstract

A variety of configurations of implant management devices are provided. The configurations provide different combinations of features for maintaining a location of an implant with respect to the device and managing filaments of the implant. One exemplary embodiment of a device includes a generally rectangular-shaped body having an implantable body retainer, an opening disposed a distance apart from the retainer and configured to receive a ligament graft therein, and a fold extending across the body and intersecting the opening. Folding one end of the body towards a bottom surface of the body along the fold can form a filament loop engaging region to hold in tension a filament loop extending from the implant. Additional filament(s) associated with the implant can be managed by various filament retention features. Methods for preparing a ligament graft for implantation by relying upon indicia formed on a surface of the device body are also provided.

First claim

What is claimed is:

1. A surgical implant management device, comprising:
a body having a first end, a second end, opposed walls extending between the first and second ends, a top side, and a bottom side, the body further comprising:
an implantable body retainer configured to retain an implantable body on the top side of the body;
an opening disposed more proximate to the second end than the first end;
a fold extending across the body, between the opposed walls, and intersecting the opening, the fold being configured such that the second end of the body is folded toward the bottom side of the body to form a filament loop engaging region along the fold, the filament loop engaging region being configured to receive one or more filament loops coupled to an implantable body retained by the implantable body retainer; and

a pair of opposed openings disposed on either side of a central longitudinal axis of the body that extends approximately parallel to the opposed walls, the pair of opposed openings being intersected by the fold, wherein a portion of the body disposed between the pair of opposed openings and the opening forms prongs of the filament loop engaging region for receiving one or more filament loops.

2. The device of claim 1 , wherein the opening is approximately symmetrical along a central longitudinal axis extending approximately parallel to the opposed walls, and is approximately symmetrical along the fold.

3. The device of claim 1 , further comprising a slit formed between the opening and the implantable body retainer, the slit being configured to receive the second end of the body that is folded toward the bottom side of the body.

4. The device of claim 1 , further comprising an alignment opening formed adjacent to the implantable body retainer, the alignment opening being configured to align the device on a graft preparation board.

5. The device of claim 1 , further comprising one or more filament retention features disposed between the first end and the implantable body retainer.

6. The device of claim 5 , wherein the one or more filament retention features comprise a pair of opposed tabs extending below the bottom side of the body, the tabs being configured to hold one or more filament limbs extending from an implantable body.

7. The device of claim 6 , further comprising a bore formed in the body and in communication with a slit formed in the first end, the bore being configured to receive the one or more filament limbs extending from the implantable body via the slit.

8. The device of claim 6 , wherein each of the opposed tabs includes a filament receiving region, and the pair of opposed tabs are configured such that the one or more filament limbs can be wrapped around the filament receiving regions of the opposed tabs.

9. The device of claim 5 , wherein the one or more filament retention features comprise a bore formed in the body and in communication with a slit formed in one of the opposed walls, the bore being configured to hold one or more filament limbs extending from an implantable body and slid into the bore via the slit.

10. The device of claim 5 , wherein the one or more filament retention features comprise a tab formed from two slits formed in one of the opposed walls, the tab being configured to hold one or more filament limbs extending from an implantable body.

11. The device of claim 1 , further comprising one or more indicia formed on the top side of the body between the implantable body retainer and the fold, the indicia being configured for use to mark an indicator on one or more filament loops coupled to an implantable body retained by the implantable body retainer, the indicator being indicative of a relevant depth for a surgical procedure.

12. The device of claim 1 , further comprising one or more indicia formed on the top side of the body between the fold and the second end, the indicia being configured for use to mark an indicator on a ligament graft associated with one or more filament loops coupled to an implantable body retained by the implantable body retainer, the indicator being indicative of a relevant depth for a surgical procedure.

13. A surgical implant management device, comprising:
a body having a first end, a second end, opposed walls extending between the first and second ends, a top side, and a bottom side, the body further comprising:
an implantable body retainer configured to retain an implantable body on the top side of the body;
an opening disposed more proximate to the second end than the first end;
a fold extending across the body, between the opposed walls, and intersecting the opening, the fold being configured such that the second end of the body is folded toward the bottom side of the body to form a filament loop engaging region along the fold, the filament loop engaging region being configured to receive one or more filament loops coupled to an implantable body retained by the implantable body retainer

one or more filament retention features disposed between the first end and the implantable body retainer;
an implantable body; and
one or more filament loops coupled to the implantable body, the one or more filament loops having at least one limb extending therefrom,
wherein the implantable body is retained by the implantable body retainer, the one or more filament loops are held in tension by the filament loop engaging region, and the at least one limb is held in tension by the one or more filament retention features.

14. The device of claim 13 , further comprising at least one of a shuttle filament and a toggle filament coupled to the implantable body, the at least one of the shuttle filament and the toggle filament being held in tension by the one or more filament retention features.

15. The device of claim 13 , further comprising a slit formed between the opening and the implantable body retainer, the slit being configured to receive the second end of the body that is folded toward the bottom side of the body.

16. The device of claim 13 , further comprising an alignment opening formed adjacent to the implantable body retainer, the alignment opening being configured to align the device on a graft preparation board.

17. The device of claim 13 , further comprising one or more filament retention features disposed between the first end and the implantable body retainer.

18. The device of claim 17 , wherein the one or more filament retention features comprise a pair of opposed tabs extending below the bottom side of the body, the tabs being configured to hold one or more filament limbs extending from an implantable body.

19. The device of claim 18 , wherein each of the opposed tabs includes a filament receiving region, and the pair of opposed tabs are configured such that the one or more filament limbs can be wrapped around the filament receiving regions of the opposed tabs.

20. The device of claim 13 , further comprising one or more indicia formed on the top side of the body between the implantable body retainer and the fold, the indicia being configured for use to mark an indicator on the one or more filament loops coupled to the implantable body retained by the implantable body retainer, the indicator being indicative of a relevant depth for a surgical procedure.

21. The device of claim 13 , further comprising one or more indicia formed on the top side of the body between the fold and the second end, the indicia being configured for use to mark an indicator on a ligament graft associated with one or more filament loops coupled to an im
