Abstract

A mesh fixation system is disclosed including a plurality of elongate members and each elongate member includes a plurality of longitudinally extending support members. Each support member is connected to an adjacent support member by a plurality of connecting members and the elongate member defines at least one opening extending therethrough between adjacent support members and adjacent connecting members. The mesh fixation system further includes a plurality of legs extending from each support member. The plurality of legs is adapted for insertion through a mesh and into a body tissue to secure the mesh to the body tissue.

Claims

1. A mesh fixation device comprising:

a plurality of elongate members monolithically formed together, each elongate member comprising;

a plurality of longitudinally extending support members, each support member connected to an adjacent support member by a plurality of connecting members, the elongate member defining at least one opening extending therethrough between adjacent support members and adjacent connecting members;

an attachment joint coupling a first elongate member to a second elongate member, the first and second elongate members separable at the attachment joint upon the application of a force to the attachment joint; and

a plurality of legs extending from each support member, the plurality of legs adapted for insertion through a mesh and into a body tissue to secure the mesh to the body tissue.

2. A mesh fixation device according to claim 1, wherein each of the legs includes at least one fixation member adapted to limit withdrawal of the leg from the body tissue after insertion therein.

3. A mesh fixation device according to claim 1, wherein the elongate members are formed by injection molding.

4. A mesh fixation device according to claim 1, wherein the elongate members are formed of a polymer.

5. A mesh fixation device according to claim 1, wherein the elongate members are formed of a lactomer based system.

6. A mesh fixation device according to claim 1, wherein the support members are disposed in substantially parallel alignment.

7. A mesh fixation device according to claim 1, wherein the connecting members are disposed in substantially parallel alignment.

8. A mesh fixation device according to claim 1, wherein the connecting members are disposed in transverse alignment to the support members.

9. A mesh fixation device according to claim 1, wherein each support member includes at least four legs.

10. A mesh fixation device according to claim 1, wherein the attachment joint includes a first portion attached to the first elongate member, a second portion attached to the second elongate member and an intermediate portion between the first portion and the second portion, the first and second elongate members separable at the intermediate portion upon the application of force to the attachment joint.

11. A mesh fixation device according to claim 10, wherein the intermediate portion defines a smaller cross-section than the first and second portions of the attachment joint.

12. A mesh fixation device according to claim 11, wherein the attachment joint defines a taper from the first and second portions to the intermediate portion.

13. A mesh fixation device according to claim 10, wherein the intermediate portion includes at least one of a perforation and scoring.

14. A mesh fixation device according to claim 10, wherein the first portion remains attached to the first elongate member and the second portion remains attached to the second elongate member when the elongate members separate at the intermediate portion.

15. A mesh fixation device according to claim 1, wherein each of the elongate members is configured for insertion through a 5 mm opening.

16. A mesh fixation system comprising:

a mesh; and

a plurality of elongate members monolithically formed together, each elongate member including;

a plurality of longitudinally extending support members, each support member connected to an adjacent support member by a plurality of connecting members, the elongate member defining at least one opening extending therethrough between adjacent support members and adjacent connecting members;

an attachment joint coupling a first elongate member to a second elongate member, the first and second elongate members separable at the attachment joint upon the application of a force to the attachment joint; and

a plurality of legs extending from each support member, the plurality of legs adapted for insertion through the mesh and into a body tissue to secure the mesh to the body tissue.

17. A mesh fixation system according to claim 16, wherein four elongate members are included.

18. A mesh fixation system according to claim 16, wherein each leg includes at least one fixation member adapted to limit withdrawal of the leg from the body tissue after insertion therein.

19. A mesh fixation system according to claim 16, wherein the elongate members are removably attached together and adapted to be separated before insertion into a body opening.

20. A mesh fixation system according to claim 16, wherein each support member includes at least four legs.
