Abstract

The present disclosure relates to implantable medical devices which include grip-members and methods of reinforcing tissue with such devices.

Claims

1. An implantable medical device for supporting tissue comprising:

a first surgical mesh having a planar configuration and including a first top surface including a plurality of first filamentary grip-members and a first bottom surface including a plurality of second filamentary grip-members;

a second surgical mesh having a planar configuration and including a second top surface including a plurality of third filamentary grip-members and a second bottom surface including a plurality of fourth filamentary grip-members, wherein the first bottom surface of the first surgical mesh is attached to the second top surface of the second surgical mesh via the second and third filamentary grip-members; and

a third surgical mesh having a planar configuration and including a third top surface including a plurality of fifth filamentary grip-members and a third bottom surface including a plurality of sixth filamentary grip-members, wherein the first and third surgical mesh are vertically staggered and the second and third surgical mesh are horizontally aligned in the same plane.

2. The implantable medical device of claim 1, wherein the first surgical mesh is smaller in area than the second surgical mesh.

3. The implantable medical device of claim 1, wherein the first and second surgical mesh are staggered.

4. The implantable medical device of claim 3, wherein a first portion of the second filamentary grip-members and a first portion of the third filamentary grip-members connect the first bottom surface to the second top surface, and a second portion of the third filamentary grip-members attach a second portion of the second top surface to tissue.

5. The implantable medical device of claim 1, wherein the first filamentary grip-members connect the first top surface to tissue.

6. The implantable medical device of claim 1, wherein a second portion of the second filamentary grip-members and a first portion of the fifth filamentary grip-members interlock to connect a second portion of the first bottom surface to a first portion of the third top surface.

7. The implantable medical device of claim 6, wherein a second portion of the fifth filamentary grip-members connects a second portion of the third top surface to tissue.

8. The implantable medical device of claim 7, wherein the second surgical mesh further includes second side filamentary grip-members positioned along an outer edge of the second surgical mesh, wherein the second side filamentary grip-members connect the second surgical mesh to at least one of the third surgical mesh or tissue.

9. The implantable medical device of claim 8, wherein the third surgical mesh further includes third side filamentary grip-members positioned along an outer edge of the third surgical mesh wherein the third side filamentary grip-members connect the third surgical mesh to at least one of the second surgical mesh or tissue.

10. The implantable medical device of claim 9, wherein the second side filamentary grip-members of the second surgical mesh connect to the third side filamentary grip-members of the third surgical mesh.

11. The implantable medical device of claim 1, wherein the first, second, and third surgical mesh each consist essentially of a plurality of filaments.

12. An implantable medical device for supporting tissue comprising:

a first substrate having a first top surface including a plurality of first grip-members and a first bottom surface including a plurality of second grip-members; and

a second substrate having a second top surface including a plurality of third grip-members, a second bottom surface including a plurality of fourth grip-members and a second side surface between the second top surface and the second bottom surface, wherein the first bottom surface of the first substrate is attached to the second top surface of the second substrate via the second and third grip-members

a third substrate having a third top surface including a plurality of fifth grip-members and a third bottom surface including a plurality of sixth grip-members, wherein the third top surface of the third substrate is attached to at least one of the first or second substrates, wherein the second substrate further includes second side grip-members positioned along the second side surface of the second substrate, wherein the second side grip-members connect the second side surface of the second substrate to at least one of the third substrate or tissue.

13. The implantable medical device of claim 12, wherein the first substrate is smaller in area than the second substrate.

14. The implantable medical device of claim 12, wherein the first and at least one of the second or third substrates are staggered.

15. The implantable medical device of claim 14, wherein the second and third substrates are horizontally aligned in the same plane.

16. The implantable medical device of claim 15, wherein a first portion of the second grip-members and a first portion of the third grip-members connect the first bottom surface to the second top surface, and a second portion of the third grip-members attach a second portion of the second top surface to tissue.

17. The implantable medical device of claim 12, wherein a second portion of the second grip-members and a first portion of the fifth grip-members interlock to connect a second portion of the first bottom surface to a first portion of the third top surface, and a second portion of the fifth grip-members connects a second portion of the third top surface to tissue.

18. The implantable medical device of claim 12, wherein the third substrate further includes third side grip-members positioned along an outer edge of the third substrate wherein the third side grip-members connect the third substrate to at least one of the second substrate or tissue.

19. The implantable medical device of claim 18, wherein the second side grip-members of the second substrate connect to the third side grip-members of the third substrate.

20. The implantable medical device of claim 12, wherein the first, second, and third substrates each have a planar configuration.
