Abstract

A hernia repair device, which is implantable in a patient'"'"'s body, includes first and second layers cooperating with one another so as to form an implantable patch for repairing a hernia defect. The first layer is made from a textile material which is absorbable in a patient'"'"'s body, while the second layer is made from a non-absorbable textile material. When the patch is implanted in a patient'"'"'s body, the non-absorbable second layer remains permanently implanted, while the absorbable first layer is dissolved.

Claims

1. A hernia repair device implantable in a patient'"'"'s body, comprising a first layer;

a second layer cooperating with said first layer so as to form an implantable patch for repairing a hernia defect, at least one portion of said first layer being made from a textile material which is absorbable in a patient'"'"'s body, and at least one portion of said second layer being made from a non-absorbable textile material; and

a third layer, said first and third layers being attached to one another so as to form a pouch for receiving said second layer therein, whereby when said patch is implanted in a patient'"'"'s body, said at least one portion of said second layer remains permanently implanted, while said at least one portion of said first layer is absorbed.

2. The hernia repair device of claim 1, further comprising expanding means for expanding said patch into its planar configuration, said expanding means being made from a second absorbable material so as to be absorbed when said patch is implanted in a patient'"'"'s body.

3. The hernia repair device of claim 2, wherein said expanding means a spring located in said pouch.

4. The hernia repair device of claim 1, wherein said third layer cooperates with said first layer and said second layer to form said patch.

5. The hernia repair device of claim 1, wherein said second layer is contained in said pouch without being attached to any one of said first and third layers.

6. A hernia repair device comprising a first layer;

a second layer cooperating with said first layer so as to form an implantable patch for repairing a hernia defect, at least one portion of said first layer being made from a textile material which is absorbable in a patient'"'"'s body, and at least one portion of said second layer being made from a non-absorbable textile material; and

a third layer, said first and third layers being attached to one another so as to form a pouch for receiving said second layer therein, at least one portion of said third layer being made from said absorbable textile material, whereby when said patch is implanted in a patient'"'"'s body, said at least one portion of said second layer remains permanently implanted, while said at least one portion of said first layer and said at least one portion of said third layer are absorbed.

7. The hernia repair device of claim 6, wherein said first and third layers are made in their entirety from said absorbable textile material.

8. The hernia repair device of claim 7, further comprising expanding means for expanding said patch into its planar configuration, said expanding means being made from a second absorbable material so as to be absorbed when said patch is implanted in a patient'"'"'s body.

9. The hernia repair device of claim 8, wherein said expanding means includes a spring located in said pouch.

10. The hernia repair device of claim 9, wherein said third layer cooperates with said first layer and said second layer to form said patch.

11. The hernia repair device of claim 10, wherein said absorbable textile material is polyglactin.

12. The hernia repair device of claim 11, wherein said second absorbable material is polydioxanone.

13. The hernia repair device of claim 12, wherein said non-absorbable material is polypropylene.

14. The hernia repair device of claim 13, further comprising receiving means, in communication with said pouch, for receiving at least one finger of a person.

15. The hernia repair device of claim 14, wherein said receiving means includes a slit formed in one of said first and third layers.

16. The hernia repair device of claim 6, wherein said second layer is contained in said pouch without being attached to any one of said first and third layers.

17. The hernia repair device of claim 6, wherein said at least one portion of said first layer and said at least one portion of said third layer are made from a material so as to be completely absorbed in a patient'"'"'s body within a certain period of time.

18. The hernia repair device of claim 17, wherein said period of time is in a range from about fifty days to about ninety days.

19. The hernia repair device of claim 6, wherein said absorbable textile material is polyglactin.

20. The hernia repair device of claim 6, wherein said nonabsorbable textile material is polypropylene.
