An implantable prosthetic mesh for repair of an inguinal hernia. The prosthetic mesh includes a conforming soft mesh portion and two displaced portions each having a three dimensional shape and constructed of a stiffer mesh material. The soft mesh portion can be draped over the tissue and spermatic cords, and the two three-dimensional portions formed from the stiffer mesh material are adapted to enter into and be received deep within the respective space defined in the anatomy at each of direct and indirect spaces surrounding the inferior epigastric vessels.

1. A method of repairing a tissue defect in a patient, the patient having on a medial side a direct space located between inferior epigastric vessels, a medial rectus muscle, and an iliopubic tract and a femoral ring defined between the inferior epigastric vessels, the iliopubic tract, and a spermatic cord, and on a lateral side an indirect space defined as lateral to the inferior epigastric vessels and anterior to the iliopubic tract, the method comprising: a) providing a prosthetic mesh having a relatively soft conforming first mesh material, and first and second three-dimensional portions of a stiffer second mesh material that are displaced from each other, each of the first and second three-dimensional portions having a first convex surface and an opposing second concave surface; andb) placing the first mesh material over the spermatic cord and the first and second three-dimensional portions at the direct and indirect spaces, respectively, wherein the convex surfaces of the first and second three-dimensional portions extend into the direct and indirect spaces to thereby anchor the prosthetic mesh relative to the tissue defect. 2. A method according to claim 1, further comprising: using the spermatic cord as a pillar to prevent medial-lateral dislocation of the prosthetic mesh. 3. A method according to claim 1, further comprising conforming said first mesh material over the inferior epigastric vessels and the spermatic cord. 4. A method according to claim 1, wherein: said prosthetic mesh is asymmetric such that one of said first and second three-dimensional portions is larger than the other of said first and second three-dimensional portions. 5. A method according to claim 1, wherein: said second three-dimensional portion is located lateral of said first three-dimensional portion. 6. A method according to claim 1, wherein: said first and second three-dimensional portions are displaced from each other by 1 to 2.5 cm. 7. A method according to claim 6, wherein: said first three-dimensional portion has a diameter of 2.5±1 cm,said second three-dimensional portion has a diameter of 3.0±1 cm, andsaid first and second three-dimensional portions are displaced from each other in a medial-lateral dimension by 1-2.5 cm. 8. A method according to claim 1, wherein: said first three-dimensional portion has a diameter of 2.5±1 cm,said second three-dimensional portion has a diameter of 3.0±1 cm, andsaid first and second three-dimensional portions are displaced from each other in a medial-lateral dimension by 1-2.5 cm. 9. A method according to claim 1, wherein: the first and second three-dimensional portions are displaced from each other in a medial-lateral direction, and the provided prosthetic mesh is asymmetric in the medial-lateral direction. 10. A method according to claim 1, wherein: the first mesh material has first and second central openings, and the first and second three-dimensional portions are coupled within the first and second central openings, respectively. 11. A method of repairing a tissue defect in a patient, the patient having on a medial side a direct space located between inferior epigastric vessels, a medial rectus muscle, and an iliopubic tract, and a femoral ring defined between the inferior epigastric vessels, the iliopubic tract, and a spermatic cord, and on a lateral side an indirect space defined as lateral to the inferior epigastric vessels and anterior to the iliopubic tract, the method comprising: a) providing a prosthetic mesh having first and second three-dimensional portions, each with a convex side, that are displaced from each other by a third mesh portion, each of said first and second three-dimensional portions having a stiffer mesh construction than said third mesh portion, the prosthetic mesh provided in a rolled form;b) inserting the rolled mesh into a laparoscopic port;c) advancing the rolled mesh out of the port to the site of tissue defect; andd) maneuvering the mesh so that, the first three-dimensional portion is located on the medial side and seated convex side down within the direct space,the second three-dimensional portion is located on the lateral side and seated convex side down within the indirect space, andthe third mesh portion is draped across the epigastric vessels and spermatic cord. 12. A method according to claim 11, wherein: said first and second three-dimensional portions are displaced from each other by 1 to 2.5 cm. 13. A method according to claim 12, wherein: said first three-dimensional portion has a maximum diameter of 2.5±1 cm,said second three-dimensional portion has a maximum diameter of 3.0±1 cm, andsaid first and second three-dimensional portions are displaced from each other in a medial-lateral dimension by 1-2.5 cm. 14. A method according to claim 11, wherein: said first three-dimensional portion has a maximum diameter of 2.5±1 cm,said second three-dimensional portion has a maximum diameter of 3.0±1 cm, andsaid first and second three-dimensional portions are displaced from each other in a medial-lateral dimension by 1-2.5 cm. 15. A method of repairing a tissue defect in a patient, the patient having on a medial side a direct space located between inferior epigastric vessels, a medial rectus muscle, and an iliopubic tract and a femoral ring defined between the inferior epigastric vessels, the iliopubic tract, and a spermatic cord, and on a lateral side an indirect space defined as lateral to the inferior epigastric vessels and anterior to the iliopubic tract, the method comprising: a) providing a prosthetic mesh having a relatively soft tissue conforming first mesh material, and stiffer first and second convex mesh portions extending from the first mesh material and which are displaced from each other by the first mesh material; andb) placing the first mesh material over the spermatic cord, and the first and second convex mesh portions into the direct and indirect spaces, respectively. 16. A method according to claim 15, further comprising: inserting the prosthetic mesh into a laparoscopic port; andadvancing the prosthetic mesh out of the port to the site of tissue defect, wherein said providing includes providing the prosthetic mesh in a rolled form. 17. A method according to claim 15, wherein: the provided prosthetic mesh is asymmetric such that the first convex mesh portion is smaller than the second convex mesh portion. 18. A method according to claim 15, wherein: the first and second convex mesh portions are displaced from each other in a medial-lateral direction, and the provided prosthetic mesh is asymmetric in the medial-lateral direction. 19. A method according to claim 15, further comprising: using the spermatic cord as a pillar to prevent medial-lateral dislocation of the prosthetic mesh. 20. A method according to claim 15, wherein: the first and second convex mesh portions are displaced from each other by 1 to 2.5 cm. 21. A method according to claim 20, wherein: the first convex mesh portion has a maximum diameter of 2.5±1 cm,the second convex mesh portion has a maximum diameter of 3.0±1 cm, andthe first and second convex mesh portions are displaced from each other in a medial-lateral dimension by 1-2.5 cm.
