Abstract

The invention discloses an implant. The implant may include a first flap and a second flap. The first flap may further include a first portion, a second portion and a transition region. The first portion may be configured to be attached proximate a sacrum. The second portion may be configured to be attached to an anterior vaginal wall. The transition region lies between the first portion and the second portion. The second flap may be fabricated such that a portion of the second flap is configured to be attached to a posterior vaginal wall. The implant may be configured such that a value corresponding to a biomechanical parameter defining a biomechanical attribute of the portion of the first flap attaching to the anterior wall is different from a value of the biomechanical parameter defining the biomechanical attribute of the portion of the second flap attaching to the posterior wall.

Claims

1. An implant comprising:

a first flap formed of a sheet of material including;

a first portion configured to be attached proximate a sacrum;

a second portion configured to be attached to an anterior vaginal wall; and

a transition region lying between the first portion and the second portion; and

a second flap such that a portion of the second flap is configured to be attached to a posterior vaginal wall,

wherein a value corresponding to a biomechanical parameter defining a biomechanical attribute of the second portion of the first flap attaching to the anterior wall is different from a value of the biomechanical parameter defining the biomechanical attribute of the first portion of the first flap attaching proximate the sacrum, the sheet of material having a weight less than 30 grams per square meter.

2. The implant of claim 1, wherein the first portion of the first flap defines a first type of knit structure.

3. The implant of claim 2, wherein the second portion of the first flap defines a second type of knit structure

4. The implant of claim 1, wherein a width of the second portion is substantially more than a width of the first portion of the first flap.

5. The implant of claim 4, wherein the second portion includes a proximal end and a distal end, the distal end being proximate the transition region, wherein the width of the second portion varies from the proximal end to the distal end of the second portion.

6. The implant of claim 5, wherein the varying second width along the second portion defines a trapezoidal shape of the second portion.

7. The implant of claim 1, wherein the transition region defines a third type of knit structure.

8. The implant of claim 1, wherein each of the first and the second flaps defines a planar shape and are configured to be attached separately to bodily locations.

9. The implant of claim 1, wherein the biomechanical attribute is elasticity and the biomechanical parameter is a modulus of elasticity.

10. The implant of claim 1, wherein the biomechanical attribute is viscoelasticity.

11. The implant of claim 1, wherein the biomechanical attribute is viscohyperelasticity.

12. The implant of claim 1, wherein the biomechanical attribute is anisotropicity.

13. The implant of claim 1, wherein the biomechanical attribute is resistance to creep.

14. The implant of claim 1, wherein the biomechanical attribute is stiffness.

15. An implant, comprising:

a sheet of material having a first portion and second portion, wherein a value corresponding to a biomechanical parameter of the first portion of the sheet of material being different from a value of the biomechanical parameter second portion of the sheet of material, the first portion of the sheet of material having a weight that is different than the second portion of the sheet of material.

16. The implant of claim 15, wherein the biomechanical parameter is the ability to stretch.

17. The implant of claim 15, wherein the biomechanical parameter is the ability to flex.

18. The implant of claim 15, wherein the biomechanical parameter is stiffness.

19. The implant of claim 15, wherein one portion of the sheet of material has a weight greater than 30 grams per square meter and another portion of the material has a weight of less than 30 grams per square meter.

20. The implant of claim 15, wherein the first portion of the sheet of material has a first knit pattern and the second portion of the sheet of material has a second knit pattern different than the first knit pattern.
