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 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 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.

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 each of the value of the biomechanical parameter defining the biomechanical attribute of the portion of the first flap attaching to the anterior wall and the value of the biomechanical parameter defining the biomechanical attribute of the portion of the second flap attaching to the posterior wall is different from a value of the biomechanical parameter of the first portion attaching proximate the sacrum.

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

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

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

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

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

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

16. The implant of claim 1, wherein the first flap and the second flap are constructed from a single piece of material.

17. A tubular implant comprising:

a first portion of the tubular implant configured to be attached proximate a sacrum;

a transition region extending from the first portion;

a second portion of the tubular implant and extending from the transition region monolithically and including a first section and a second section and two slits provided laterally in the second portion configuring the first section as apart from the second section at a proximal end; and

a lumen defined within the first and second portions of the tubular implant,

wherein the first section is configured to be attached to an anterior vaginal wall, and the second section is configured to be attached to a posterior vaginal wall.

18. The tubular implant of claim 17, wherein a knit structure of the first portion is different from a knit structure of the second portion.

19. The tubular implant of claim 17, wherein a knit structure of the first section is different from a knit structure of the second section of the section portion.

20. A method for placing an implant in a body of a patient, the method comprising:

inserting the implant inside the body;

attaching a portion of the implant to an anterior vaginal wall, wherein the portion attaching to the anterior vaginal wall defines a first value of a biomechanical parameter defining a biomechanical attribute; and

attaching a portion of the implant to a posterior vaginal wall, wherein the portion attaching to the posterior vaginal wall defines a second value of the biomechanical parameter such that the second value corresponding to the portion attaching to the posterior wall is different from the first value corresponding to the portion attaching to the anterior wall.
