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 having a first portion and a second portion, the first portion of the first flap configured to be attached proximate to a sacrum of a patient and the second portion of the first flap configured to be attached proximate to an anterior vaginal wall of the patient; and

a second flap having a first portion and a second portion, the first portion of the second flap configured to be attached proximate to the sacrum of the patient and the second portion of the second flap configured to be attached to a posterior vaginal wall of the patient,

wherein a value corresponding to a biomechanical parameter defining a biomechanical attribute of the second portion of the first flap and a value of the biomechanical parameter defining the biomechanical attribute of the second portion of the second flap are different from each other,

wherein the biomechanical attribute of the second portion of the first flap is configured to emulate biomechanical properties of the anterior vaginal wall of the patient and the biomechanical attribute of the second portion of the second flap is configured to emulate biomechanical properties of the posterior vaginal wall of the patient.

2. The implant of claim 1, wherein an entirety of the first flap includes a first type of knit structure and an entirety of the second flap includes a second type of knit structure, wherein the first type of knit structure and the second type of knit structure are different from each other.

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

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

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

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

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

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

9. A tubular implant comprising:

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

a second portion of the tubular implant, the second portion defining a second lumen, the second lumen directly extending from the first lumen, the second portion including a proximal end portion and a distal end portion, the proximal end portion being adjacent to the first portion, the second portion including a first section and a second section and two slits separating the first section and the second section, the two slits extend substantially entirely from the proximal end portion to the distal end portion,

a transition region defined by an intersection of the first portion, the first section, and the second section, the two slits extending to the transition region,

wherein a value corresponding to a biomechanical parameter defining a biomechanical attribute of the first portion and a value of the biomechanical parameter defining the biomechanical attribute of the second portion are different from each other,

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, wherein a knit structure of the first section is different from a knit structure of the second section of the section portion.

10. The tubular implant of claim 9, wherein a knit structure of the first portion is different from a knit structure of the second portion.

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

inserting the implant inside the body;

attaching a first portion of a first flap of the implant to a sacrum of the patient, the first portion of the first flap defining a first value of a biomechanical parameter defining a biomechanical attribute, wherein an entirety of the first portion of the first flap defines a first pore construct having a first pore size;

attaching a second portion of the first flap of the implant to an anterior vaginal wall, the second portion of the first flap attaching to the anterior vaginal wall defining a second value of the biomechanical parameter defining the biomechanical attribute, wherein an entirety of the second portion of the first flap defines a second pore construct having a second pore size;

attaching a first portion of a second flap of the implant to the sacrum of the patient; and

attaching a second portion of the second flap of the implant to a posterior vaginal wall, the second portion of the second flap attaching to the posterior vaginal wall defining a third value of the biomechanical parameter defining the biomechanical attribute, wherein an entirety of the second portion of the second flap defines a third pore construct having a third pore size,

wherein the first value, the second value, and the third value of the biomechanical parameter are different from each other,

wherein the biomechanical attribute of the second portion of the first flap is configured to emulate biomechanical properties of the anterior vaginal wall of the patient and the biomechanical attribute of the second portion of the second flap is configured to emulate biomechanical properties of the posterior vaginal wall of the patient,

wherein the first pore size, the second pore size, and the third pore size are different from each other.
