An implant configured to be delivered and placed in a patient's body for the treatment of pelvic floor disorder, the implant comprises: a first flap (102; 248) including: a first portion (104; 202) configured to be attached proximate a sacrum; a second portion (106; 204) configured to be attached to an anterior vaginal wall; and a transition region (108; 206) lying between the first portion (104; 202) and the second portion (106; 204); and a second flap including: a first portion; a second portion configured to be attached to a posterior vaginal wall; and a transition region characterised in that a value corresponding to a biomechanical parameter defining a biomechanical attribute of the second portion (106; 204) of the first flap (102; 248) attaching to the anterior vaginal wall is different from a value of the biomechanical parameter defining the biomechanical attribute of the second portion of the second flap attaching to the posterior vaginal wall, wherein the first portion (104; 202) of the first flap (102; 248) defines a first type of knit structure, and the second portion (106; 204) of the first flap (102; 248) defines a second type of knit structure, wherein the biomechanical attribute is one of the following: elasticity, viscoelasticity, viscohyperelasticity, anisotropicity, resistance to creep and stiffness. a first flap (102; 248) including: a first portion (104; 202) configured to be attached proximate a sacrum; a second portion (106; 204) configured to be attached to an anterior vaginal wall; and a transition region (108; 206) lying between the first portion (104; 202) and the second portion (106; 204); and a first portion (104; 202) configured to be attached proximate a sacrum; a second portion (106; 204) configured to be attached to an anterior vaginal wall; and a transition region (108; 206) lying between the first portion (104; 202) and the second portion (106; 204); and a second flap including: a first portion; a second portion configured to be attached to a posterior vaginal wall; and a transition region characterised in that a value corresponding to a biomechanical parameter defining a biomechanical attribute of the second portion (106; 204) of the first flap (102; 248) attaching to the anterior vaginal wall is different from a value of the biomechanical parameter defining the biomechanical attribute of the second portion of the second flap attaching to the posterior vaginal wall, a first portion; a second portion configured to be attached to a posterior vaginal wall; and a transition region characterised in that a value corresponding to a biomechanical parameter defining a biomechanical attribute of the second portion (106; 204) of the first flap (102; 248) attaching to the anterior vaginal wall is different from a value of the biomechanical parameter defining the biomechanical attribute of the second portion of the second flap attaching to the posterior vaginal wall, wherein the first portion (104; 202) of the first flap (102; 248) defines a first type of knit structure, and the second portion (106; 204) of the first flap (102; 248) defines a second type of knit structure, wherein the biomechanical attribute is one of the following: elasticity, viscoelasticity, viscohyperelasticity, anisotropicity, resistance to creep and stiffness.
