Urethral support implant for the treatment of male urinary incontinence

Manufacturing process for a urethral support sling implant for treatment of male urinary incontinence, produced in a biocompatible material, comprising a central part forming an area adapted for supporting the urethra, including an inferior base prolonged in a same plane by two opposite trans-obturator arms, the inferior base being prolonged upwards by a section extending beyond said inferior base, the section also extending as two pre-pubic arms configured in a ‘V’ relative to each other, and each of said pre-pubic arms being configured in a ‘V’ at an angle greater than 45° relative to subjacent trans-obturator arms, the trans-obturator arms and the pre-pubic arms being made of a same material as the central part, wherein the process comprises:

• cutting the pre-pubic arms, the trans-obturator arms and the central part from a knitted fabric having a first direction, and a second direction, transverse to the first direction, the first direction being of higher mechanical strength than the second direction, the second direction being of higher extensibility than the first direction, cutting said trans-obturator arms as a single continuous strip extending in the first direction from the knitted fabric, cutting the pre-pubic arms and the central part out of the knitted fabric as a single unit, separate from the trans-obturator arms, and with the pre-pubic arms extending primarily in the first direction, and assembling the trans-obturator arms to the central part with zig-zag stitching of sewing thread to absorb deformations and mechanical strains when the trans-obturator arms are put under tension, without risk of the sewing thread breaking prematurely.
