Abstract

A method for supporting a urethra of a patient includes making an incision on an upper wall of a vagina of the patient and inserting a first end of a surgical implant through the incision and on a first side of a urethra of the patient. The first end of the surgical implant has a first fixing zone with a retaining portion that is formed of a fiber entanglement and a mesh.

Claims

1. A method for supporting a urethra of a patient, the method comprising:

making an incision on an upper wall of a vagina of the patient;

inserting a first end of a surgical implant through the incision and on a first side of a urethra of the patient, the first end including a first fixing zone having a retaining portion that is absorbable and formed of a fiber entanglement and a mesh;

anchoring the first fixing zone in soft tissue of a pelvis without penetrating a rectus sheath;

inserting a second end of the surgical implant through the incision and on a second side of the urethra such that a supporting zone of the surgical implant is located beneath the urethra, the second end including a second fixing zone having a retaining portion that is absorbable and formed of a fiber entanglement and a mesh and the supporting zone of the surgical implant being formed of a mesh and being interposed between the first and second fixing zones; and

anchoring the second fixing zone in soft tissue of the pelvis without penetrating the rectus sheath, the first and second fixing zones being anchored such that the supporting zone passes loosely under the urethra.

2. The method of claim 1, further comprising anchoring the first and second fixing zones in a retropubic space.

3. The method of claim 1, further comprising anchoring the first and second fixing zones such that the supporting zone passes under a mid-urethra.

4. The method of claim 1, further comprising anchoring the first and second fixing zones in soft tissues of the pelvis such that the surgical implant resists a force of dislodgement of no more than 5N.

5. The method of claim 1, further comprising anchoring the first and second fixing zones in soft tissues of the pelvis such that the surgical implant resists a force of dislodgement of no more than 10N.

6. The method of claim 1, wherein the surgical implant being inserted has a length from 8 cm to 20 cm.

7. The method of claim 1, wherein each of the first and second fixing zones of the surgical implant being inserted has a length that is at least 1 cm and not greater than 8 cm.

8. The method of claim 1, wherein the mesh material of the supporting zone being passed loosely under the urethra includes strands forming major spaces of 1 mm to 10 mm in size.

9. The method of claim 1, wherein each of the first and second fixing zones being inserted has a pointed end.

10. The method of claim 1, wherein the meshes of the first fixing zone, the second fixing zone, and the supporting zone of the surgical implant being inserted are integral.
