Abstract

A surgical implant for supporting pelvic anatomy includes a first fixing zone, a second fixing zone, and a supporting zone. The first fixing zone has a retaining portion that is absorbable and formed of a fiber entanglement and a mesh for anchoring the first fixing zone in soft tissues in a space defined by a pelvis. The second fixing zone has a retaining portion that is absorbable and formed of a fiber entanglement and a mesh for anchoring the second fixing zone in soft tissues in a space defined by a pelvis. The supporting zone is formed of a mesh and is interposed between the first and second fixing zones.

Claims

1. A surgical implant for supporting pelvic anatomy, the implant comprising:

a first fixing zone having a retaining portion that is absorbable and formed of a fiber entanglement and a mesh for anchoring the first fixing zone in soft tissues in a space defined by a pelvis;

a second fixing zone having a retaining portion that is absorbable and formed of a fiber entanglement and a mesh for anchoring the second fixing zone in soft tissues in a space defined by a pelvis; and

a supporting zone, the supporting zone being formed of a mesh and being interposed between the first and second fixing zones.

2. The surgical implant of claim 1, wherein the surgical implant is adapted for anchoring the first and second fixing zones in the retropubic space without penetrating the rectus sheath.

3. The surgical implant of claim 1, wherein the length of the implant is from 8 cm to 20 cm.

4. The surgical implant of claim 1, wherein the length of each of the first and second fixing zones is at least 1 cm and not greater than 8 cm.

5. The surgical implant of claim 1, wherein the mesh material of the supporting zone includes strands forming major spaces of 1 mm to 10 mm in size.

6. The surgical implant of claim 1, wherein each of the first and second fixing zones has a pointed end.

7. The surgical implant of claim 1, wherein the mesh of the first fixing zone, the mesh of the second fixing zone, and the mesh of the supporting zone are integral.

8. The surgical implant of claim 1, wherein the first and second fixing zones are adapted to be anchored in soft tissue to resist a force of dislodgement of no more than 3N.

9. The surgical implant of claim 1, wherein the first and second fixing zones are adapted to be anchored in soft tissue to resist a force of dislodgement of no more than 5N.

10. The surgical implant of claim 1, wherein the first and second fixing zones are adapted to be anchored in soft tissue to resist forces of dislodgement of no more than 10N.
