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 formed of a plurality of fiber entanglements located along a substantial portion of a length of the first fixing zone and a mesh for anchoring the first fixing zone in soft tissue in a space defined by a pelvis, the first fixing zone including a portion that is absorbable, each fiber entanglement forming an enlarged mass defining an outer surface adapted to anchor the first fixing zone in soft tissue of the pelvis;

a second fixing zone formed of a plurality of fiber entanglements located along a substantial portion of a length of the second fixing zone and a mesh for anchoring the second fixing zone in soft tissue in a space defined by a pelvis, the second fixing zone including a portion that is absorbable, each fiber entanglement forming an enlarged mass defining an outer surface adapted to anchor the second fixing zone in soft tissue of the pelvis, and wherein each fixing zone is adapted to initially secure the surgical implant in the soft tissue upon insertion of each fixing zone in soft tissue of the pelvis without an additional anchoring mechanism; 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 up to 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 up to 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 up to 10N.

11. The surgical implant of claim 1, wherein the first fixing zone is substantially flat and includes a first edge and a second edge, the first and second edges being tapered toward one another.

12. The surgical implant of claim 11, wherein the first edge and the second edge are tapered toward a middle section of the first fixing zone.

13. The surgical implant of claim 1, wherein the first fixing zone includes at least one aperture adapted to receive and cooperate with a tool for insertion of the implant into the space defined by the pelvis.

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

a first fixing zone formed of a plurality of fiber entanglements located along a substantial portion of a length of the first fixing zone and a mesh for anchoring the first fixing zone in soft tissue in a space defined by a pelvis, the first fixing zone including a portion that is absorbable, each fiber entanglement forming a disorganized mass defining an outer surface adapted to anchor the first fixing zone in soft tissue of the pelvis;

a second fixing zone formed of a plurality of fiber entanglements located along a substantial portion of a length of the second fixing zone and a mesh for anchoring the second fixing zone in soft tissue in a space defined by a pelvis, the second fixing zone including a portion that is absorbable, each fiber entanglement forming a disorganized mass defining an outer surface adapted to anchor the second fixing zone in soft tissue of the pelvis, and wherein each fixing zone is adapted to initially secure the surgical implant in the soft tissue upon insertion of each fixing zone in soft tissue of the pelvis without an additional anchoring mechanism; and

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