Materials

Although mesh use has significantly improved the outcomes of hernia and pelvic organ prolapse repair long-term recurrence rates remain unacceptably high We aim to determine the in vivo degradation and functional outcome of reconstructed abdominal wall defects using slowly degradable electrospun ureidopyrimidinone moieties incorporated into a polycarbonate backbone (UPy-PC) implant compared

Hernia Mesh

Polypropylene one of the world's most widely produced plastics was used in the first modern hernia mesh surgery in 1958 Since then manufacturers have produced mesh from other synthetic materials that include brand names like GoreTex which is used in outerwear and Teflon which is

Bioprosthetic Mesh in Abdominal Wall Reconstruction

The Radiologic Appearance of Prosthetic Materials Used in

jority of polypropylene and polyester mesh-es are knitted As far as radiopaque proper-ties of meshes are concerned in general more mass implies greater visibility Even if meshes have identical chemical compositions a mesh with a dense homogeneous (i e not-woven and not-knitted) structure will be more visible than a tightly woven or knitted mesh and the latter will be more visible than

The Impact of Boundary Conditions on Surface

These data support the hypothesis that regional increases in the concentration of mesh potentially enhance the host׳s foreign body response leading to exposure The Impact of Boundary Conditions on Surface Curvature of Polypropylene Mesh in Response to Uniaxial Loading by William R Barone

However polypropylene and polyvinylidene fluoride meshes demonstrated a sustained chronic inflammatory response profile by 90 days In contrast poly-L-lactic acid and polyurethane meshes integrated well into host tissues with a decreased inflammatory response indicative of

Ultrasound appearances after mesh

Polypropylene meshes are frequently used in abdominal and vaginal reconstructive surgery Recently several authors have claimed that mesh-associated complications may be linked to mesh shrinkage We have performed a prospective study with postoperative follow-up by ultrasound examination at two time points after Prolift anterior implantation to assess changes in the ultrasound appearance of

The Impact of Boundary Conditions on Surface Curvature

These data support the hypothesis that regional increases in the concentration of mesh potentially enhance the host׳s foreign body response leading to exposure Exposure following pelvic organ prolapse repair has been observationally associated with wrinkling of the implanted mesh The purpose of this study was to quantify the impact of variable boundary conditions on the out-of-plane

Porosity and tensioning: Critical factors to consider when

We compared the response following implantation of the prototype prolapse mesh to that of newer generation prolapse meshes (lower weight increased pore size/porosity lower stiffness) the newer materials had less of a negative effect however no particular mesh characteristic was predictive of the host response Most critically our studies revealed that a mesh's pre-implantation
