VitaMESH™ Macroporous PP Surgical Mesh

VitaMESH™ Macroporous PP Surgical Mesh is an implant suitable
for different types of fascial defects, including inguinal hernia repair. VitaMESH provides the favourable
ingrowth and healed strength characteristics of a large pore monofilament
polypropylene surgical mesh with optimised handling and biocompatibility attributes
in one high performance implant of condensed polypropylene (cPP).

Featurescharacteristics of biomaterial for hernia repair

Uniformly strong : Strong and durable cPP surgical mesh material maintains consistent levels of strength while avoiding the problems associated with composite surgical meshes1,3

Transparent : Transparent open pore structure in surgical mesh facilitate fast incorporation and visualization of underlying tissue structures 1

Smooth : Up to 80% reduction
in thickness and a low coefficient of friction over predicate surgical mesh devices improving ease of use and trocar deployment in laparoscopic procedures

characteristics of biomaterial for hernia repairThin : Thin wall structure with less surgical mesh material for reducing scar tissue build up and minimizing patient discomfort

Macroporous : Macroporous open pore structure promoting rapid healing and dense collagen formation

Biocompatible : Surface area and void area reduction for improving healing and biocompatibility2
