Polypropylene-Polyethylene Composite Mesh

What Duolene Mesh Is

Duolene is a sterile, non-absorbable composite mesh designed for hernia repair. The dual-sided prosthesis is intended to support tissue integration on one side while providing a barrier on the visceral side. It is used for the reconstruction of soft-tissue deficiencies and is intended for use by a qualified surgeon trained in mesh implantation and the relevant surgical techniques.

Composition and Construction

Duolene is composed of one layer of knitted lightweight polypropylene mesh for the parietal side and one layer of medical-grade polyethylene film for the visceral side. Both functional layers are fused together using a process that does not rely on adhesive. The polypropylene surface is macroporous and is intended to encourage tissue ingrowth on the parietal side, while the extruded, expanded, low-porosity polyethylene film is intended to act as a barrier and to minimise tissue ingrowth and foreign body reaction on the visceral side. The mesh also contains micropores intended to allow seroma drainage.

Characteristics and Handling

Duolene is transparent, allowing visualisation of the underlying anatomy, and its thin, lightweight design is intended to support rolling and laparoscopic placement. A placement marker is provided to assist orientation. The mesh can be fixed with sutures or tackers. Selection of size, orientation and fixation method is at the discretion of the surgeon, based on the patient’s condition, the type and location of the defect, and operative requirements.

Applications

Duolene is designed for use in:

• Ventral / incisional hernia
• Para-umbilical hernia
• Umbilical hernia
• Inguinal hernia — direct and indirect
• Femoral hernia
