The POLYTECH Implant Shell Surfaces

A range of surfaces to meet surgeons’ and patients’ needs

POLYTECH’s high quality implant shells are made from a silicone elastomer, a high-performance material that is particularly resistant to chemical and mechanical effects. 
Composed of multiple different layers, the shell has a well-defined structure including a special barrier layer that is designed to prevent silicone oils from migrating.
POLYTECH implants are provided with a range of shell surface textures and with the proprietary shell cover Microthane®

POLYTECH implants are independently tested by the State Materials Testing Institute Darmstadt and the surface texture is classified with the EN ISO 14607: 2018 – the only official and shared classification method.

 

MESMO®

Fine microtextured shell surface

The MESMO® fine microtextured implant shell surface is appreciated for its properties and ease of use which allows MESMO® to be utilised for a variety of indications.
Available in round and anatomical implant shapes, and in 4 projections: Low, Moderate, High and Extra High. 

MESMO® fine microtextured shell combines the benefits of both smooth and textured surfaces. The capsular contracture rates for MESMO® surface is low3. 

Microthane®

Micro-polyurethane shell covered

Microthane® is the proprietary name for POLYTECH's micro-polyurethane foam covered implant shell. 

Microthane® implants are designed to:

  • Act as a ‘tissue scaffold’
  • Facilitate tissue ingrowth and integration to enhance implant stability
  • Minimise capsular contracture and reduce seroma
  • Deliver stable, predictable and long-lasting results that provide beautiful natural looking breasts

Microthane® – difference you can feel

What is the difference between POLYTECH Microthane® implants and traditional silicone implants?

Microthane® implants are POLYTECH’s high-quality silicone implants covered with a layer of micro polyurethane foam. 

This creates a 3D open pore matrix which acts like an internal tissue scaffold with a specific mode of action.  

Following implantation, the contact area between the implant cover and the surrounding tissue provides a tissue favouring transition layer into which the natural healing process develops, creating maximum adherence between the implant and the tissue.

Bio-favouring implant surface

Progressively, over the course of several weeks, the implant’s Microthane® cover will fill with healthy and highly vascularized tissue, allowing the body’s immune system to be active at the very surface of the implant.

This reduces the risk of capsular contracture, device rotation and displacement.

POLYtxt® 

POLYTECH Microtextured shell surface

This microtextured surface is manufactured to provide a greater surface irregularity than MESMO® yet with gentle contours. 
POLYtxt® is designed to provide greater surface irregularity to deliver greater tissue adherence. 

Available in round and anatomical shapes, and in 4 projections: Low, Moderate, High and Extra High. 

POLYtxt® surface is available in 80 markets and implanted in hundreds of thousands of satisfied patients worldwide.

POLYsmoooth™

POLYTECH smooth shell surface

The first silicone breast implants had a smooth shell surface. Smooth surface is still in use today all over the world. The POLYTECH smooth surface is called POLYsmoooth™.

POLYTECH smooth shell surface has an advanced shell construction with a smooth surface. Available in a round shape and 4 projections: Low, Moderate, High and Extra High.
