Adhera Surface Activation
Discover how Medibrane sets your project apart from the rest
What Is It?
We use Adhera surface activation to enhance adhesion between metals and polymers, as well as between different polymer types such as fluoropolymers and thermoplastics.
Our process creates strong chemical bonds, with optional mechanical interaction, resulting in durable and reliable adhesion for demanding medical device applications.
In addition, we encapsulate metal components with an ultra-thin binding polymer layer to maximize bond strength while minimizing material thickness.
Why Does It Matter?
Delamination of a stent graft cover directly threatens patient safety and device reliability.
It can lead to endoleaks, structural failure, or rupture, putting patients at risk.
For manufacturers, delamination often results in:
-
Product recalls
-
Regulatory and compliance issues
-
Legal liability
-
Long-term reputational damage
Adhera surface activation helps stop delamination at its source, supporting consistent performance, regulatory compliance, and sustained clinical trust.
How Does It Help?
Traditional stent covering techniques require full encapsulation of the metal scaffold to achieve mechanical interlocking, resulting in cover wall thicknesses of approximately 100 microns (0.004").
By forming a strong chemical bond between the metal and cover polymer, Adhera surface activation eliminates the need for mechanical interlocking.
This allows manufacturers to reduce cover thickness to as little as 12 microns (0.0005"), enabling:
-
Lower crossing profiles
-
Increased flexibility
-
Advanced stent graft designs
Why Does It Last?
Mechanical interlocking in traditional stent graft covers can loosen during crimping, deployment, and long-term fatigue, creating blood-filled voids around stent struts that may promote thrombus formation.
Adhera surface activation creates a direct chemical bond between the stent cover and metal, significantly reducing void formation and improving long-term safety and durability.
