Selective Bonding
Discover how Medibrane sets your project apart from the rest
What Is It?
We use selective bonding technology to precisely control how membranes are bonded to scaffolds.
Our process enables partial or full bonding, allowing us to tailor flexibility, strength, and sealing performance to the exact requirements of each medical device.
By combining selective bonding with microlayer polymer deposition, we engineer membranes and scaffold covers with highly controlled mechanical and surface properties.
Why Does It Matter?
Medical devices must closely match the mechanical behavior of blood vessels to ensure safe, long-term performance. Mismatches in stiffness, compliance, or wall thickness can lead to turbulence, thrombosis, graft failure, and reinterventions.
In addition, device profile and deliverability directly affect procedural success, patient eligibility, and clinical outcomes.
Precise bonding and ultra-thin structures are critical to meeting these challenges.
How Does It Help?
Our selective bonding approach delivers clear performance and design advantages:
-
Customizable bonding patterns (e.g., 25%, 50%, or full coverage) to balance flexibility and strength
-
Selective sealing with partial or full sealing capability up to 150 psi, while preserving scaffold surface properties
-
Thinner walls that enable smaller delivery systems and lower-profile implants
-
Reduced loading and deployment forces for smoother handling and reliable placement
-
Improved flexibility and compliance to mimic vessel behavior and support stable blood flow
-
Enhanced navigation through complex anatomy for minimally invasive procedures
Selective bonding also provides a unique mechanical advantage by influencing how the membrane and scaffold interact during compression and expansion.
By limiting adhesion to specific regions, the membrane can move more freely relative to the scaffold during crimping, significantly reducing loading forces and minimizing stress on both materials.
This controlled interface helps prevent wrinkling, buckling, or localized strain concentrations that can occur in fully bonded systems.
In parallel, selective bonding enables fine‑tuning of radial force.
By adjusting the bonding pattern, coverage, and distribution, we can modulate how the scaffold transmits outward force once deployed. This allows for more predictable expansion behavior, improved wall apposition, and reduced risk of excessive radial pressure on delicate vessels.
The result is a device that loads more smoothly, deploys more consistently, and achieves a better balance between support and compliance.
