Medibrane’s Sutureless Lamination Technology: Transforming Stent Covers

At Medibrane, our Sutureless Lamination technology revolutionizes how we cover stents and implants. Our expert team developed this unique solution after extensive research into medical device requirements and the biomedical industry. This technology replaces the traditional suturing method, providing a fast, reliable, and easy-to-manufacture process to create high-quality stent covers.

Types of Covered Stents

Covered stents are commonly used in various medical applications, such as abdominal aortic aneurysm vascular stents and gastrointestinal tract non-vascular stents. These stents are typically covered with materials like Polyethylene terephthalate (PET), Polyester, or polytetrafluoroethylene (PTFE). Fabric covers are also essential for structural heart devices, including heart valves, left atrial appendage devices, and mitral valve clips.

The Advantages and Challenges of Fabric Covers

Fabric covers provide key benefits, such as directing fluid and allowing tissue ingrowth. Their porous structure helps with both sealing and tissue attachment. However, the same porous quality can lead to blood clot accumulation, which limits the use of fabric covers in vascular stents for smaller blood vessels.

Overcoming Suturing with Innovative Technology

Previously, fabric coverings relied on suturing, a manual and time-consuming process. Medibrane’s experts solved this problem by developing the Adhesion Platform, which laminates the fabric to the stent without using sutures.

Medibrane’s Adhesion Platform: Ensuring Strong Bonds

The Adhesion Platform was designed to improve adhesion between the metal stent and the fabric covering. This platform ensures a strong, long-lasting attachment, which is critical for the success of the stent. With this technology, Medibrane’s team created the Sutureless Lamination method, which achieves excellent adhesion without the need for sutures.

Key Benefits of Sutureless Lamination Technology:

• Low covering thickness
• Low crimping profile
• Fully automated process
• Faster manufacturing time
• Reduced friction during delivery

Ideal Applications for Sutureless Lamination of Fabric:

• Heart valves
• Abdominal aortic aneurysm vascular stents
• Non-vascular stents
• Left atrial appendage implant
• Acute heart failure devices

Specifications:

• Available in single or double layers (inner diameter or both inner and outer cover layers)
• Wall thickness range: 60 – 200 µm
