Custom Manufacturing Technologies for Medical Braids and Nonwoven Felts


Advantages of Biomedical Textiles for Use in Implantable Medical Devices
BraidsNonwoven Felts for Medical Textiles

It takes advanced capabilities to develop today’s highly technical medical devices. At US BioDesign, our teams of experienced engineers and technicians work closely with leading medical device companies to develop implantable devices that incorporate biomedical textile constructs.

US BioDesign Core Technologies for Biomedical Textiles

Medical Braiding, including Nitinol Braids and Micro-Braiding

Braided structures are often integral to the design of minimally invasive cardiovascular sports medicine and neurovascular medical devices. When designing a braided structure, it is essential to consider many factors such as catheter size, radial force, radiopacity, long-term or short-term use, etc. These are details that our engineers will discuss with you when designing a unique braided structure specifically for your product.

The materials we use in our braided structures may be strong and relatively easy to work with, or extremely delicate and difficult to handle. In some cases, individual strands are so fine it is nearly impossible to see them. Some material is also very expensive. Material handling during production is critical to product quality and cost efficiency. Our technicians are trained in optimal handling methods for each of the specialty materials and equipment we use.

At US BioDesign, our technicians undergo rigorous training to gain the experience and deep knowledge necessary to work with biomedical textiles. Most of the manufacturing equipment that we use to produce our braids is designed or modified to our specifications and needs. In fact, one of our medical braiders is the largest of its kind in the world.

Custom Manufactured Nonwoven Medical Felt

Weaving, braiding and knitting technologies have been around for centuries. The technology to create “nonwoven” felted fabrics from short yarn fibers is relatively new – and highly technical. Our process for manufacturing nonwoven felt involves multiple pieces of specialized equipment which create an interlaced web of short fibers. A Needle Loom entangles the fibers to form the felted fabric. Our equipment has been designed and customized by our engineers to specifically manufacture fabrics for medical use. As an added protection from potential contamination, every contact point in our process where fiber meets metal is stainless steel.

Nonwoven medical felts made from Polyester or Teflon are often used to protect soft tissues from damage that may be caused by sutures in or near the tissue. Other uses may include scaffold structures used for regenerative tissue engineering.

We take pride in the fact that US BioDesign manufactures its PTFE felt in the United States from 100% certified, biocompatible PTFE fiber, which makes US BioDesign the number one choice for medical device companies who prefer American-made materials.
