Complex Medical Braiding and Formed Biomedical Structures

Our deep expertise specializing in nitinol/wire braiding and post-processing of braided constructs brings unmatched knowledge and innovation for lifesaving biomedical structures, medical fabrics, and custom materials. We provide a full range of complex medical braiding solutions to meet your exact requirements. With equipment capable of producing braids from 3 up to 288 ends. Take advantage of our variable braiding technology offering complete versatility from 3 carrier to 96 carrier ends, with independent placement and control for each individual carrier. This system enables highly accurate, repeatable structures and advanced braid configurations such as bi-furcations, seamless transitions from solid to tubular to flat, atraumatic ends, coils and overbraids. Devices can be heat set and shape formed to preferred dimensions, with the option for further downstream processing, such as coating, if needed, to enable particular functionality. We will work with your engineering team to develop the perfect custom braided or shaped device for your unique application, helping you get to market faster

Implant Design Manufacturing Overview Video

Our biomaterial focused solutions for medical implants service a broad range of product development solutions for Vascular, General Surgery and Orthopaedic implants. Our capabilities are structured on the following core technologies: Medical Textiles, Implant Coating Solutions, Biomaterial Frame Encapsulation, as well as Resorbable Implantable Solutions. This is supported by a suite of finishing and assembly capabilities to offer a full-service product development solution, from concept design and development, to rapid prototyping, regulatory support and volume cleanroom manufacturing.

  • Horizontal Braiding - 8 to 288 carriers
  • Flat Braiding - 3 to 31 carriers
  • Flat to Round Braiding
  • Cable Braiding - 3 to 16 carriers 
  • Variable Braiding - e.g. Bi/ Tri Furcation - 3 to 96 ends
  • Cable Braiding
  • Net shaping of Nitinol Braids

Integer’s suture offering extends beyond standard round braided sutures (USP 2 down to USP 7-0).Custom sutures are developed in response to customer’s design inputs, incorporating seamless flat-to-round transitions, smooth tapers, loops and bifurcations, and porous architecture.

Suture clinical performance is tailored using appropriate material grade and textile design, leveraging Integer’s Textile Design Engineering expertise. Sutures are produced using implantable grade fibres of UHMWPE (e.g. Dyneema Purity), polyester (PET) and polypropylene (PP), as well as nitinol and resorbable polymers (e.g. PLGA).

High Strength Tapes, Bands, Tethers & Cables

Integer develops ultra-high strength textile implants, to meet the particular requirements of individual clinical applications. For example, densely woven and braided UHMWPE and nitinol constructs offer the tensile strength and stiffness required, whilst ensuring the supple smooth drapability required of an actuation cable, tether, cerclage tape, or load-bearing tissue repair implant.For device actuation polymeric cables, can be designed to offer high-strength per relative size along with <1% elongation, making them a preferable alternative in some cases to metal actuation cables and wires.

The material used in a braided device is one of the numerous variables that affect the mechanical properties of the braid. For medical braiding we can use a wide range of round and flat wire, such as:

  • Nitinol#l
  • Nitinol#3
  • Nitinol#9
  • DFTWire
  • SS
  • Tungsten
  • Platinum

We also offer substrate micro fine wire for implantable devices. These high-density braids are made from ultra-fine wire and polymers and can be as low as <0.001" (25 micron). This low-profile wire braiding capability enables the production of braids with minuscule pore sizes, necessary for next generation braided cardiovascular devices.

High Precision Elastomeric Coatings

These are often added to the braid to create an impermeable barrier. The barrier can also eliminate tissue adhesion to an implant, or contain material, such as thrombus, emboli or ureteral stone fragments. Thickness can be as low as 5µm.

Secondary Shape Setting

This is a technique used to achieve more complex shapes, such as domes, discs and prolapsed designs. These dimensional changes, significantly alter the mechanical properties of the braid, which can help reduce implant migration for example.

Wire Welding

This is a process employed to either secure wire ends or facilitate subsequent braid assembly. In securing the ends, wires can be welded together and possibly secured to a marker band or looped to create an atraumatic end.
