AranKnitted Medical Fabrics

SHARE
Knitted medical fabrics offer unique performance criteria when compared to textiles processed by other means. Specifically, knitted fabrics offer compliance and the ability to negate unravelling of yarns.  Where a knitted fabric is implanted can dictate particular compliance characteristics, to ensure that the material stretches or conforms with the movement of the body, limiting unwanted stresses or discomfort.  Aran Biomedical uses digitally controlled equipment to precisely define specific knit configurations and pore geometries that offer preferred compliance characteristics in the X (machine) and Y (transverse) directions.  This also applies for tubular fabric, where the degree to which a fabric stretches radially and longitudinally can be precisely tuned.

Aran Biomedical can provide knitted medical fabrics with the following design configurations:

  • Warp knit: Flat & Tubular
  • Circular knit
  • Spacer knit
  • 3D Shape Formed Fabrics

The other benefit of knitted fabric with defined compliance characteristics is that the material can conform to the geometry of underlying implantable frames, so rather than folding during crimping and deployment, the material can stretch and foreshorten.
