Implantable Medical Textiles

Aran - Woven Medical Fabrics

Woven medical fabrics are made up of interlacing yarns which cross one another at right angles. The weft yarns run transversely across the loom, with the warp yarn running longitudinally, creating a dimensionally stable implantable fabric. This implantable fabric configuration results in a flexible material with desirable performance attributes applied, such as high tensile strength, high suture retention, and a high level of burst strength. When compared to knitted fabric this material can be manufactured to be comparatively thinner, with a smaller pore size. This is usually applied where the fabric is required to act as an impermeable barrier.

Aran - Knitted Medical Fabrics

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.
