When choosing a braid pattern for your project it is important to consider the pro's and con's of each. Braided tubes may be designed to bend without kinking. Minimum elongated diameter and maximum compressed diameter are often key design considerations for most medical devices.

1x1 Braid Pattern

Pros

  • Able to resist distortion to wire spacing more than other configurations
  • Stiffer sidewall than other configurations

Cons

  • More difficult to pack down into small diameter delivery sheathes than other configurations
  • Higher Production Costs
  • More liekly to kink when bent around a tight radii
  • Lower tensile strength

2x1 Braid Pattern

Pros

  • Typical pattern when number of ends match the number of braider carriers
  • Able to acheivehigher pick counts and smaller pore sizes than 1x1
  • Less likely to kink when bent around tight radii
  • Lower production costs than 1x1
  • Higher tensile strength

Cons

  • Distortion to wire spacing is more common at lower pick counts

2x2 Braid Pattern

Sometimes referred to as the "Diamond Pattern"

Pros

  • Most flexible construction in bending stiffness
  • Lower production costs than 1x1
  • Common pattern for catheter sheaths

Cons

  • When using metallic wires or monofilament polymers, the two wires within each pick will align together
  • Largest pore sizesfor similar pick desnities in using other braid patterns
