Braiding improves the functionality of a catheter shaft by improving kink and pressure resistance and increasing the mechanical properties of a tube all while maximizing the working area of a tube. Braided reflow shafts can be designed to provide a combination of different performance characteristics. Properties that can be tailored and varied over the length of the catheter shaft include:

  • Flexibility
  • Kink resistance
  • Pushability
  • Torque transmission
  • Burst strength
  • Column strength


Vesta uses dedicated extrusion, braiding and reflow equipment to manufacture its braided shafts. Shafts can have a single or multiple durometers along the shaft or the braid pattern can be varied to change the stiffness of the shaft along the length. Customers typically employ braided construction where the application requires high pressure resistance or requires navigation thru small and tortuous anatomies, such as small blood vessels in the heart or brain. Vesta’s braiding capabilities include:

  • OD ranges from 0.030” – 0.320”
  • Round wire, flat wire and fibers
  • Constant or variable pick pattern
  • Single or variable durometer
  • PTFE lined
  • Braid to coil transition
  • Cut to length or spooled
