Tube Forming

Tube Forming Applications

Fabricating tubing into special shapes can provide several advantages for a variety of custom designed medical products.

Uses for formed tubing include:

  • Easing assembly processes requiring alignment such as tubing connections into machines
  • Avoiding tube kinking in applications where space is constrained such as fluid management pathways integrated into handles of drug delivery catheters, and pneumatic catheter applications.  Hard or soft plastic tubing may be formed with elbows, curves, twists, double or triple bends, and coils. 
  • Facilitating the placement of interventional catheter devices to target anatomy
  • Catheter tip shapes include many standard forms that are clinically specific.  Below are examples of selective catheter shapes commonly used in vascular and radiology procedures.

Additional Tube Forming Examples

  • Braided tubing formed with 180 degree bend
  • Braided tubing formed into a coil
  • Sim-1, Cobra-2, Davis, Sim-2
  • Selective tennis racket catheter tip shape
  • Pigtail catheter tip shape
  • Curved catheter tip shape
  • Selective catheter tip shape
