Braided Catheter Shaft

Braided Catheter

DTC & Partners use proprietary techniques for providing thin-walled, braided, and coiled catheters that range from 1.5F to 28F. We collaborate with you for analyzing the right balance between column strength, resilience, kink resistance, and torque response in the thinnest wall to meet the performance needs.

Catheter Shaft Technologies

  • Multi-Lumen Shafts
  • Braid to coil conversions
  • Deflectable and fixed curve shafts 
  • Multi-durometer shafts
  • Variable pitch coils and pick count braids
