Braided Catheter Shaft

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.
