CathCAD for Microcatheter Design: Modeling Flexibility, Torque, Kink Resistance, and Braid Performance | Ron Roth
MedTech Unboxed: Presented by Chamfr
How can catheter teams reduce design iterations and predict performance before building prototypes? In this episode of MedTech Unboxed, Steve talks with Ron Roth of Roth Technologies about CathCAD, a software platform built to help engineers design microcatheters and composite catheter shafts using analytical models instead of trial-and-error alone.
Ron explains how CathCAD helps teams evaluate key performance parameters such as flexibility, pushability, torque, tensile strength, burst strength, and kink resistance. The conversation also covers real-world simulations, including how different liner materials, tie layers, and braid pick counts can affect catheter performance, and why that matters for today’s design decisions around PTFE alternatives, material selection, and manufacturing efficiency.
They also discuss the growth of CathCAD across the medical device industry, how close the software predictions are to actual device performance, the value of materials databases, and future possibilities such as modeling laser-cut hypotubes for more complex catheter applications. For medtech professionals in catheter design, R&D, extrusion, braiding, and device development, this episode is a practical look at simulation-driven engineering in minimally invasive device design.
