Video learning library

Build your catheter modeling skills.

Explore CathCAD® workflows, composite tubing mechanics, test methods, and specialized modeling tools through these training videos.

In-house engineering seminar

Catheter design and analysis training, grounded in engineering mechanics.

CathCAD® is the industry’s leading design and analysis software suite for catheter shaft engineering. Developed by Roth Technologies, the software helps catheter design engineers rapidly model, simulate, and optimize multilayer catheter constructions, with real-world predictive capability.

In-house seminars combine instruction in CathCAD® tools with the key principles of Mechanics of Materials and Composite Laminate Theory. Participants learn to navigate the software, interpret results, and apply CathCAD® outputs directly to catheter design workflows.

One day. Eight hours. Real catheter engineering.

Led by CathCAD® founder Ronald Roth, Ph.D., the seminar delivers a full day of direct instruction and discussion grounded in real catheter designs, test methods, materials, and modeling decisions.

Training includes

  • Multilayer shaft modeling with combinations of liners, jackets, polymers, braids, and coils
  • Braid and coil geometry, including coverage, angle, wire count, and mechanical performance
  • Stiffness, column strength, and bending predictions using Mechanics of Materials algorithms
  • Torque, kink resistance, and tensile behavior estimation using physics-driven models
  • Rapid design iteration for R&D, manufacturing, and regulatory justification
  • Core instruction in Mechanics of Materials and Composite Laminate Theory
Typical learning modules
  1. Mechanics of Materials Fundamentals for Catheter Engineers
  2. Stress/strain, deflection, stiffness, bending radius, and column strength
  3. Catheter testing fundamentals: torque, pushability, kink, tensile, burst, leak, and fatigue
  4. Material selection for liners, jacketing, braid and coil reinforcement, and polymers
  5. Braid and coil coverage, geometry, and performance tuning
  6. CathCAD® Standard, Advanced, and Multi Lumen software tools
  7. Case studies based on real CathCAD® design projects
