Why VirtuCath?

Stop guessing with physical prototypes. Validate your design with rigorous engineering calculations

Eliminate Prototype Cycles

A single complex prototype often costs $5,000+ and takes weeks to fabricate and test. VirtuCath allows you to evaluate hundreds of design variants digitally in an afternoon, ensuring your first physical build is based on calculated data, not intuition.

Math, Not Intuition

VirtuCath employs Classical Lamination Theory to provide rigorous analytical solutions for your composite mechanics. For complex steering dynamics, the software leverages a specialized implementation of the MuJoCo physics engine, tuned to capture non-linear catheter behavior with high fidelity.

No Simulation Expert Required

Bypass the steep learning curve of traditional FEA. The interface is built for R&D engineers, allowing you to extract actionable mechanical data like flexural stiffness and torque response without needing a dedicated simulation analyst.

Model Complex Constructions

Go beyond simple tubing. Accurately capture the mechanical interaction between liners, tie-layers, and reinforcements. Define multi-segment shafts with variable braid densities and transition zones to predict true device performance.

100% Local Execution

Your IP never leaves your hardware. The software executes strictly on your local machine with zero cloud dependency or background data transfer. Design with confidence knowing your proprietary device specifications are never uploaded, tracked, or stored externally.

Runs on Your Current Hardware

Advanced physics doesn't require a supercomputer. The solver is highly optimized for standard CPUs, delivering workstation-class performance on your existing laptop without the need for expensive GPUs or cloud compute subscriptions.

From Concept to Validation

A streamlined workflow designed to bridge the gap between initial sketch and final prototype.

01

Define Your Layup

Build your catheter section-by-section using an intuitive interface designed for engineers.

  • Layer-by-Layer Construction: Select materials from a customizable library of common polymers and apply braid or coil reinforcements.
  • Precision Control: Define exact dimensions, braid properties (PPI), and durometers for each segment of your shaft.
  • Intuitive GUI: Visualize your design in real-time as you build, ensuring every layer is placed correctly before you calculate.
02

Instant Characterization

Before you simulate motion, validate the fundamental mechanics. The catheter calculator provides immediate feedback on your design's physical properties.

  • Mechanical Outputs: Instantly calculate bending stiffness, torsional rigidity, critical buckling loads, and kink radius limits for your specific layup.
  • Visual Validation: Generate scale-accurate 3D cutaways to verify layer interactions and align your team with clear, unambiguous visual specifications.
  • Automated Reporting: Export your calculated specifications and analysis directly to PDF or Excel to drive design reviews and documentation.

Simulate Real-Time Dynamics

Powered by the MuJoCo physics engine, VirtuCath turns your static layup into a dynamic digital twin, allowing you to test performance on a virtual bench.

  • Virtual Actuation: "Drive" your catheter using on-screen controls to test deflection, tip reach, and curve shape.
  • Complex Physics: Accurately predict the curve shape across variable stiffness zones, capturing the complex interaction between different durometer segments.
  • Pre-Prototype Verification: Confirm steering range of motion and required actuation forces digitally, saving weeks of physical testing.
04

Monitor Live Telemetry

Don't just watch it move, measure it. Get a live feed of critical performance data as you actuate the device.

  • Force Feedback: Monitor real-time pull-wire tension to ensure you stay within component yield strengths and maintain ergonomic handle actuation forces.
  • Safety Margins: Compare live performance against your static limits to catch critical failures like kink radius violations in real-time.
  • Lumen Integrity: Monitor dynamic cross-sectional ovalization to ensure guide wires and delivered devices will pass smoothly through the shaft even under maximum deflection.
Live Data Analysis
05

Calculate Reflow Stackups

Instantly calculate pre- and post-reflow dimensions so you can order the right extrusions the first time without guesswork.

  • Easy Extrusion Sizing: Automatically size your raw tubing by letting the engine handle the complex volume math as thermoplastic melts through structural voids.
  • Assembly Clearances: Model dimensional tolerances across the entire stackup to confidently ensure that your specified materials can be physically assembled without interference.
  • Process Parameters: Determine the exact expanded ID and minimum shrink factor required for your chosen heat shrink to provide adequate reflow force.
06

Explore the Design Space

Run virtual Design of Experiments (DOEs) to understand the full performance landscape of your device.

  • Response Surface Modeling: Employ classical DOE methodologies to model the relationship between input parameters like wall thickness or braid density and device performance.
  • Multi-Variable Analysis: Map how changes in one layer affect the stiffness or torque response of the entire system.
  • Visual Optimization: Use generated 3D response surfaces to visually identify the "sweet spot" where performance meets manufacturability.
