A design-centered workflow
See how construction choices shape performance.
Define the catheter architecture and evaluate mechanical characteristics early, while the design is still easy to change.
Evaluate the mechanics
Analyze flexural, axial, and torsional rigidities, kink radius, tensile limits, and pressure-related performance.
See the engineering basis →Refine with purpose
Compare construction changes and prepare clearer design inputs for prototyping, testing, and manufacturing.

Process-aware modeling
Layers can interact during manufacturing.
Adjacent polymer layers may blend during processing instead of remaining perfectly independent. CathCAD® models composite behavior with this manufacturing reality in mind.
Its validation is tied to physical catheter designs and measured behavior. The work captures catheter processes and connects analysis to real constructions.

Materials & data
Shared material inputs. Customer-controlled designs.
CathCAD connects to cloud-hosted material and braid-wire data. Each customer firm has a company-specific library shared by its licensed users, helping teams work from consistent modeling inputs.
Customer catheter designs are not stored in the cloud unless the customer explicitly authorizes it.

CathCAD®’s Composite Laminate Model
CathCAD®’s composite laminate model was developed and is owned by Roth Technologies. Its founder holds a Ph.D. from Georgia Tech, with academic minors in mechanics of materials and mathematics, and has more than ten patents.
That expertise is applied to the realities of catheter construction: material behavior, reinforcement, layer interaction, and manufacturing processes. The model is evaluated against physical catheter designs and test data.
