Engineering approach

Model the catheter as it is designed and made.

CathCAD® brings composite mechanics, catheter construction, and observed physical behavior into a purpose-built design workflow.

Proprietary composite model

Developed and owned by Roth Technologies.

CathCAD® uses a proprietary composite laminate model developed and owned by Roth Technologies. The model applies engineering mechanics to the construction of composite catheter tubing.

Its design inputs describe the assembled structure—materials, reinforcement, geometry, and construction—not a generic tube standing in for a catheter.

Physical design validation

Validation tied to catheter designs and measured behavior.

CathCAD® validation is tied directly to physical catheter designs and measured behavior. The development work has captured catheter processes and uses them to inform the model.

A

Physical constructions

Evaluate defined catheter constructions and compare modeled characteristics with measured results from physical designs.

B

Manufacturing matters

Layers may blend during processing rather than remaining independent. CathCAD® models this behavior in its composite representation.

C

Design iteration

Use the model to explore construction changes and guide engineering decisions alongside prototype testing.

Composite layer behavior

Layers do not always act independently.

In a manufactured composite tube, adjacent material layers can mix or blend. Treating every layer as an isolated, independent sheet may not reflect the finished construction.

CathCAD® accounts for this behavior as part of its catheter-focused composite modeling approach.

The model represents engineering behavior of the defined construction; final device performance still requires validation against the customer’s design requirements and physical testing.
Materials & customer data

Consistent material inputs. Customer-controlled designs.

Company-specific libraryEach customer firm has its own material and braid-wire database.
Shared within the firmLicensed colleagues at the same firm use the common company library, so local edits do not silently create divergent inputs.
Cloud-hosted material dataMaterial and braid-wire data are hosted in the cloud for access by licensed users.
Design storageCustomer designs are not stored in the cloud unless the customer explicitly authorizes it.
“CathCAD® modeling is grounded in catheter construction, manufacturing processes, and physical designs.”
