CathCAD®

CathCAD® includes a comprehensive materials and braid wire database hosted on a MySQL server. The base materials library includes 24 materials including Polyimide, PTFE, PEEK, FEP, ETFE, PeBax, Polyurethanes, and Polyethylene (LDPE, MDPE, and HDPE). The software will model Extrusion AND Film Cast materials as well as combinations, that is, the software modelling capabilities are process independent.

The base CathCAD® outputs include flexural (EI), longitudinal (EA), and torsional rigidities (GJ).

FAILURE MODE ANALYSIS

The software computes the buckling kink radius as well as the elliptical shape of the lumen at a given bend radius. CathCAD® V2.0 (released June, 2013) includes estimates of tensile strength, torsional stiffness, burst pressure, as well as an improved kink radius algorithm suitable for use for thicker wall composite tubing.

CUSTOMIZE

An individual materials and braid wire database are created for your firm. Our CathACCESS® software utility program allows you to easily add/subtract/modify items in the materials database to meet your specific design requirements.

VALIDATION

The CathCAD® Software has been validated and a summary of the validation protocol is available.
