Abstract: Minimally invasive medical treatment using catheters is the path that the healthcare industry is being gradually coerced into for minimizing patient trauma, procedural time, infection rate and the recovery time. The design development of the catheters is an iterative process to accurately translate the physician user needs to mechanical performance. CathCAD? software helps the catheter designer to theoretically evaluate catheter design input parameters related to polymer jacket material, thickness, braid pattern type, braid configuration to mechanical performance outputs such as flexural, torsional, and tensile rigidities with minimal spending of time, human and capital resources.
