Stent Design & FEA
Stent Design
- Prototyping, Solid Modeling, Engineering Drawings
- Finite Element Analysis (FEA) for stress and fatigue analysis, virtual experiments, including regulatory submission support & consulting
- CFD (Computational Fluid Dynamics) to analyze blood flow and sheer force through the stent and optimize stent design according to desired hemodynamic parameters
- Multivariate analysis of critical design features
- Design refinement and prototyping
- PRS (Product Requirement Specifications – Engineering specifications), solid models, and tooling
- Process development and optimization
- As an extension of your R&D department, we can provide technical support during stent design and development process
Stent Optimization
- At Cardiomed Technology, we can not only design new stents and analyze existing designs but also optimize any stent design to reach the optimum combination of stent design parameters such as radial force, scaffolding, equivalent pressure, axial flexibility, bending flexibility, fatigue resistance etc, thus achieving the best stent performance during the clinical use.
- Most commercially used stents are not optimized to achieve the optimum combination of design parameters as thorough calculations and optimization are otfen absent in the design process.. At Cardiomed Technology we take a great pride in the ability to provide our clients with optimum designs, thus ultimately benefiting many patients worldwide.
Stent Performance Improvements
- At Cardiomed Technology, we take a great pride in the ability to redesign the existing stents that have exhibited cerain flaws during the clinical use in order to optimize their clinical performance
- Redesign projects are usually handled by first determining the baseline for all stent design parameters, performing calculations to optimize/improve stent performance, creating the engineering drawings of improved design, fabricating the improved design, and finally performing the bench testing to confirm the performance improvements predicted by theoretical calculations.
