Selecting optimal coating(s) for wire-based components incorporated into medical devices can be a challenging task for even the most experienced design team due to the numerous and everchanging options promoted in the marketplace.
In the recorded webinar made by the leading engineers at Sandvik different polymer coating material types will be reviewed with respect to general properties and other primary reasons for selection based on the application or process considerations. The webinar showed that 60% felt that finding the right coating is the most challenging step in the design process in order not to enconter failurs further down in the manufacturing process.
Sandvik Palm Coast's production unit offers more than forty (40) different polymer based stand-alone dip coating options which in many cases are combined to formulate a customer focused solution. Information available from brochures or digital media platforms offers some insight into options available to the product designer. However, product performance, manufacturability and cost considerations are usually not as well defined. In general, polymer coatings are applied to metal/alloy wire for medical devices to provide either electrical isolation for signal/power transmission, a lubricious surface layer for reducing tissue damage and patient trauma and/or enhance the biocompatible nature of the wire-based component.
Further processing is required to convert the coated wire into an active component in the device. Downstream operations can include forming operations such as coiling that add mechanical stress to the material system, selective coating removal for electrical connectivity and stranding to improve the flexibility of the overall lead system among other downstream processes. In order to select the optimal coating for the operation, it is critical to understand the follow-on procedures.
The discussion in the webinar will be limited to dip coating polymer materials vs other techniques such as extrusion or spray coating. Some generalized case studies will be included to help explain the method that has been useful to define the final polymer coating options.
The goal for this webinar is to share our experience with those that are keen to learn more about the key interactive parameters that can help drive a better product design decision to get reliable long-time use of the products.
