Cardiovascular and Neurovascular device manufacturers continue to innovate the surfaces of implants for improved clinical performance, enhanced therapeutic action, and market differentiation.
The innovation can be achieved through changing materials, functionalizing surface chemistries, applying coatings, or employing processing treatments, to name a few. However, as with any innovation, challenges can arise – e.g. poor coating adherence on the surface of neurovascular stents; inconsistent pharmaceutical active loading on the surface of drug coated cardiovascular balloons; or pitting corrosion on the surface of overlapping stents. These are just a few of the many challenges encountered in the industry. As we collaboratively work to root-cause issues, optimize processes, and implement corrective actions, visualizing and quantifying surface chemistries and morphologies is paramount. This webinar, presented by Ursula Thompson, explores various surface analysis techniques used to achieve these aforementioned goals.
Surface analysis techniques measure the chemical and physical composition of the outermost atomic layers of a material. With any manufactured item there is always a surface and this behaves very differently to the bulk.
In this webinar, we look at measuring the factors controlled by surfaces, including: cleanliness, adhesion strength, wear performance, biocompatibility and optical properties, amongst others; and look at the key questions that surface science helps us to answer:
