The customer is a leading innovator in advanced energy medical device design and manufacturing. The company delivers unique energy solutions for cosmetic surgery and medical technology applications. In particular, they have developed plasma-mediated ablation technology that is highly focused and thus causes negligible heat transfer or damage to surrounding tissues, which improves patient outcomes and physicians’ experiences. They needed a shaft for the product that would be flexible and have a high dielectric strength. And since the shaft is being used in an electrosurgical tool, all of the materials had to be biocompatible. Though stainless steel has some of the necessary features, such as rigidity and ease of assembly, it wasn’t suitable for this application because of the required dielectric strength.
