Project Overview

The RF generator is used for delivering algorithm-controlled RF energy to proprietary surgical devices. The RF Generator in conjunction with surgical devices provides the physician with the capability for non-invasive volumetric tissue reduction of the palate. ZoZo Engineering worked closely with the customer’s executive staff and marketing group to identify and produce the right product for the market. ZoZo Engineering was responsible for all aspects of the product development including coordinating internal customer resources.
