Gain Medical is a company engaged in the research, development, manufacture and sale of medical devices, and its sales model is not direct sales. Direct sales is a sales method in which the manufacturer sells the product directly to the final consumer, bypassing middlemen and retailers. On the contrary, Gain Medical usually sells its products through channels such as distributors and medical institutions, rather than direct-to-consumer sales. This sales model better meets the specialized needs of medical devices and ensures product compliance and safety. Therefore, it can be said that Garn Medical is not a direct sales company.
