I agree with @bb254 and @asimbana about the INC choice over LLC and would like to add more on the CONS. The biggest drawback is the double taxation (C Corp). Also, shareholders that control and own a significant amount, or majority, of the corporation’s voting stock have a dominant voice in the management of the business in comparison to shareholders that do not own as much stock. For a medical device company, it may not be great but I don’t think it’s a major drawback.
