Successfully developing new medical devices, including minimally invasive technologies, is heavily dependent on addressing an appropriate clinical need, “Get [the clinical need] right and you have a chance, get it wrong and all further effort is likely to be wasted” [1], p. 3. While formalized methods, such as ethnographic research, can be effective when applied to medical technology development, less formal and potentially less effective methods are reported as commonly used [2,3] due to constraints on user accessibility and other factors [2,4]. These informal methods include processes such as “informal expert review,” where input on clinical needs is primarily generated through the involvement of a small number of experts [3].

However, studies of unmet needs in nonmedical applications have demonstrated that users with varying levels of expertise are equally likely to submit a...
