**11. Conclusions**

Anti-obesity medical devices represent a heterogenous family of devices in terms of presentation, usage/administration, mechanism of action, effectiveness, safety, regulation, availability, and cost. They offer an attractive approach in managing obesity. Anti-obesity medical devices are positioned to bridge the gap between more conservative treatments (e.g., lifestyle) and more aggressive interventions (e.g., bariatric surgery). Their use should always be combined with lifestyle changes.

Considering the large market size of obesity treatment and the small percentage of subjects treated with drugs or bariatric surgery, anti-obesity medical devices can play a major role in the management of obesity.
