The present invention generally relates to medical systems and apparatus and uses thereof for treating obesity and/or obesity-related diseases, and more specifically, relates to systems and methods for energy recovery in a laparoscopically-placed gastric banding system operably coupled to a piezo actuator. The energy recovery may be obtained utilizing an energy recovery device, such as an inductor, coupled to the piezo actuator. The energy recovery device may utilize two circuits to facilitate energy recovery, and the two circuits may include diodes with opposite orientations to control current flow.
