DEVICES AND METHODS FOR THERAPEUTIC HEAT TREATMENT

摘要

Methods and devices (e.g., for nerve modulation) may include at least one thermistor and a balloon having a balloon wall. In one or more embodiments, the medical device is configured and arranged to transfer heat to the medical device surroundings. In one or more embodiments, the at least one thermistor is a portion of a thermistor array disposed on the balloon wall, the thermistor array including a plurality of thermistors and operatively engaged with a source of electric current. In one or more embodiments, the device includes at least one flexible circuit mounted on the outer surface of the expandable balloon, the at least one flexible circuit including at least one temperature-sensing device that includes at least one thermistor, wherein at least a portion of a conductive layer is electronically coupled to the thermistor, with the proviso that no electrode is associated with the conductive layer.
