Abstract: Various aspects of the present disclosure are directed to apparatuses, systems, and methods that may include a magnetic drive system of a blood pump. The magnetic drive system may include an impeller, a drive shaft, a driven magnet assembly, a driving magnet assembly, and a flux enhancer.

Abstract: 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.

Abstract: An expandable balloon catheter having an elongate shaft having a distal end region and an expandable balloon coupled to the distal end region of the elongate shaft is disclosed. One or more cutting members are attached to the expandable balloon, wherein at least a portion of each of the one or more cutting members comprises a Curie material having a Curie temperature between 60° and 400° Celsius.
