Abstract: A swivel assembly can have a longitudinal axis. The swivel assembly can have an upper portion and a lower portion that is rotationally coupled to the upper portion. The lower portion can have a connector configured to securely engage a cable. The lower portion can be configured to remain in electrical communication with the upper portion as the lower portion rotates with respect to the upper portion. A motor can be disposed between the upper portion and the lower portion and configured to selectively rotate the lower portion. A sensor can be configured to detect torsion in the cable. A controller can be in communication with the sensor and the motor. Upon receiving a signal from the sensor indicating a threshold torsion in the cable, the controller can be configured to cause the motor to rotate in a direction corresponding to a direction of the torsion in the cable.

Abstract: A data transfer apparatus (“DTA”) connects to the field generator in a TTFields therapy system using the same connector on the field generator that is used to connect a transducer interface to the field generator. The field generator automatically determines whether the transducer interface or the DTA is connected to it. When the transducer interface is connected to the field generator, the field generator operates to deliver TTFields therapy to a patient. On the other hand, when the DTA is connected to the field generator, the field generator transfers patient-treatment data to the DTA, and the DTA accepts the data from the field generator. After the field generator and the DTA have been disconnected, the DTA transmits the data to a remote server, e.g., via the Internet or via cellular data transmission.
