Abstract: Provided is an endoluminal device system including: an elongated and flexible endoluminal device; a wire that is disposed in the endoluminal device; a first sensor that detects tension of the wire; a second sensor that detects displacement of the wire; a driving device capable of pulling the wire; and a processor. The processor is configured to: cause the driving device to execute a relaxing operation for relaxing the wire, acquire the tension and the displacement of the wire during the relaxing operation, which are detected by the first sensor and the second sensor, respectively, and adjust a control parameter of the endoluminal device based on a rate of change in the tension with respect to the displacement.

Abstract: A medical system includes an endoscope configured to include an insertion portion inserted into a body cavity, a drive device configured to be detachably connected to the endoscope and electrically drive the endoscope, and a controller configured to be communicably connected to the drive device and to which an operation for electrically driving the endoscope is input, in which the insertion portion includes a first joint and a second joint configured to be independently driven and controlled by the drive device based on the operation input to the controller.
