1. A system comprising a catheter having a kink sensor, the kink sensor comprising at least one optical fiber,
wherein the kink sensor further comprises an evaluation device configured to be attached to the at least one optical fiber, and to determine, based on a first measurement of a quantity of light transmitted into the at least one optical fiber and a second measurement of a quantity of the light that is reflected back to the evaluation device over the at least one optical fiber, that a portion of the light is getting coupled out of the at least one optical fiber along a length of the at least one optical fiber.
