Abstract: An apparatus comprising a plurality of electrically conductive elements for transmitting an electrical signal from a sensor to a medical device is described, wherein the electrically conductive elements are moveable between a first stored position and a second in use position. In this manner the apparatus provides an interface between the sensor and the medical device such that the length of each of the electrically conductive elements can be varied and adjusted such that the excess amount of the elements is minimized and the functionality of the sensors and/or medical device maximized.
