摘要： A variety of medical procedures utilize two or more medical device components, including medical device components where a first medical device component is advanced within a second medical component. An example would be an elongate dilator used in combination with a guide catheter. The guide catheter and the elongate dilator may be adapted to provide a rotational lock mechanism that allows the guide catheter and the elongate dilator to lock together such that rotating one of the components causes rotation of both components. In some instances, the guide catheter and the elongate dilator may cooperate to also provide a relative axial lock between the two components.
