Embodiment Construction

[0073]Methods and apparatuses for advancing an elongate, flexible medical device (such as a catheter, guidewire, or the like) are described. In particular, described herein are apparatuses (e.g., devices) for advancing an elongate flexible medical device that include a pair of one-way gripping valves that are connected by a pair of arms and a hinge region. Moving the flexible arms (e.g., bending at the hinge region) may reciprocate the first and second one-way gripping valves (which, for convenience, may be referred to herein as simply ‘valves’). The one-way gripping valves are configured to allow an elongate flexible member (such as a catheter) to move in a first direction through an opening (e.g., a channel) of the one-way gripping valve, while preventing the elongate flexible member from moving in a second direction that is opposite from the first direction. The hinge region may be configured to allow the first arm to move relative to the second arm to reciprocate the one-way gri...
