1. A medical device for use in combination with a delivery system including a lumen extending through the delivery system, the medical device comprising:
an elongate tool guide adapted to be secured relative to a distal end of the delivery system in order to guide tools extended through the elongate tool guide, the elongate tool guide movable between a deployment configuration in which the elongate tool guide is substantially parallel with the delivery system when the elongate tool guide is secured relative to the distal end of the delivery system and a working configuration in which the elongate tool guide curves away from the distal end of the delivery system
wherein the elongate tool guide comprises:
a plurality of conduit segments joined together via living hinges formed between adjacent conduit segments of the plurality of conduit segments, each of the plurality of conduit segments including at least one control aperture extending through each conduit segment; and
at least one control cable extending through each of the at least one control aperture of each conduit segment;
wherein applying an axial force to the at least one control cable causes the elongate tool guide to move between its deployment configuration and its working configuration.
