Devices, systems, methods and kits are provided for endoscopically accessing a body cavity and providing a directed pathway toward a target tissue within the cavity. The directed pathway is provided by a multi-catheter guiding system which is positioned in a desired configuration, generally directed toward the target tissue. Interventional devices may then be passed through the guiding system to the target tissue. Depending on the location of the target tissue and the desired angle of approach, the guiding system may be required to maintain one or more curves in one or more planes to properly direct the interventional devices. The multi-catheter guiding system of the present invention comprises an outer guiding catheter and a coaxially positioned inner guiding catheter, each of which independently form curvatures so that together the curves properly direct the interventional device.
