Abstract
The present invention provides devices, systems, methods and kits for endoscopically accessing a body cavity and providing a directed pathway toward a target tissue within the cavity. The directed pathway is provided by an access sheath which is positioned in a desired configuration, generally directed toward the target tissue. Depending on the location of the target tissue and the desired angle of approach, the access sheath may be required to maintain one or more curves in one or more planes to properly direct the interventional devices. In addition, the access sheath has a locking feature to hold the sheath in place and maintain the desired configuration. Interventional devices may then be passed through the sheath to the target tissue.
