Abstract: Systems and techniques for endoscopically-assisted percutaneous medical procedures are described. Techniques can include inserting a first medical instrument having an elongated shaft and a first position sensor into a region of anatomy through a natural orifice. A first position of the first medical instrument within the region can be determined with the first position sensor. A target location can be defined within the region based on the determined first position. A second medical instrument can be percutaneously guided toward the target location. The techniques can be implemented with a robotically-enabled medical system.
