Abstract
In one embodiment of the invention, an apparatus for performing surgical procedures is disclosed including a flexible entry guide tube, and a first steering device. The flexible entry guide tube has one or more lumens extending along its length from a proximal end to substantially at or near a distal end. At least one of the one or more lumens is an instrument lumen with open ends to receive a flexible shaft of a surgical tool to perform surgery near the distal end of the flexible entry guide tube. The first steering device is insertable into the instrument lumen to shape the flexible entry guide tube as it is inserted through an opening in a body and along a path towards a surgical site. The apparatus may further include a flexible locking device to couple to the flexible entry guide tube and selectively rigidize the flexible entry guide tube to hold its shape. The flexible entry guide tube may be steered by remote control with one or more actuators.
