A device for applying an aneurysm clip includes a novel lockable steerable endoscope (12), having steering mechanism (14), and a novel surgical device for applying the clip including an applicator (22) for the clip (24) comprising a remote actuator in the form of a flexible shaft (44) inside a flexible conduit (42), both running inside the endoscope, and jaws for holding the clip at the distal end of the shaft. The endoscope is steered to the site of the aneurysm and locked in position. The applicator is introduced into the endoscope, and moved to the site of the aneurysm by driving both the shaft and the conduit by drive mechanisms in the housing (20). The clip, when in position around the aneurysm, is actuated by movement of the shaft out of the conduit to open the jaws and release the clip which closes around the aneurysm.
