Claim 0:
1. An endoscope, comprising:
a substantially rigid elongate body at least partially insertable into a kidney of a patient,
the elongate body including a visualization channel that extends through the elongate body from a proximal end of the elongate body to a distal end of the elongate body;
an elongate viewing instrument configured to advance distally and retract proximally through the visualization channel of the elongate body, and
a moveable actuator coupled to a proximal end of the elongate viewing instrument and located proximal to the proximal end of the elongate body, the moveable actuator being advanceable distally toward the elongate body to distally advance the elongate viewing instrument and retractable proximally away from the elongate body to proximally retract the elongate viewing instrument,
the elongate viewing instrument extending distally beyond the distal end of the elongate body when the elongate viewing instrument is fully advanced distally,
the elongate viewing instrument including a distal portion that extends beyond the distal end of the elongate body to a distalmost end of the elongate viewing instrument,
the distal portion being entirely pre-biased to assume a generally circular curved shape when the distal portion is unconfined, such that the distal portion of the elongate viewing instrument is configured to curve when the distal portion of the elongate viewing instrument is advanced distally to exit the visualization channel and configured to generally straighten when the distal portion of the elongate viewing instrument is retracted proximally to enter the visualization channel,
a distal end of the elongate viewing instrument further including a light port that is configured to illuminate a target and provide an image of the illuminated target.
