1. An endoscope having a proximal end and a distal end comprising:
- an elongated shaft having a proximal end and a distal end disposed at the distal end of the endoscope connected toan endoscope handle that is disposed at the proximal end of the endoscope,the endoscope handle having a proximal end and a distal end and an exterior, an interior, and a longitudinal axis, wherein the shaft and the endoscope handle are sealed to be liquid and gas impermeable;
optical components located at or near the proximal end of the endoscope handle;
a solid-state light source contained within the interior of the endoscope handle; and
a sealed compartment contained within the interior of the endoscope handle, wherein the sealed compartment contains at least one battery that powers a light source control circuit electrically connected to the solid-state light source.
