Abstract

An optical working shaft system. The system includes a working shaft for insertion into a working tube of at least one of an endoscope and a catheter. The working shaft has a distal end defining a distal area in a vicinity thereof, and further includes: a device for radiating optical beams through the distal end; and a fluid for scattering the beams at least in the distal area. The fluid is operatively associated with the device for radiating such that, at least in the distal area, a path of the beams extends inside the fluid, the fluid further being effective as a coolant for removing waste heat generated by a scattering of the beams in the distal area.
