Laser-resistant guide probe for laser treatment of endoscopically impassable tumour stenoses.
A laser-resistant guide probe that can be placed endoscopically, for use in the laser treatment of impassable tumour stenosis is described. It meets the necessary requirements such as low level of absorption of YAG laser light (1,064 nm wavelength), high thermal stability and low heat conduction. So far, the probe has been used complication-free, in four patients.
