Paper Abstract

The interstitial laser tumor treatment and the local coagulation of malignant tumors with Nd:YAG laser radiation are approved procedures in minimal invasive medicine. The hyperthermic effects in tissue cause irreversible tissue damage. An advanced but simple disposable plastic introducer has been developed which is designed for volume coagulation by inserting a frosted bare fiber. If the desired size of the coagulation is reached, an alert signal to stop the treatment is derived from an on-line monitoring of NADH concentration by laser induced fluorescence measurements.
