Abstract:
A laser application set to treat tumors comprisinga tunneled catheter (17) having a distal end and made of synthetic materials, preferably PE, FEP, PTFE, wherein the distal end of the tunneled catheter (17) is air- and fluid-tightly sealed and movably guides an optical waveguide (33), a puncturing needle (1) for performing initial penetration and for introducing of an introducer tube (6), wherein the introducer tube (6) is furnished with a closely fitting interior stylet (12) and wherein the tunneled catheter (17) is fitted with a closely fitting internal stylet (20), in which, upon removal of the stylet (12) from the introducer tube (6), the tunneled catheter (17) with the internal stylet (20) is close-fittingly inserted into the introducer tube (6) and projects from the distal end of the introducer tube (6) and in which an optical waveguide (33) is inserted after removal of the internal stylet (20) from the tunneled catheter (17).
