The device for interstitial laser thermotherapy of tumors comprises an hollow needle ( 3 ) with a point ( 3 A) for perforating a tissue (T) to be treated, and a light guide ( 9 ) which can be inserted in said hollow needle. The hollow needle is associated with a membrane ( 17 ) which is inflatable to form a balloon (P) into which the distal end ( 9 A) of said light guide ( 9 ) can project, the membrane being inflated to create a cavity in the tissue to be treated into which laser radiation is guided by said light guide.
