1. A probe for thermal ablation of a tissue area of skin, comprising:
- a source of thermal ablation energy;
an external shaft and a distal face plane tip;
a needle for piercing the skin and in thermal communication with said distal face plane tip for delivering thermal ablation energy; and
an external sheath surrounding at least a portion of said needle, comprising a lateral manifold with a port for delivery of a heat transfer gaseous medium.

14. A probe for thermal ablation of a tissue area located in an immediate vicinity of skin, comprising:
-
a longitudinal housing with a proximal inlet connection for electrical wires; a distal face plane tip with an outer blind hole, said distal face plane tip featuring an absorbing coating with high coefficient of absorption of radiation; a hyperthermia disposable needle positioned in said outer blind hole and comprising a pin, wherein a distal end of said pin is pointed; a metal sheath at least partially surrounding a middle section of said pin; wherein said source of thermal energy comprises a radiation source for heating, the probe further comprising a seat at the proximal end of said housing, wherein said radiation source is installed in said seat, and a concentrating lens within said housing for concentrating said energy.

17. A probe for thermal ablation of a tissue area located in an immediate vicinity of skin, comprising:
-
a longitudinal housing with a proximal inlet connection for electrical wires; a distal face plane tip with an outer blind hole; a hyperthermia disposable needle positioned in said outer blind hole and comprising a pin, wherein a distal end of said pin is pointed; a metal coil connected to said electrical wires and contacting said face plane tip for heating said pin; a metal sheath at least partially surrounding a middle section of said pin; an additional sheath for at least partially surrounding said metal sheath, wherein a gap is formed between said additional sheath and said external sheath for receiving a gaseous medium for cooling. - View Dependent Claims (18, 19)
