A1
Abstract:
A lung cancer treatment catheter characterized by including shaft (10) provided with flexible distal part (10a) and proximal part (10b) disposed nearer to the proximal end than the distal part and having rigidity higher than that of the distal part, the shaft (10) having a lumen formed through the distal part and proximal part; electrode (9) fitted to the distal part of the shaft; temperature sensor (12) disposed in the vicinity of the electrode; and conductor wire (11) drawn through the interior of the lumen and having its one end connected to the electrode. Further, there is provided a method of lung cancer treatment using this catheter. The lung cancer treatment catheter can reach the periphery of the bronchi, and can be disposed in a treatment site under observation in combination with an endoscope, and can cauterize the lung cancer cells by high-frequency current passage.
