(EN) HIGH-FREQUENCY HEATING BALLOON CATHETER
(FR) SONDE A BALLONNET DE CHAUFFAGE PAR HAUTE FREQUENCE
Abrégé
(EN)
A high-frequency balloon catheter in which vertical temperature difference due to convection heat in the balloon can be eliminated surely and an affected part can be subjected to thermotherapy in safety by heating a tissue touching the balloon uniformly at an optimum temperature. The high-frequency heating balloon catheter is characterized by comprising a catheter shaft (3) consisting of an outer tubular shaft (1) and an inner tubular shaft (2), a balloon (4) located between the forward end part of the outer tubular shaft shaped to be able to touch a target lesion part (41) under expanded state and the vicinity of the forward end part of the inner tubular shaft, a high frequency conduction electrode (6) arranged in the wall of the balloon capable of transmitting high frequency power or in the balloon, a lead wire (7) being connected electrically with the high frequency conduction electrode, a temperature sensor (8) capable of monitoring a temperature in the balloon, and means (12:16, 20) for forming an eddy by whirling fluid introduced into the balloon vertically such that vertical temperature difference in the balloon due to convection heat is eliminated.
