Abstract
A microwave ablation device including a cable assembly configured to connect a microwave ablation device to an energy source and a feedline in electrical communication with the cable assembly. The microwave ablation device further includes a balun on an outer conductor of the feedline, and a temperature sensor on the balun sensing the temperature of the balun.
Claims28
A microwave ablation device comprising:
- a cable assembly configured to connect a microwave ablation device to an energy source;
- a feedline in electrical communication with the cable assembly;
- a balun disposed on an outer conductor of the feedline,
- a temperature sensor disposed on the balun sensing the temperature of the balun.
1 more element
A microwave ablation device, comprising:
- a handle assembly fluidly enclosing a portion of a microwave feedline and a cooling assembly;
- a tubular member extending from the handle assembly and enclosing a distal portion of the feedline and the cooling assembly, the distal portion of the feed line terminating in a radiating section and the distal portion of the cooling assembly configured to cool the radiating section;
- a flexible cable assembly connected to the handle assembly and enclosing a proximal portion of the feedline, the flexible cable assembly configured to connect the feedline to an energy source;
- and
- a temperature sensing system associated with the cable assembly and configured to sense a temperature profile of tissue surrounding the distal radiating end of the tubular member.
