Microwave energy-delivery device and system

摘要

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.

主权项

1. A microwave probe assembly, comprising:
a hub having a proximal end and a distal end and at least two ports; a hub cap sized to be received in a distal end of the hub; an antenna transition assembly sized to be received in the proximal end of the hub; a hub divider sized to be received between the hub cap and the antenna transition assembly and forming a first and a second chamber; an inner tubular member received within a lumen of the hub divider; and a metal cylinder located columinally within inner tubular member and promoting a seal between the hub divider and the inner tubular member separating the first and second chambers.
