Microwave ablation catheter and method of utilizing the same
First Claim
1. A microwave ablation system, comprising:
- a microwave energy source;
a microwave ablation catheter including a coaxial cable having a proximal end portion and a distal end portion, the coaxial cable adapted to be connected at its proximal end portion to the microwave energy source, the coaxial cable including a distal radiating section disposed at its distal end portion, the coaxial cable further including inner and outer conductors and a dielectric positioned therebetween, the inner conductor extending distally past the outer conductor in sealed engagement with the distal radiating section, the outer conductor having a braided configuration and being configured to facilitate movement of the microwave ablation catheter through a branched luminal network of a patient;
a plurality of acoustic sensors positioned in airways proximate target tissue; and
a controller configured to measure a tissue property based on data received from the plurality of acoustic sensors.

Abstract
A microwave ablation catheter is provided. The microwave ablation catheter includes a coaxial cable connected at its proximal end to a microwave energy source and at its distal end to a distal radiating section. The coaxial cable includes inner and outer conductors and a dielectric positioned therebetween. The inner conductor extends distally past the outer conductor and is in sealed engagement with the distal radiating section. A balun is formed in part from a conductive material electrically connected to the outer conductor of the coaxial cable and extends along at least a portion of the coaxial cable. The conductive material has a braided configuration and is covered by at least one insulative material.
