Abstract: A microwave ablation probe includes a cable extending in an axial direction and also includes an antenna configured to deliver Radio Frequency (RF) energy. The probe includes a shell positioned radially outward of the cable and a choke electrically coupled to an outer conductor of the cable. The probe also includes a cooling tube positioned inside the shell and positioned radially outward of the cable. The cooling tube including a first portion with a first outer diameter and a second portion with a second outer diameter. The second portion located radially outward of the choke and the second outer diameter being greater than the first outer diameter.

Abstract: An intraluminal sensing device includes a guidewire configured to be positioned within a body lumen of a patient. The guidewire includes a core wire, a first insulative coating covering at least a portion of a circumference of the core wire, and at least two conductive traces insulated from one another and extending longitudinally along at least the portion of the length of the core wire over an outer surface of the first insulative coating. Each conductive trace conforms to the curvature of the first insulative coating. The guidewire also includes a second insulative coating covering the conductive traces along at least the portion of the length of the core wire, and a sensor in electrical communication with the at least two conductive traces and configured to obtain physiological data while positioned within the body lumen. The guidewire also includes a proximal connector in electrical communication with the conductive traces.
