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 may include a flexible elongate member, a housing, and a sensor. The flexible elongate member may include a distal portion and a proximal portion and may be configured to be positioned within a body lumen of a patient. The housing may be positioned at the distal portion of the flexible elongate member. The housing may include a conductive material and a non-conductive material. The sensor may include an exposed conductive surface and may be configured to obtain physiological data while positioned within the body lumen. The sensor may be positioned within the housing such that the exposed conductive surface contacts the non-conductive material of the housing and is electrically isolated from the conductive material.

Abstract: An intraluminal sensing device may include an elongate member, a sensor, an acoustic matching layer, and a housing. The elongate member may be configured to be positioned within a body lumen of a patient. The sensor may be configured to obtain physiological data while positioned within the body lumen and may include a proximal surface and an opposite, distal surface. The acoustic matching layer may be disposed on the distal surface. The housing may be positioned at a distal portion of the elongate member and may terminate at a distal end. The housing may include a hollow interior with a planar surface, and the sensor may be positioned within the hollow interior such that the proximal surface of the sensor is disposed on the planar surface. A thickness of the acoustic matching layer may be defined by a distance between the distal surface and the distal end.

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.
