Abstract: An intraluminal device is provided, which includes a flexible elongate member configured to extend in a longitudinal direction within a body lumen of a patient, with a sensor disposed at a distal region of the flexible elongate member and facing in the longitudinal direction. The sensor is configured obtain intraluminal data associated with the body lumen. The intraluminal device includes a housing at least partially surrounding the sensor. The housing includes a distal portion including a first conductive material and a first dielectric material. The distal portion is fixedly attached to a different proximal portion which includes a second conductive material and a second dielectric material. The first conductive material and the second conductive material are in electrical communication with the sensor.

Abstract: An intravascular guidewire can be positioned within a blood vessel and includes a proximal portion and a distal portion, a core wire, a polymer jacket positioned around the core wire, a sensor housing positioned at the distal portion, and a sensor positioned within the rigid sensor housing that obtains medical data associated with the blood vessel. The polymer jacket can include a first section with a first hardness and a second section with a second hardness. The first section can be disposed directly adjacent to the sensor housing, and the first section can have a greater durometer than the second section. The first and second sections can be first and second compositions of at least two polymers. The polymer jacket can include a third section that is a transition between the first composition and the second composition.
