Spacer for sensor in intraluminal sensing device

A method for assembling an intraluminal device, the method comprising:

• obtaining a flexible elongate member configured to extend in a longitudinal direction within a body lumen of a patient;
• positioning a sensor housing at a distal region of the flexible elongate member;
• positioning a spacer within the sensor housing;
• and
• positioning a sensor at least partially within the sensor housing distal of the spacer, wherein the sensor is configured obtain intraluminal data associated with the body lumen, wherein the spacer comprises:
• a base;
• a through-hole extending through the base;
• a recess disposed above the base and surrounded at least partially by a side wall extending distally from the base, wherein the side wall is configured not to contact a proximal surface of the sensor;
• and
• a plurality of support ledges projecting radially inward from the side wall and configured to contact the proximal surface of the sensor.
