Sensor guide wire with three-hole jacket for improved manufacturability and reduced drift

A guide wire for biological pressure measurement comprising:

• a tube extending along an axial direction of the guide wire, wherein the tube comprises a circumferential wall and defines a proximal-end opening and a distal-end opening;
• and
• a pressure sensor configured for biological pressure measurement, wherein at least a portion of the pressure sensor is mounted within the tube, and wherein the pressure sensor comprises a pressure sensor transducer,
• wherein the circumferential wall of the tube includes exactly three openings configured for fluid and gas ingress and egress extending radially therethrough:
• a first elongated opening located at a location opposing the pressure sensor transducer such that the pressure sensor transducer is exposed via the first elongated opening,
• a second elongated opening located such that, in a cross-sectional view, a bisector of the second elongated opening is offset from a bisector of the first elongated opening in a first circumferential direction by an angle in a range of 95 to 115 degrees, and
• a third elongated opening located such that, in the cross-sectional view, a bisector of the third elongated opening is offset from the bisector of the first elongated opening in a second circumferential direction by an angle in a range of 95 to 115 degrees,
• wherein each of the first, second, and third elongated openings is elongated in the axial direction of the guide wire,
• wherein a majority of each of the first, second, and third elongated openings is located within a distal half of the tube,
• wherein, in the cross-sectional view, a circumferential angle over which the first elongated opening extends is greater than a circumferential angle over which the second elongated opening extends and a circumferential angle over which the third elongated opening extends.
