## Abstract

A sensor guide wire for intravascular measurement of a physiological variable includes: a core wire extending at least partly along a length of the sensor guide wire; a sensor element in a sensor region of the sensor guide wire; a jacket having a jacket wall, the jacket being fixed relative to the core wire; and at least one lead connected to the sensor element. The jacket is tubular and includes a proximal end opening, a distal end opening, and a first set of openings extending through the jacket wall. The first set of openings extending through the jacket wall includes a first opening located above the sensor element, a second opening located at a first lateral side of the sensor element, and a third opening located at a second lateral side of the sensor element, and wherein the first, second, and third openings are elongated in a longitudinal direction of the jacket, and are aligned in a circumferential direction of the jacket.

## Claims

### Claim 1

A sensor guide wire for intravascular measurement of a physiological variable, comprising:
a core wire extending at least partly along a length of the sensor guide wire;
a sensor element in a sensor region of the sensor guide wire;
a jacket having a jacket wall, the jacket being fixed relative to the core wire; and
at least one lead connected to the sensor element;
wherein the jacket is tubular and includes a proximal end opening, a distal end opening, and a first set of openings extending through the jacket wall, and
wherein the first set of openings extending through the jacket wall includes a first opening located above the sensor element, a second opening located at a first lateral side of the sensor element, and a third opening located at a second lateral side of the sensor element, and wherein the first, second, and third openings are elongated in a longitudinal direction of the jacket, and are aligned in a circumferential direction of the jacket.

### Claim 2 (depends on 1)

The sensor guide wire according to claim 1, wherein the jacket further includes a second set of openings extending through the jacket wall, the second set of openings including a fourth opening that is aligned with the first opening in a longitudinal direction of the jacket, a fifth opening that is aligned with the second opening in the longitudinal direction of the jacket, and a sixth opening that is aligned with the third opening in the longitudinal direction of the jacket, wherein the fourth, fifth, and sixth openings are elongated in the longitudinal direction of the jacket.

### Claim 3 (depends on 2)

The sensor guide wire according to claim 2, wherein the jacket further includes a seventh opening.

### Claim 4 (depends on 2)

The sensor guide wire according to claim 2, wherein the first set of openings is located at a distal portion of the jacket, and the second set of openings is located at a proximal portion of the jacket.

### Claim 5 (depends on 1)

The sensor guide wire according to claim 1, wherein the jacket wall extends essentially parallel to a longitudinal axis of the sensor guide wire.

### Claim 6 (depends on 1)

The sensor guide wire according to claim 1, wherein the first set of openings includes exactly three openings that are aligned in the circumferential direction of the jacket: the first opening, the second opening, and the third opening.

### Claim 7 (depends on 1)

The sensor guide wire according to claim 1, wherein the first set of openings is located at a distal portion of the jacket.
