| 摘要 |
The present invention relates to a sensor guide wire (1) for intravascular measurements of at least one variable in a living body, which sensor guide wire (1) has a proximal region (2), a distal sensor region (3) and a tip region (4). The sensor guide wire (1) comprises, a sensor element arranged in said sensor region (3), a tip region core wire (5) having a longitudinal axis (6) and extending essentially along said tip region (4), and a coil (7) arranged in said tip region (4). The coil (7) at least partly encloses said tip region core wire (5), and a distal tip joint (8) is arranged at a distal end (9) of said sensor guide wire (1) for attaching said coil (7) to said tip region core wire (5). A major part of said tip region core wire (5) has a circular cross-section in a plane perpendicular to said longitudinal axis (6).
