Document Type and Number:
Japanese Patent JP2018140180
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an improved sensor guide wire comprising an improved tip, with sufficient pull strength and which tip is flexible in all directions, and which also is improved regarding the capability of being steered through the various bends and turns in the vessels.SOLUTION: The present invention relates to a sensor guide wire for intravascular measurements of at least one variable in a living body, which sensor guide wire has a proximal region, a distal sensor region and a tip region. The sensor guide wire comprises, a sensor element arranged in the sensor region, a tip region core wire 5 having a longitudinal axis 6 and extending essentially along the tip region, and a coil 7 arranged in the tip region. The coil 7 at least partly encloses the tip region core wire 5. A distal tip joint 8 is arranged at a distal end 9 of the sensor guide wire for attaching the coil 7 to the tip region core wire 5. A major part of the tip region core wire 5 has a circular cross-section in a plane perpendicular to a longitudinal axis 6.SELECTED DRAWING: Figure 2b
