Sensor guide wire with micro-cable winding

摘要

A sensor guide wire for an intravascular measurement of a physiological variable in a living body includes a sensor region in a distal part of the sensor guide wire, a sensor element arranged in the sensor region, a male connector at a proximal part of the sensor guide wire, a least one electrical micro-cable connecting the male connector to the sensor element, and an elongated guide wire body arranged between the sensor region and the male connector. The at least one electrical micro-cable extends essentially helically around the guide wire body along the length of at least a part of the guide wire.

1. A sensor guide wire for an intravascular measurement of a physiological variable in a living body, comprising:
a sensor region in a distal part of the sensor guide wire, a sensor element arranged in said sensor region, a male connector at a proximal part of said sensor guide wire, at least one electrical micro-cable electrically connecting said male connector to said sensor element, and an elongated core wire or tube arranged between said sensor region and said male connector, wherein at least one helical groove is formed in an outer surface of the elongated core wire or tube so as to extend helically along at least a part of the elongated core wire or tube, wherein said at least one electrical micro-cable extends helically around said elongated core wire or tube along a length of at least part of the sensor guide wire, and wherein at least a part of said at least one electrical micro-cable is disposed in the helical groove of the elongated core wire or tube.
