摘要： The distal end of the catheter can be constructed to include one or more features to provide strain relief to wiring of multiple single axis sensors. In some examples, the multiple single axis sensors and associated wiring can be manufactured over a flexible tube that can be placed over a movable support member. In some examples, wiring can be wound an increased number of consecutive traverse turns on a distal and/or proximal side of a single axis sensor, and a shrink sleeve may be positioned over the traverse turns. In some examples a wire shield transition point can be positioned on a straight portion in a proximal direction to the distal portion of the catheter.

摘要： A flexible circuit including a first segment including a base section of the flexible circuit; a second segment including a lateral wall section; a transition section between the base and lateral wall sections, the transition section being at least partially positioned adjacent a shared region of the base and lateral wall sections; and one or more electrode regions including a respective electrode, the one or more electrode regions being positioned at least partially in the transition section and the second segment.

摘要： A spring assembly usable with an intravascular catheter can include a tubular body, two mounting surfaces, and a compressible framework. The tubular body extends along a longitudinal axis and is sized to traverse vasculature. Each mounting surface can be configured to engage a substantially planar electrical circuit and is positioned in the tubular body each in a respective plane perpendicular to the longitudinal axis. The mounting surfaces face toward each other in opposite directions. The compressible framework extends between the first and second mounting surfaces. The spring assembly can further include a pair of electrical circuits mounted to the pair mounting surfaces. Each electrical circuit can include an inductive coil such that the pair of electrical circuits is a distance transducer. A change in distance between the pair of electrical circuits can be detected when the compressible framework is compressed and/or bent.
