Abstract
A catheter has single axis sensors mounted directly along a portion of the catheter whose position/location is of interest. The magnetic based, single axis sensors are on a linear or nonlinear single axis sensor (SAS) assembly. The catheter includes a catheter body and a distal 2D or 3D configuration provided by a support member on which at least one, if not at least three single axis sensors, are mounted serially along a length of the support member. The magnetic-based sensor assembly may include at least one coil member wrapped on the support member, wherein the coil member is connected via a joint region to a respective cable member adapted to transmit a signal providing location information from the coil member to a mapping and localization system. The joint region provides strain relief adaptations to the at least one coil member and the respective cable member from detaching.
