CATHETER WITH SINGLE AXIAL SENSORS
First Claim
1. A catheter comprising:
- an elongated body;
a distal member distal the elongated body, the distal member having a support member and a configuration;
a control handle proximal the elongated body;
a magnetic-based sensor assembly including at least one coil member that is 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, and the joint region provides strain relief to the at least one coil member and the respective cable member from detaching.

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.

21. A catheter comprising:
-
an elongated body; a distal member distal the elongated body, the distal member having a configuration; a control handle proximal the elongated body; a sensor assembly having a support member extending through the distal member and at least a proximal and a distal magnetic-based sensors, each sensor including a coil member that is wrapped on the support member, each coil member being connected via a respective joint region to a respective cable member adapted to transmit a respective signal providing respective location information from the respective coil member to a mapping and localization system, and each joint region including strain relief adaptation, wherein the proximal magnetic-based sensor includes a nonconductive tubing between the coil member and the support member, and the cable of the distal sensor extends between the nonconductive tubing and the support member.
