摘要：
An apparatus includes a proximal coil, a distal coil, a navigation sensor, and a wire. The proximal coil is formed by a wire wrapped in a helical configuration. The distal coil is formed by a wire wrapped in a helical configuration. At least one wrap at a proximal portion of the distal coil is interlocked with at least one wrap at a distal portion of the proximal coil, such that interlocking portions of the proximal and distal coils form a double helix configuration. The navigation sensor is located within the distal coil. The navigation sensor is configured to generate signals in response to movement within an electromagnetic field. The wire extends through the proximal coil. The wire is in electrical communication with the navigation sensor such that the wire is configured to communicate signals from the navigation sensor.
