Abstract: A roll-detecting sensor assembly includes a coil extending along and disposed about an axis. The coil comprises one or more portions, with each portion defining a winding angle. At least one of the portions defines a winding angle that is substantially nonzero relative to a line perpendicular to the axis, whereby the projected area of the coil in an applied magnetic field changes as the coil rotates about the axis. As a result, the coil is configured to produce a signal responsive to the magnetic field indicative of the roll of the sensor about the axis. In an embodiment, at least one of the portions defines a winding angle that is at least 2 degrees. In an embodiment, at least one of the portions defines a winding angle that is about 45 degrees.

Abstract: An elongate medical device having an axis comprises an inner liner, a jacket radially outward of the liner, a braid comprising metal embedded in the jacket, a sensor, and at least one wire electrically connected to said sensor. The at least one wire is one of: embedded in the jacket and optionally disposed helically around the braid; extending longitudinally within a tube which extends generally parallel to the device axis and wherein the tube is embedded in the jacket; and disposed within a lumen, wherein the lumen extends longitudinally within the jacket.

Abstract: An elongate medical device includes a sensor configured to detect one or more characteristics of an electromagnetic field in which the device is disposed. The sensor includes an electrically-insulative substrate, rectangular in shape, and a patterned, conductive trace disposed on the substrate. The patterned trace includes a plurality of diagonal sections parallel to one another, arranged with a relatively low pitch. The substrate is wrapped into a cylindrical shape thereby forming a three-dimensional spiral capable of functioning as a micro-electromagnetic sensor. A medical positioning system is responsive to the signal from the sensor to determine a position and/or orientation of the sensor.
