Abstract
A method of producing a miniaturized set of inductive coils set mutually orthogonally inside a tube. In the method a positional template made of a sheet of substantially rigid material that defines a set of guide apertures, each of which is in the shape of one of the set of inductive coils. The guide apertures are disposed so that when an inductive coil is fitted into each one of the guide apertures the coils will be substantially orthogonal to one another.

A method of producing a miniaturized set of inductive coils set mutually inside a tube, comprising:
- (a) providing a set of inductive coils;
- (b) providing a positional template, including a sheet of substantially rigid material, said sheet defining a set of guide apertures, each guide aperture of the set of guide apertures being in a cross-sectional shape of a respective inductive coil of said set of inductive coils;
- and
- (c) placing said set of inductive coils into said set of guide apertures, wherein the set of guide apertures cause the set of inductive coils to be substantially orthogonal to one another when the set of inductive coils are placed within the set of guide apertures.
A method of producing a miniaturized positional sensor for identifying a position within a patient, the method comprising:
- providing a flex circuit including a plurality of electrical traces;
- coupling a set of inductive coils to the plurality of electrical traces, wherein each inductive coil of the set of inductive coils has a three-dimensional shape that is substantially cylindrical;
- and
- positioning the set of inductive coils within a positional template, wherein (i) the positional template includes a plurality of guide apertures with each guide aperture of the plurality of guide apertures having a cross-sectional shape of a respective inductive coil of the set of inductive coils and (ii) the set of guide apertures cause the set of inductive coils to be substantially orthogonal to one another when the set of inductive coils are placed within the positional template.
The method of claim of 6 further comprising:
- providing epoxy material to affix the set of inductive coils to the flex circuit.
