Claims28
A guidewire assembly, comprising:
- a substantially flexible flat member having been wound into coils to form a spring-like flexible tip member having a side and an end;
- a plurality of projections separated and bent away from the side of the flat member so that they extend in a direction different from the direction in which the coils are wound;
- and
- at least one electromagnetic microsensor attached to each of the plurality of projections, wherein the at least one electromagnetic microsensor comprises an electromagnetic microcoil with a ferrite core and wire wound around the ferrite core.
