Interconnect ring for microminiature electrical coil

Abstract:

An interconnect ring is used in attaching the leadwires to the coil wire ends of a microminiature sensor. The interconnect ring is affixed directly to an outside surface of either the core or the coil wire of the microminiature sensor. At least the two flexible ends of the coil wire are electrically joined to metal pads on the interconnect ring. Thereafter, the microminiature sensor can be handled with minimal risk of breakage, shorting or dislodging of the ends of the coil wire. Two other metal pads on the interconnect ring are left open for subsequent attachment of leadwires which can run the length of the catheter device in which the microminiature sensor is used.
