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.

A compressible, flexible shape-retaining sleeve fits around a hearing aid shell. The sleeve includes fins having a fold line which extend outward to contact the user's ear canal, changing the hearing aid from being largely non-occlusive to being substantially occlusive. The hearing aid, including its shell, can be repeatedly inserted and removed from the sleeve through the battery door opening. The sleeve also has openings for a flexible filament positioning structure, consistently positioning the hearing aid for both occlusive and non-occlusive use. While the flexible filament positioning structure is attached to the hearing aid, it prevents disengagement of the sleeve from the hearing aid shell during insertion and removal of the hearing aid from the user's ear canal.
