Abstract: An actuator device with an actuator cup having a first end and a second end. The actuator cup defines a storage chamber containing a pyrotechnic material to produce gas. The storage chamber also includes a coolant. At least one electrical connection coupled to the first end, the electrical connection in reaction initiating communication with the pyrotechnic material. The second end of the actuator cup includes a concave surface before actuation of the pyrotechnic material and during the actuation of the pyrotechnic material the second end transitions from the concave surface to a convex surface.

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.
