Abstract: Processes for fabricating physiological characteristic sensor devices are disclosed here. An embodiment of the fabrication process forms a circuit pattern on a base substrate, where the circuit pattern includes circuit layouts for multiple die locations. Component stacks are mounted to the circuit layouts. Each stack has features and components to provide processing and wireless communication functionality for obtained sensor data.

Abstract: Hermetically sealed assemblies, for example, that include IC chips, are configured for incorporation within a connector terminal of an implantable medical electrical lead, preferably within a contact member of the terminal. An assembly may include two feedthrough subassemblies, welded to either end of the contact member, to form an hermetic capsule, in which an IC chip is enclosed, and a tubular member, which allows a lumen to extend therethrough, along a length of the terminal. A multi-electrode lead may include multiplexer circuitry, preferably a switch matrix element and a communications, control and power supply element that are electrically coupled to the contact member and to another contact member of the terminal. Each pair of switch matrix switches allows for any two of the electrodes to be selected, in order to deliver a stimulation vector, via stimulation pulses from a device/pulse generator, to which the connector terminal is connected.
