A substrate with hermetically sealed vias extending from one side of the substrate to another and a method for fabricating same. The vias may be filled with a conductive material such as, for example, a fritless ink. The conductive path formed by the conductive material aids in sealing one side of the substrate from another. One side of the substrate may include a sensing element and another side of the substrate may include sensing electronics.

Sensor substrate and method of fabricating same

A system is provided for sensing blood glucose data of a patient. The system includes a sensor, user interface, and an optional auxiliary device. If the connection between the sensor and user interface is by a wire, the sensor remains powered when the wire is disconnected. The communication between the sensor and the user interface may be wireless. The auxiliary device can be a patient monitor or other display or signal device, which displays information about the blood glucose data collected by the sensor. The sensor is connected to sensor electronics, which include a sensor power supply, a voltage regulator, and optionally a memory and processor.

Sensing system with auxiliary display

A sensing apparatus with a connector, a sensor lead and a sensor module with a spacer placed over electrodes that have been deposited on a substrate. The spacer may have a space for receiving an enzyme. End portions of the sensor module may be encapsulated, such as with molded beads. A sensor lead may attach to the sensor module and may have an outer tubing that passes over the module and attaches to the beads at the end of the sensor module. The sensor lead may also attach to the connector such that the sensing apparatus may be electrically coupled to a pump, electronics or other devices. The sensing apparatus may be implanted into a vein or artery.

Sensing apparatus and process

An implantable coaxial lead includes a cable with male and female connectors. The cable includes inner and outer helical coils separated by an inner insulator tube, with an outer insulator tube surrounding the outer helical coil. The male connector includes an outer conductive cylinder, a conductive pin and an insulator molded in between. For increased strength, a braided cylinder, infused with rubber, is included at the juncture of the male connector and the cable. The female connector includes a cylinder formed by two conducting body elements and an intervening insulating body element. The female connector includes respective conductive tension elements configured to engage the male connector. A first seal is provided between the conductive tension members for electrical isolation and tactile feedback. An insertion tool includes a cylinder with a hollow bore and detachable head, and a rod for pulling the lead through the cylinder.

An in-line, multipolar proximal connector assembly for an implantable stimulation lead is provided which incorporates at least one sensor. Advantageously, the present invention uses straight conductive rods, or wires, to electrically connect the proximal terminals to a multilumen lead body. The straight conductive rods enable the diameter of the lead assembly to remain small. Additional terminals can easily be added by simply decreasing the spacing between terminals and adding additional conductive rods. In one embodiment, insulating spacers are premolded to include protruding portions which interlock with the ring terminals. Recesses within the insulating spacers are dimensioned to self-position the ring terminals a precise distance from the pin terminal according to precise dimensions defined by the VS-1 (or other) standards. In another embodiment, the terminals are injection molded. While the present invention is directed towards a quadrapolar (four conductors) design, it may be easily adapted to a bipolar, tripolar or multipolar (five conductors or more) design.
