1. A sensing apparatus comprising:
- a cable having a first end, a second end and a core, wherein the core extends from the first end of the cable to the second end of the cable;
a connector residing at the first end of the cable; and
a sensor module residing at the second end of the cable; and
a conductive element extending from the connector to the sensor module, the conductive element being helically wrapped around at least a substantial length of the core;
wherein the sensor module comprises a first end and a second end; and
wherein beads encapsulate the first end and the second end.

Abstract
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.
