1. A device for measurement of an analyte concentration in a host, the device comprising:

  • a sensor comprising a first electrode and a second electrode coaxially located with the first electrode, wherein the sensor comprises an in vivo portion configured for insertion into a host and an ex vivo portion configured for electrical connection to sensor electronics located outside of the host, wherein the ex vivo portion comprises a first electrical connection area associated with the first electrode and a second electrical connection area associated with the second electrode;

    a membrane system disposed on an electroactive portion of the first electrode; and

    a contact subassembly configured to electrically connect the sensor with sensor electronics, wherein a first electrically conductive portion of the contact subassembly circumscribes at least a portion of a periphery of the first electrical connection area, and wherein a second electrically conductive portion of the contact subassembly circumscribes at least a portion of a periphery of the second electrical connection area.
