Sensor systems having multiple probes and electrode arrays

摘要

Embodiments of the invention provide amperometric analyte sensors having multiple related structural elements (e.g. sensor arrays comprising a working, counter and reference electrode) and algorithms designed for use with such sensors. While embodiments of the innovation can be used in a variety of contexts, typical embodiments of the invention include glucose sensors used in the management of diabetes.

主权项

1. An amperometric analyte sensor system comprising:
a probe platform; a first probe coupled to the probe platform and adapted to be inserted in vivo, wherein the first probe comprises:
a first electrode array comprising a working electrode, a counter electrode and a reference electrode; anda second electrode array comprising a working electrode, a counter electrode and a reference electrode; a second probe coupled to the probe platform and adapted to be inserted in vivo, wherein the second probe comprises:
a third electrode array comprising a working electrode, a counter electrode and a reference electrode; anda fourth electrode array comprising a working electrode, a counter electrode and a reference electrode;wherein the first, second, third and fourth electrode arrays are configured to be electronically independent of one another; and
the system further comprises:
a processor;a computer-readable program code having instructions, which when executed cause the processor to: assess signal data obtained from each of the first, second, third and fourth electrode arrays against one or more reliability parameters; rank signal data from each of the first, second, third and fourth electrode arrays in accordance with the assessment against the one or more reliability parameters; and compute an analyte concentration based upon the ranking of signal data obtained from each of the first, second, third and fourth electrode arrays.
