Technique for remanufacturing a BIS sensor
First Claim
1. A remanufactured bispectral index (BIS) sensor, comprising:
- a backing layer;
first, second, and third electrodes disposed on the backing layer and comprising a conductive ink, wherein the first, second, and third electrodes are adapted to be in electrical contact with a patient to perform BIS measurements;
a first foam layer disposed on at least a portion of the backing layer;
a second foam layer disposed on at least a portion of the first foam layer;
a first adhesive layer configured to secure the first foam layer to the second foam layer; and
a second adhesive layer attached to the second foam layer and configured to secure the remanufactured BIS sensor to the patient; and
wherein at least a portion of one of the first, second, and third electrodes and at least a portion of the backing layer are from a used medical sensor, and the second adhesive layer is new.

Abstract
Remanufactured BIS sensors and methods for remanufacturing used BIS sensors are provided. Such a remanufactured sensor may include certain components from a used medical sensor and certain new components. For example, a remanufactured BIS sensor may include a backing layer and at least first, second, and third electrodes disposed on the backing layer having a conductive ink. The first, second, and third electrodes are adapted to be in electrical contact with a patient to perform BIS measurements. A foam layer may be disposed on at least a portion of the backing layer, and an adhesive may be attached to the foam layer and is configured to secure the remanufactured BIS sensor to the patient. The first electrode, the second electrode, the third electrode, the backing layer, or a combination thereof, may be new and the foam layer, the adhesive, or a combination thereof, may be from a used medical sensor.

15. A remanufactured bispectral index (BIS) sensor, comprising:
-
a BIS sensor, comprising; a backing layer, wherein the backing layer is non-elastomeric; and first, second, and third electrodes disposed on the backing layer and comprising a conductive ink, wherein the first, second, and third electrodes are configured to be in electrical contact with a patient to perform BIS measurements; and a foam layer disposed on at least a portion of the backing layer; a new base layer disposed on the backing layer on a side that is opposite from a side on which the first, second, and third electrodes are disposed, wherein the new base layer is elastomeric; and an adhesive attached to the new base layer and configured to secure the remanufactured BIS sensor to the patient; wherein the backing layer has a periphery trimmed to fit within a periphery of the new base layer, wherein the backing layer comprises a first backing portion on which the first electrode is disposed, a second backing portion on which the second electrode is disposed, and a first bridge coupling the first and second backing portions, wherein the new base layer comprises a first base portion disposed on the first backing portion, and a second base portion disposed on the second backing portion, and a second bridge coupling the first and second base portions, wherein the second bridge is stretchable to enable a distance between the first and second electrodes to vary and the first bridge is folded to enable the distance between the first and second electrodes to vary, and wherein the second bridge comprises one or more notches to enable rotational movement of the first electrode with respect to the second electrode. - View Dependent Claims (16)
