1. A remanufactured medical sensor, comprising:
- a padding layer;
a flexible circuit secured to the padding layer and comprising a plurality of conductors disposed on a flexible substrate;
an emitter electrically coupled to the flexible circuit and adapted to transmit light into a patient tissue;
a first detector coupled to the flexible circuit and configured to detect a first portion of light passing through the patient tissue;
a second detector coupled to the flexible circuit and configured to detect a second portion of light passing through the patient tissue; and
a patient-contacting adhesive layer configured to secure the remanufactured medical sensor to the patient tissue;
wherein the padding layer is a trimmed padding layer from a used medical sensor, and wherein the patient-contacting adhesive layer is a new patient-contacting adhesive layer that is disposed directly on a used patient-contacting adhesive layer of the used medical sensor, and wherein the used patient-contacting adhesive layer is trimmed such that a perimeter of the used patient-contacting adhesive layer fits within extents of the new patient-contacting adhesive layer.

Abstract
Remanufactured medical sensors and methods for remanufacturing used medical sensors are provided. Such a remanufactured sensor may include certain components from a used medical sensor and certain new components. For example, a remanufactured regional oximetry sensor may include a padding layer, an emitter and a pair of detectors, a flexible circuit coupled to the emitter and detectors, and a patient-contacting adhesive layer. The flexible circuit, the emitter, the first detector, the second detector, or any combination thereof, are from a used medical sensor, and the padding layer, the patient-contacting adhesive layer, or a combination thereof, are new.
