1. A tissue oximeter device comprising:
- a probe comprising;
a cable interface, the cable interface being adapted to allow the probe to be coupled to a first radiation source, a second radiation source, and a first photodetector, wherein the first radiation source, second radiation source, and first photodetector are external to the probe; and
a sensor head comprising a first source structure and a first detector structure, the first source structure being arranged to be coupled to the first and second radiation sources via the cable interface, and the first detector structure being arranged to be coupled to the first photodetector via the cable interface; and
a console, external to the probe, comprising the first radiation source, second radiation source, first photodetector, and a beam combiner, external to the probe, coupling the first source structure to the first and second radiation sources via the cable interface.

Abstract
A probe for a medical device with source and detector sensors is used to monitor or measure, or both, oxygen saturation levels in a tissue. In various specific implementations, the probe has at least two sources and at least one detector, at least one source and at least two detectors, and at least two sources and at least four detectors. A source of the probe is connected to at least one radiation source, which is external to the probe. A detector of the probe is connected to a photodetector, which is external to the probe.
