Claim 0:
1. A medical system, comprising:
a probe for insertion into a blood vessel of a brain, the probe comprising:
a first optical fiber, which comprises a first optical diffuser at a distal end thereof and which is configured to guide an optical signal to a first location in and along the blood vessel and to diffuse the optical signal so as to interact with a brain clot in the blood vessel;
a second optical fiber, which comprises a second optical diffuser at a distal end thereof and longitudinally staggered relative to the first optical diffuser and which is configured to collect the diffused optical signal that interacted with the brain clot, at a second location in and along the blood vessel that is different from the first location;
a lumen extending along the probe and defining a working channel, the working channel configured to receive, and for removal of, the brain clot; and
a magnetic position sensor configured to detect a magnetic field output by a magnetic field radiator; and

an electro-optical measurement unit comprising an optical coupler and a light source, the electro-optical measurement unit configured to transmit the optical signal to the first optical fiber, and to receive and measure the diffused optical signal from the second optical fiber; and
a processor, configured to:
identify a composition of the brain clot by analyzing the measured diffused optical signal, wherein analyzing the measured diffused optical signal comprises distinguishing between an absorption-related component and a scattering-related component in the measured diffused optical signal;
determine a position and orientation of the probe based at least in part on signals received from the magnetic position sensor;
output to a connected display an image representative of the brain clot and a position and orientation of the probe;
output to the connected display the identified composition of the brain clot; and
output to the connected display a recommendation for selecting a brain clot removal technique using a method that matches the composition of the brain clot and includes removal of the brain clot via the working channel.
