Miniature implantable laser Doppler probe monitoring of free tissue transfer.


A 2.5-mm fiber-optic laser Doppler flowmetry probe has been applied in an experimental dog model as well as in 5 clinical cases to provide continuous readout of deep tissue perfusion. The rectus abdominis muscle in the dog was used for the experimental verification of the probe, which has a linear correlation with flow rate and a rapid response (6 seconds… (More)
