    摘要： A catheter with a fluorescent temperature sensor is shown and described. The catheter includes a lumen, a fiber-optic cable that extends through the lumen. A distal end of the fiber-optic cable is coated with a fluorescent material and a proximal end of the fiber-optic cable is connected to a console. The console includes a light source for transmitting light through the fiber-optic cable for exciting the fluorescent material. The console further includes a photo multiplier tube for converting light emitted by the excited fluorescent material to a plurality of analogue voltage signals. The console further includes a digital oscilloscope linked to the photo multiplier tube for converting the plurality of analogue voltage signals to at least one digital signal. The console further includes a processor linked to the digital oscilloscope for converting the at least one digital signal to a temperature value for the distal end of the fiber-optic cable.

    摘要： The present invention relates to devices and methods for measuring the pH of blood in the vicinity of a vulnerable plaque. A balloon including an opto-electric device may be positioned proximate a vulnerable plaque. The balloon can be inflated to partially occlude blood flow enabling interaction between lipid laden blood and pH-sensitive material either within the balloon or on the wall(s) of the balloon. The selected pH-sensitive material is one whose optical properties change as a function of the pH of blood in the vasculature. An opto-electric device may be used for measuring the optical property and/or the change in the optical characteristics of the pH-sensitive compound.
