摘要：A myocardial revascularization device has a catheter suitable for use in amyocardial revascularization procedure, the catheter including an elongate body having aproximal end and a distal end, and tissue-ablating means housed at least partially within
the catheter and capable of effectuating tissue ablation adjacent the distal end of thecatheter. The device further has an optical reflectance fiber housed within the catheterand coupled to an optical reflectance system. The device is operative to transmit areflectance signal in the optical reflectance fiber, the reflectance signal including eithershort optical pulses or low-coherence light. The optical reflectance system is operativeto gauge tissue ablation, measure a thickness of tissue adjacent the catheter, and/ordetermine a position of the distal end relative to adjacent tissue using either of opticaltime-domain reflectance or optical coherence interferometry.
