March 24 /PRNewswire/ -- Circulase has announced that it is about to begin animal studies with a second-generation short pulse carbon-dioxide laser to scientifically establish the optimum treatment parameters for Transmyocardial Revascularization (TMR).
Circulase uses a proprietary carbon-dioxide laser design to generate extremely short pulses of high energy which drill TMR channels through the heart in less than 1 millisecond resulting in considerably less thermal damage to adjacent heart tissue.
Other notable Bell Labs laser achievements include the invention of the first continuously operating laser, in 1960; first continuously operating solid-state laser, 1961; first high-power carbon-dioxide laser
, 1964; first semiconductor laser that operates at room temperature (which set the basic principle for all semiconductor lasers used today), 1971; first single-frequency laser (used in the long-distance network and, more recently, in CATV systems), 1971; the first laser capable of generating solitons (ultra-short pulses that maintain their shape over long distances), 1983.
Writing for general and specialty veterinary practitioners, they discuss such topics as types of laser-tissue interaction related to the rate of heat transfer through soft tissue, pain management, and clinical applications of carbon-dioxide lasers
