Abstract

The temperature response of a 2. 0-mm-diameter metal laser probe, or hot tip, to 10-W Nd:YAG laser power input was measured in various stationary media. In blood the probe temperature reached 600 degree C in 3 s. The temperature rise resembled the rise in air more than in saline, where the probe temperature remained at 100 degree C due to boiling heat loss. The fast temperature rise in blood is attributed to the formation, at 70-100 degree C probe temperature, of a thin envelope of denatured blood which entraps an insulating layer of vapor of 0. 3-0. 5-mm thickness. It is concluded that hot tip recanalization is greatly influenced by the medium, blood or saline, that is present in the artery.
