Clinical experience with an excimer laser angioplasty system

摘要

Abstract: We report on a medical excimer laser system developed for laser angioplasty. One of the unique features of this excimer laser is the required low frequency of gas replenishment. Data presented, showing the time between gas changes, is approaching six months. As of December 1, 1990, more than 500 percutaneous coronary cases have been performed using this system. The catheters used for the majority of the cases are composed of 100 micron fiber bundles. The cutting depth per pulse is shown to be proportional to the catheter active area.!
