Abstract

To overcome the abrupt closure and late restenosis after percutaneous transluminal coronary angioplasty (PTCA), new technology termed 'hot balloon angioplasty' has been considered. A novel laser-heated hot balloon catheter has been developed to address these problems. Its feasibility and acute thermal effects in the porcine coronary arteries in vitro was studied. As the balloon material was teflon (heat-resistant up to 240 degree(s)C). The temperature of the balloon could rise abruptly. So, intima~media were welded while marked thermal injury was not detected in adventitial tissue.
