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