Catheters, Cardiac, Laser Percutaneous Myocardial Revascularization
Definition : Cardiac catheters designed for fiberoptic delivery of laser energy to the myocardium using percutaneous procedures, producing temporary myocardial channels. These devices typically consist of single-use, 6 Fr diameter, 125 cm (49 inch) length fiberoptic catheters with a 9 Fr sheath. Laser energy may induce real mechanisms of revascularization (e.g., myocardial angiogenesis), other mechanisms (e.g., myocardial denervation, myocardial fibrosis), and/or placebo effects. Percutaneous revascularization catheters are intended for palliative treatment of stable angina; they may also improve blood perfusion to the myocardium.
