Transmyocardial revascularization solid-state laser system
Definition
A mains electricity (AC-powered) device assembly in which input energy (e.g., flashlamp, diode laser) is used to excite a glass/crystal rod [typically yttrium-aluminium-garnet doped with holmium (Ho:YAG)] to emit a high-power laser beam intended for transmyocardial revascularization surgical procedures (open surgical approach); it does not include frequency-doubling technology. It includes a light source, controls/foot-switch and may include the handpiece/guide. It emits a midinfrared wavelength, and may be used with a handpiece capable of injecting agents/materials into the heart (e.g., stem cells).
