Intravascular laser irradiation of blood (ILIB) used to treat lung diseases: a short critical review.

Intravascular laser irradiation of blood (ILIB) was developed to treat cardiovascular diseases due to its rheological effects. In its original form, ILIB was applied by an intravenous optical fiber, restricting its application. However, this technique was modified to non-invasive irradiation through the radial artery, now called vascular photobiomodulation (VPBM).
