Promotion of angiogenesis. A cross section of myocardium during channel creation with a TMR laser is shown and the interface between the inner (a) and outer (b) surface of the heart is depicted. The path of channel formation with the laser is depicted in c, with steam bubbles arising on the blood side due to heat generation during lasing. Clot formation and angiogenesis are shown at the site of the channel (d) and e as angiogenesis continues to be stimulated over time
