摘要: Improved methods and devices related to laser-assisted transmyocardial revascularization (TMR), more particularly, improved for creating branched TMR channels through myocardium in which a single opening is made an epicardial surface with plurality of channel branches, having predetermined geometries extending into myocardium, depending therefrom. A method comprises piercing mechanically or laser energy, directing energy the first angular orientation respect create delivering second branch. branches can thus be created structure. guide block device allows provides structure from opening. Rotating finger held rotating head means include hand elongated wand-like handle portion, portion hollow needle means. Preferred embodiments further comprise delivery advancing mechanism
