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