Abstract
The present disclosure relates to a method apparatus for transmyocardial revascularization. The apparatus includes an incision needle for creating an incision within a patient's heart to define a channel, and an electrocautery assembly operatively associated with the incision needle for transferring thermal energy to an inner surface of the channel to reduce bleeding therefrom and to prevent the channel from closing. Preferably, thermal energy is not transferred to the epicardium to create a flap or channel cap after the cylindrical incision needle is removed from relevant tissue to reduce bleeding from the channel.
