Abstract
Electrophysiological methods and apparatus are disclosed. An exemplary myocardial treatment method includes the steps of positioning an electrode on the epicardial surface of a ventricle and transmitting energy from the electrode, through the epicardial surface and into the ventricular wall to create a lesion within the ventricular wall. An exemplary apparatus includes a shaft and one or more electrodes that have a main portion and a needle portion.
Claims11
A myocardial revascularization and denervation method, comprising the steps of:
- positioning an electrode, including an electrode main portion and an electrode needle portion, on the epicardial surface such that the electrode main portion is on the epicardial surface of a ventricle;
- piercing the epicardial surface with the electrode needle portion such that the electrode needle portion is located within the ventricular wall;
- and
- transmitting energy from the electrode, through the epicardial surface and into the ventricular wall to create a lesion within the ventricular wall.
A myocardial revascularization and denervation method, comprising the steps of:
- positioning an electrode on the epicardial surface of a ventricle shaped such that the lesion produced thereby will define a first region relatively close to the epicardial surface with a relatively large cross-sectional area and a second region relatively far from the epicardial surface with a relatively small cross-sectional area;
- and
- transmitting energy from the electrode, through the epicardial surface and into the ventricular wall to create a lesion within the ventricular wall.
A myocardial revascularization and denervation method for use on a wall of the heart defining an epicardial surface and an endocardial surface, the method comprising the steps of:
- positioning a first lesion creation device on the epicardial surface;
- positioning a second lesion creation device within the heart wall;
- and
- forming a lesion with the first and second lesion creation devices.
