Selective treatment of endocardial/myocardial boundary
First Claim
1. An apparatus for selective treatment of body tissue comprising:
- a guide tube defining a longitudinal axis and having proximal and distal ends and a first lumen;
a treatment device having proximal and distal ends slidably mounted within the first lumen and egressible from the-distal end of the guide tube; and
a deflection and depth stop member disposed at the distal end of the guide tube;
whereby the deflection and depth stop member determines both depth of the entry of the treatment device into tissue and an angle of the treatment device relative to the longitudinal axis.

Abstract
A method for treating myocardium using at least one mechanical or electromagnetic energy functional device for forming a network of branched, interconnecting passages in a boundary between endocardium and myocardium, thereby enhancing blood flow into the treated zone, and a device for selectively treating ischemic myocardium tissue comprising a tube having proximal end and distal end, and at least one hollow lumen and defining an axis, at least two mechanical or electromagnetic energy functional devices disposed within the tube, the at least two mechanical or electromagnetic energy functional devices each having a distal end disposed adjacent the distal end of the central tube, and a deflecting member adjacent the distal portion of the central tube for deflecting the distal end of each of the at least two mechanical or electromagnetic energy functional devices away from the axis, for enabling treatment of selective areas of ischemic or hibernating myocardium tissue.
