1. A method for providing revascularization treatment to a heart, said method comprising:
- placing a probe at a plurality of locations of said heart;
sensing a physiological characteristic of said heart at said locations;
creating a viability map of said heart based on said sensed physiological characteristic of said locations, said viability map indicating viable tissue of said heart;
creating at least one channel in said viable tissue of said heart according to said viability map; and
marking said map at a position according to where said at least one channel was created.

Abstract
An elongate probe for providing irradiation treatment of the heart, the probe having a distal end for engaging heart tissue of a subject, including a waveguide, which conveys radiation to the heart tissue; and a sensor, adjacent the distal end of the probe, which generates signals for use in controlling the treatment.

10. A system for providing revascularization treatment to a heart of a patient, said system comprising:
-
a console located exterior of said patient;
a probe operatively connected to said console, said probe having a position sensor, an electrode for sensing a physiological characteristic of said heart, and a waveguide for creating at least one channel in said heart, said probe creating a viability map of said heart for indicating viable tissue of said heart; and
wherein said console determines a position of said probe and a location for creating said at least one channel in said viable tissue of said heart according to said viability map, said console also controlling revascularization treatment to said heart through said waveguide. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A method for providing revascularization treatment to a heart, said method comprising:
-
placing a probe at a plurality of locations of said heart;
sensing a physiological characteristic of said heart at said locations wherein said physiological characteristic includes a movement of said heart locations;
creating a viability map of said heart based on said sensed physiological characteristic of said locations, said viability map indicating viable tissue of said heart; and
creating at least one channel in said viable tissue of said heart according to said viability map. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28)
