Claim 0:
1. A bipolar electrical device, comprising:
an outer shaft defining a lumen extending along a central axis, a proximal end and a distal end opposite the proximal end, in which the distal end forms a cutting window open to the lumen;
an inner shaft rotatably disposed within the lumen of the outer shaft about the central axis, the inner shaft defining a distal portion forming a cutting tip, the cutting tip and the cutting window together defining a cutting implement;
first and second electrically isolated electrode surfaces formed at the cutting implement and defining a space between each other; and
an irrigation channel within the space, the irrigation channel extending along the outer shaft and terminating in at least one outlet port proximally spaced from the cutting window and radially spaced relative to the outer shaft.
