First Claim
Patent Images
1. An irrigation probe comprising:
- a generally rigid probe body having proximal and distal ends;
an electrode comprising an elongated electrode body having first and second ends, wherein the electrode defines an inner cavity, the electrode having at least one irrigation opening through which fluid can pass from the inner cavity to the outside of the electrode, the electrode being fixedly attached to the distal end of the probe body at a point along the elongated body of the electrode between the first and second ends wherein the distal end of the probe body and the electrode form an angle α
greater than 0°
; and
means for introducing fluid into the inner cavity.

Abstract
An irrigation probe useful for ablation during open heart surgery is provided. The irrigation probe comprises a generally rigid probe body and a handle mounted to the proximal end of the probe body. The generally rigid probe body has an electrode at its distal end having at least one irrigation opening through which fluid can pass. An infusion tube extends through the probe body for introducing fluid to the electrode.
