Patent ID: 8333762

Claim:
An irrigated tip catheter comprising: a catheter body; a control handle proximal to the catheter body; a deflectable section distal of the catheter body; a tip electrode distal of the deflectable section, the tip electrode having an outer surface; a generally tubular member positioned at least partially over the tip electrode to direct fluid to flow over at least a portion of the outer surface, wherein the tubular member is mounted over at least a portion of a proximal end of the tip electrode and a distal end of the deflectable section, the tubular member having an inner surface spaced apart from the outer surface of the tip electrode to provide at least one fluid channel for the fluid to flow over the outer surface of the tip electrode; a cavity defined by the proximal end of the tip electrode, the distal end of the deflectable section, and the inner surface of the tubular member, wherein fluid entering the cavity is directed to the outer surface of the tip electrode; and at least one connective tube extending through the cavity to isolate components extending between the tip electrode and the deflectable section from exposure to the fluid.
