Abstract:
A catheter probe comprising:a catheter shaft having a shaft tip section, a shaft distal end, a shaft proximal end, and at least one lumen extending between the shaft distal end and the shaft proximal end, wherein the shaft distal end has a shaft opening that is connected to and in communication with the at least one lumen;a handle attached to the shaft proximal end, wherein the handle has a cavity;a fluid supply source;fluid irrigation means for providing fluid to the shaft distal end, wherein the fluid irrigation means is externally connected to the fluid supply source; andfluid control means for controlling flow rate of the fluid irrigation means through the shaft opening at the shaft distal end, wherein the fluid control means comprises a fluid deployment mechanism at the handle and a movable cap that is distal to the shaft distal end, wherein the fluid deployment mechanism causes the movable cap to move toward the shaft distal end and positions said movable cap into said shaft opening to shut off flow of the fluid irrigation means at a non-deployed state, and wherein the movable cap is deployed by the fluid deployment mechanism to move distally away from the shaft opening of the shaft distal end to allow fluid flow out of the shaft opening.
