    Abstract: A system for diagnosis or treatment of tissue in a body is provided. The system includes an ablation catheter having a deformable, elongate shaft having proximal and distal ends. The catheter further includes an ablation delivery member disposed proximate the distal end of the shaft and configured to deliver ablation energy to ablate the tissue. In one embodiment, the ablation delivery member comprises an ablation electrode and may also be configured to generate a signal indicative of electrical activity in the tissue. The catheter further includes one or more sensing electrodes disposed proximate the ablation delivery member. The sensing electrodes are configured to generate signals indicative of electrical activity in the tissue. The system further includes an electronic control unit configured to control delivery of ablation energy from the ablation delivery member responsive to one or more of the generated signals indicative of electrical activity in the tissue.

    Abstract: An irrigated ablation electrode assembly comprises a distal member, a first manifold, and a second manifold. The distal member includes an outer surface; an inner surface; and at least one radially extending passageway that extends from the inner surface of the distal member to the outer surface of the distal member. The first manifold includes an outer surface, an inner cavity, and at least one radially extending passageway that extends from the inner cavity to the outer surface of the first manifold. The second manifold includes an outer surface, an inner surface, and at least one radially extending passageway that extends from the inner surface of the second manifold to the outer surface of the second manifold. Other irrigated ablation electrode assemblies are also presented.

    Abstract: An ablation electrode assembly is provided with improved irrigation cooling of the assembly and ablation site. The assembly includes a proximal end configured to be coupled to a catheter shaft and a distal end configured to deliver ablation energy to tissue. The assembly further includes a fluid manifold extending from the proximal end to the distal end and configured to fluidly communicate with a fluid lumen in the catheter shaft. The fluid manifold defines an axial passageway centered about a longitudinal axis extending in the longitudinal direction of the assembly. The axial passageway has a distal end terminating prior to the distal end of the electrode assembly. The assembly further includes means for creating turbulence in fluid exiting the first axial passageway.
