    摘要: Embodiments of the present invention provide an irrigated catheter having irrigation fluid directed at target areas where coagulation is more likely to occur so as to minimize blood coagulation and the associated problems. In one embodiment, an irrigated ablation electrode assembly for use with an irrigated catheter device comprises a proximal member having at least one passageway for a fluid with an outlet disposed at an external surface of the proximal member; and a distal member connected with the proximal member and having an external surface. The distal member includes an electrode. The external surface of the proximal member and the external surface of the distal member meet at an intersection. The at least one passageway of the proximal member is configured to direct a fluid flow through the outlet toward a region adjacent the intersection.

    摘要: Irrigated ablation catheter assemblies and methods of facilitating parallel irrigation fluid flow along irrigated assemblies includes a catheter, an irrigated ablation electrode assembly, a flow member, and a catheter shaft having a fluid lumen. The electrode assembly includes at least one irrigation passageway and a distal portion. The proximal portion can include a proximal member and the distal portion can include a distal member which is connected to the proximal member. The proximal end of the flow member couples to the catheter shaft and the distal end of the flow member is disposed about the proximal portion of the assembly. Fluid flow is guided at least in part by the member and traverses the outer surface of the proximal portion along the outer surface of the distal portion substantially parallel with the longitudinal axis of the electrode assembly.

    摘要: Systems and methods are disclosed for assessing electrode-tissue contact for tissue ablation. An exemplary electrode contact sensing system comprises an electrode 10 housed within a distal portion of a catheter shaft 14. At least one electro-mechanical sensor 20 is operatively associated with the electrode 10 within the catheter shaft 14. The at least one electro-mechanical sensor 20 is responsive to movement of the electrode 10 by generating electrical signals corresponding to the amount of movement. The system may also include an output device electrically connected to the at least one electro-mechanical sensor 20. The output device receives the electrical signals for assessing a level of contact between the electrode 10 and a tissue 12.
