摘要： Electrode assemblies include segmented electrodes disposed on a catheter. The segmented electrodes can be constructed at the tip of the catheter or more proximally located. Tip electrodes can be constructed from an electrically-insulative substrate covered with a conductive material. The conductive material can be deposited on the electrically-insulative substrate to form a single tip electrode or multiple segmented electrodes. In some embodiments the tip electrode can include irrigation flow holes for irrigation. A method of manufacturing a tip electrode comprising a thin layer of conductive material deposited on an electrically-insulative substrate is disclosed. Segmented ring electrodes can be constructed from segmented ring electrodes that can be equally separated around a circumference of a catheter. The segmented ring electrodes can be formed into segmented electrode subassemblies that can then be joined to a catheter shaft.

摘要： Method and devices for delivering pulsed RF ablation energy to enable the creation of lesions in tissue are disclosed. The delivery of RF energy is controlled such that the generator power setting remains sufficiently high to form adequate lesions while mitigating against overheating of tissue. An ablation catheter tip having high-thermal-sensitivity comprises a thermally-insulative ablation tip insert supporting at least one temperature sensor and encapsulated, or essentially encapsulated, by a conductive shell. A system for delivering pulsed RF energy to a catheter during catheter ablation comprises an RF generator and a pulse control box operatively connected to the generator and configured to control delivery of pulsatile RF energy to an ablation catheter comprising at least one temperature sensor mounted in its tip. Also disclose is a method of controlling the temperature of an ablation catheter tip while creating a desired lesion using pulsatile delivery of RF energy.

摘要： In various embodiments, a catheter comprising an expandable electrode assembly or basket is provided. In specific embodiments, the basket is particularly useful for mapping electrical activity at one or more locations within the heart. The basket can comprise a plurality of bendable or deflectable arms. At least one of the arms may have varied flexibility over its length in the form of one or more discontinuities of stiffness or flexibility at an elbow region or other variances in flexibility over the arm's length. Such variance in flexibility may allow the arm to assume a different bent configuration or respond to external factors more positively than possible with an arm having a static or near static flexibility or stiffness over its length.
