摘要： A method of treating cardiac arrhythmia, including guiding a distal end portion of a catheter, the distal end portion having a distal tip and accommodating at least one ablation electrode into a desired intracardiac region, for example, from the inferior vena cava into the right atrium of a human heart, and then from the right atrium into the right ventricle of the heart, pulling the catheter backwards, for example, towards the inferior vena cava, until the distal tip engages an edge of an intracardiac orifice, for example, the tricuspid annulus whereby the at least one electrode engages a target tissue, for example, the isthmus of tissue between the tricospid annulus and the inferior vena cava, deflecting the distal tip into a hook-shaped configuration, and activating the at least one electrode to produce a substantially continuous lesion on the target tissue. The method makes use of a catheter pre shaped at its distal end, steerable with pull wires in two different normal planes, having one electrode which slides along the distal tip of the catheter.

摘要： An apparatus for mapping and/or ablating tissue includes a braided conductive member that may be inverted to provide a ring-shaped surface. When a distal tip of the braided conductive member is retracted within the braided conductive member, the lack of protrusion allows the ring-shaped surface to contact a tissue wall such as a cardiac wall. In an undeployed configuration, the braided conductive member is longitudinally extended, and in a deployed configuration, the distal end of the braided conductive member is retracted to invert the braided conductive member.

摘要： Methods and apparatuses for manipulating an elongated flexible shaft of a catheter provide ease and reliability of positioning electrodes against or near tissue. Dual-bend flexible distal tips (30) may be used in combination with flat wires. In some embodiments, flat wires which are free to rotate upon initial bending of shaft segments are employed. In some embodiments, one or more transition segments (48) are used to relocate the satellite lumen-to-main lumen transition of pull wires (42, 40) away from a change in shaft stiffness.
