摘要：
1. A catheter apparatus comprising: an elongated shaft extending along an axis, including a proximal end portion and a distal end portion, where the distal end portion includes a first bending zone and a second bending zone located nearby and extending distally beyond the first bending zone； assembly coupled to the proximal end portion； thermocouple carried by the second bending zone and extending distally behind it； bending control element coupled to the first bending zone and configured and for applying a first force to the first bending zone to advance the first bending zone of the distal portion of the elongated rod radially from the axis； a flexible structure inside the second bending zone coupled to the thermocouple and configured to provide passive bending around the axis in response to the second force, attached to the thermocouple by contact with the surface of the fabric； a bending regulator carried by the handle assembly and coupled to the bending control element, configured to provide Appendicies first efforts to promote the first bending zone； and a connector carried by the handle assembly and configured to connect the thermocouple to a source of thermal energy； where the thermocouple is configured to apply heat to a tissue site near the surface of the fabric. 2. The catheter apparatus of claim 1, wherein the first bending zone is configured to advance in a predetermined radial direction in response to a first force exerted by the bending control. Catheter1. Катетерный аппарат, содержащий:удлиненный стержень, проходящий по оси, включающий проксимальный концевой участок и дистальный концевой участок, где дистальный концевой участок включает первую зону изгиба и вторую зону изгиба, расположенную поблизости и проходящую в дистальном направлении за первой зоной изгиба；рукоятку в сборе, сцепленную с проксимальным концевым участком；термоэлемент, переносимый второй зоной изгиба и проходящий дистально за ней；элемент контроля изгиба, сцепленный с первой зоной из
