    摘要： An apparatus for maintaining a robotic catheter system in a responsive state includes a catheter, a plurality of linear translatable control elements, and a controller. In an embodiment, the catheter includes a proximal portion, a distal portion, and at least two steering wires. The steering wires may be configured at one end to control the movement of at least a portion of the distal portion of the catheter and at the other end for connection to a control member. In an embodiment, each control element may be configured to engage or interface with a respective control member, and the controller may be configured to measure a force exerted on at least one control member by a respective control element and further configured to linearly translate the control element to substantially maintain a force within a predetermined range.

    摘要： Ablation electrode assemblies include an inner core member and an outer shell surrounding the inner core member. The inner core member and the outer shell define a space or separation region therebetween. The inner core member is constructed from a thermally insulative material having a reduced thermal conductivity. In an embodiment, the space is a sealed or evacuated region. In other embodiments, irrigation fluid flows within the space. The ablation electrode assembly further includes at least one thermal sensor in some embodiments. Methods for providing irrigation fluid during cardiac ablation of targeted tissue are disclosed that include calculating the energy delivered to irrigation fluid as it flows within the ablation electrode assembly through temperature measurement of the irrigation fluid. Pulsatile flow of irrigation fluid can be utilized in some embodiments of the disclosure.

    摘要： A method of manufacturing a catheter assembly generally includes providing a catheter shaft having an outer layer and an inner reinforcing layer; removing at least a portion of the outer layer from a length of the distal end of the catheter shaft in order to expose a distal segment thereof; providing an inner jacket segment; axially engaging the inner jacket segment with an interior surface of the distal segment of the catheter shaft; providing an outer jacket segment around at least the exposed exterior region of the distal segment of the catheter shaft; and bonding the distal segment of the catheter shaft to the inner jacket segment and the outer jacket segment.
