Abstract
Distal catheter assemblies, catheters, and methods for minimizing damage to heat and/or magnetically sensitive components are provided. A distal catheter assembly comprises a distal housing having a cavity and a separate proximal mounting member. A first component, e.g., a sensor, is mounted within the cavity of the housing, and a second component, e.g., a steering assembly or RF wire, is mounted to the proximal mounting member. If the proximal mounting member is hollow, it may have a window to provide access to the inner surface of the proximal mounting member to facilitate mounting of the second component. After the first and second components are mounted, the proximal mounting member can then be affixed to the distal housing, thereby minimizing any adverse affects on the sensitive component that may otherwise result from mounting the first and second components on a single member. In the preferred embodiment, the distal housing includes a cap-shaped head, and the proximal mounting member includes a cylindrical neck section, with the head forming an ablation electrode. In this case, the head can further include a channel for mounting a thermistor therein. The distal catheter assembly can be mounted to the distal end of a catheter tube to form a fully functioning catheter.
