Abstract
In a catheter system and method for controlling such a system, an elongate hollow shaft has a proximal end connected to a handle and a distal end remote from the handle. A working component is carried by the shaft and has at least one characteristic that is adjustable. An actuator is rotatably mounted on the handle for selectively adjusting at least one characteristic of the working component. A control line extends at least in part within the shaft. The control line operatively couples the actuator with the working component such that rotation of the actuator relative to the handle effects linear translation of the control line to adjust the at least one characteristic of the working component.
Claims10
A catheter system comprising:
- a handle,
- an elongate hollow shaft having a proximal end connected to the handle and a distal end remote from the handle,
- a working component carried by the shaft and having at least one characteristic that is adjustable;
- an actuator rotatably mounted on the handle for selectively adjusting at least one characteristic of the working component;
- and
- a control line extending at least in part within the shaft, the control line operatively coupling the actuator with the working component such that rotation of the actuator relative to the handle effects linear translation of the control line to adjust the at least one characteristic of the working component.
The catheter system of claim lwherein the electrode component comprises a multiple electrode component.
A method of controlling a catheter system of the type having a handle and a working component operatively coupled to the handle by a control line, the method comprising:
- rotating an actuator relative to the handle, and
- acting on the control line in response to rotation of the actuator to effect linear translation of the control line, the linear translation of the control line adjusting at least one characteristic of the working component.
