Abstract

Disclosed embodiments include apparatuses, systems, and methods for positioning electrodes within a body. In an illustrative embodiment, an apparatus for slidably moving multiple features relative to a sheath insertable into a body and positionable relative to a reference point includes a primary actuator configured to move a primary electrode to a first position. A secondary actuator is configured to move a secondary electrode to a second position. A shrouding device is configured to selectively prevent access to the secondary actuator until the primary actuator has been manipulated to extend the primary electrode to the first position.

Claims (29)

1. A method of preparing electrodes for ablative electrical treatment of tissue at a reference point, the method comprising:

moving a primary actuator in a distal direction along a longitudinal axis, the primary actuator configured to move a primary electrode to a first location near the reference point and concurrently move a secondary electrode;

moving the primary actuator to move a shrouding device to permit access to a secondary actuator configured to move a secondary electrode; and

moving the secondary actuator to move the secondary electrode to a second location near the reference point.

2. The method of claim 1 , wherein moving the primary actuator to move the shrouding device includes rotating the primary actuator about the longitudinal axis and relative to the secondary actuator.

3. The method of claim 1 , wherein moving the primary actuator to move the primary electrode includes slidably moving the primary actuator and moving the secondary actuator to move the secondary electrode includes slidably moving the secondary actuator.

4. The method of claim 1 , further comprising locking the primary actuator to maintain the primary electrode at the first location.

5. The method of claim 1 , further comprising locking the secondary actuator to maintain the secondary electrode at the second location.

6. The method of claim 1 , further comprising moving the primary actuator away from a front end of an outer housing to partially retract the primary electrode to a third location relative to the reference point.

7. A method of preparing electrodes for ablative electrical treatment of tissue at a reference point, the method comprising:

inserting a primary electrode and a secondary electrode, wherein the secondary electrode is contained within the primary electrode and is initially coupled to move with the primary electrode, into a patient to a position adjacent the reference point;

actuating a primary actuator coupled to the primary electrode to move the primary electrode into a first location to apply treatment to the reference point;

manipulating the primary actuator to expose a secondary actuator coupled with the secondary electrode to permit access to the secondary actuator; and

actuating the secondary actuator to move the secondary electrode to a second location near the reference point.

8. The method of claim 7 , wherein moving the primary actuator to move the primary electrode includes slidably moving the primary actuator and moving the secondary actuator to move the secondary electrode includes slidably moving the secondary actuator.

9. The method of claim 7 , wherein moving the primary actuator to move the primary electrode to the first location causes the secondary actuator to move the secondary electrode to move in concert with the primary electrode.

10. The method of claim 7 , wherein manipulating the primary actuator to expose the secondary actuator includes rotating the primary actuator to expose the secondary actuator that was previously covered by the primary actuator.

11. The method of claim 7 , further comprising:

after the secondary actuator is moved to move the secondary electrode to the second location, the primary electrode is rotated back to an initial position at least partially covering the secondary electrode; and

moving the primary actuator coupled with the primary electrode to at least partially retract the primary electrode away from the reference point.

12. The method of claim 7 , further comprising releasing a primary actuator lock in order to enable movement of the primary actuator.

13. The method of claim 7 , further comprising engaging a slidable actuator lock to maintain the secondary electrode in the second location.

14. A method of manipulating electrodes for ablative electrical treatment of tissue at a reference point, the method comprising:

manipulating a primary actuator grip within a channel defined in an outer handle to move a primary actuator to move a primary electrode to a first location near the reference point;

rotating the primary actuator grip to move a shrouding structure and expose a secondary actuator grip within the channel to enable movement of a secondary actuator configured to move a secondary electrode; and

moving the secondary actuator grip within the channel to move the secondary electrode to a second location near the reference point.

15. The method of claim 14 , further comprising releasing a primary actuator lock in order to enable movement of the primary actuator.

16. The method of claim 15 , further comprising, with the primary electrode in the first location, locking the primary actuator lock to maintain the primary electrode in the first location.

17. The method of claim 14 , wherein manipulating the primary actuator grip within the channel includes sliding the primary actuator grip within the channel.
