CLAIMS

We claim:

1. A medical system comprising:

an insertion device including a handle and a delivery portion;

a laser fiber, wherein the laser fiber extends through the insertion device and is coupled to a laser slider to control a position of the laser fiber relative to a distal end of the delivery portion;

a conductive wire, wherein the conductive wire extends through the insertion device and is coupled to a wire slider to control a position of the laser fiber relative to a distal end of the delivery portion; and

a lock positioned within the handle, wherein the lock is movable in order to selectively lock either the movement of the laser slider or the movement of the wire slider.

2. The medical system of claim 1, wherein the lock includes first and second side arms.

3. The medical system of claim 2, wherein, in a first configuration, a first side arm extends from a first side of the handle and a second side arm is within or aligned with a second side of the handle opposite to the first side, and

wherein, in a second configuration, the second side arm extends from the second side of the handle and the first side arm is within or aligned with the first side of the handle.

4. The medical system of claim 3, wherein the lock includes a forward arm and a rear arm.

5. The medical system of claim 4, wherein the forward arm and the rear arm are laterally offset from one another.

6. The medical system of claim 5, wherein in the first configuration, the forward arm blocks the wire slider from moving distally in order to limit distal movement of the conductive wire and allows the laser slider and the laser fiber to move distally.

7. The medical system of claim 6, wherein in the second configuration, the rear arm blocks the laser slider from moving distally in order to limit distal movement of the laser fiber and allows the wire slider and the conductive wire to move distally.

8. The medical system of claim 7, further including a spring within the handle to bias distal movement of the wire slider.

9. The medical system of claim 8, wherein the wire slider includes a rod portion that extends distally through a portion of the spring, and wherein the rod portion limits the distal extension of the wire slider.

10. The medical system of any preceding claim, wherein the laser fiber includes a distal end cap to direct laser energy.

11. The medical system of claim 10, wherein the distal end cap includes a side opening to form a side-fire distal end.

12. The medical system of any preceding claim, wherein the laser slider is movably positioned on a top portion of the handle, and wherein the wire slider is movably positioned on a bottom portion of the handle.

13. The medical system of any preceding claim, wherein a proximal end of the laser fiber is configured to be coupled to a laser energy source, and

wherein a proximal end of the conductive wire is configured to be coupled to an electrical energy source.

14. The medical system of claim 13, further including:

a first actuator configured to control the delivery of laser energy from the laser energy source to the laser fiber; and

a second actuator configured to control the delivery of electrical energy from the electrical energy source to the conductive wire.

15. The medical system of claim 14, wherein the laser fiber is configured to deliver up to 180W of 532nm light.
