## Abstract

An energy source is offset from an elongate probe axis with an extension. The amount of offset of the energy source can be controlled by varying an amount of offset of the extension. The energy source rotated and translated at the offset distance to resect tissue. In some embodiments, the probe is configured to receive a second treatment probe comprising a second energy source, in which the second energy source is rotated and translated relative to the first treatment probe, which can improve positional accuracy and stability. The energy source and the extension can be coupled to a linkage to offset the energy source, and to translate and rotate the energy source with varying amounts of offset. The linkage can be coupled to a processor and one or more of the energy source moved in accordance with a treatment profile.

## Claims

### Claim 1

A probe for treating a subject, comprising:
an energy source;
a sheath
an elongate shaft comprising an elongate axis, the elongate shaft configured to move the energy source with translation of the elongate shaft along the elongate axis relative to the sheath, the elongate shaft located within the sheath to allow rotation and translation of the energy source relative to the sheath with an extension deflected away from the elongate axis,
wherein the extension is coupled to the elongate shaft with a link to rotate the extension about the link to move the energy source away from the elongate axis with movement of the extension away from the elongate axis to offset the energy source from the elongate axis; and
a fluid supply channel and a fluid removal channel within the sheath, wherein the fluid supply channel comprises an irrigation channel and the fluid removal channel comprises an aspiration channel, wherein the fluid supply channel and the fluid removal channel are sized and shaped to engage each other within the sheath with one or more of the fluid supply channel or the fluid removal channel sized and shaped to receive the elongate shaft coupled to the energy source to allow rotation and translation of the energy source with the energy source deflected away from the elongate axis.
