Abstract
An ablation instrument comprises an elongate shaft having a cannula channel and a scope channel, and an electrode disposed in the cannula channel. The electrode is slidable between a first position in which a distal end of the electrode is contained within the cannula channel, and a second position in which the distal end of the electrode extends out of a distal opening of the cannula channel. The ablation instrument further comprises a distal head coupled to the elongate shaft and configured for engaging tissue.
Claims19
An ablation instrument, comprising:
- an elongate shaft having a cannula channel, a suction channel, and a scope channel;
- an electrode disposed in the cannula channel, wherein the electrode is slidable between a first position in which a distal end of the electrode is contained within the cannula channel, and a second position in which the distal end of the electrode extends out of a distal opening of the cannula channel;
- a distal head coupled to the elongate shaft and configured for engaging tissue, wherein the distal head comprises a plurality of suction apertures in fluid communication with the suction channel, wherein the suction apertures are arranged to hold tissue when suction is applied, the distal head further comprises a flat face and an angled face, each of the faces including at least one of the suction apertures;
- and
- a baffle member located in the suction channel, wherein the baffle member forms a barrier between a portion of the suction channel adjacent the flat face, and a portion of the suction channel adjacent the angled face.

An ablation instrument, comprising:
- an elongate shaft having a cannula channel, a suction channel, and a scope channel;
- an electrode disposed in the cannula channel, wherein the electrode is slidable between a first position in which a distal end of the electrode is contained within the cannula channel, and a second position in which the distal end of the electrode extends out of a distal opening of the cannula channel;
- and
- a distal head coupled to the elongate shaft and configured for engaging tissue, wherein the distal head comprises a suction face comprising a plurality of suction apertures in fluid communication with the suction channel, wherein the suction apertures are arranged to hold tissue when suction is applied, the scope channel extends at a non-zero angle α to the suction face, such that the angle α results in an increased separation between a scope positioned in the scope channel and the suction face when the scope is advanced from a distal opening of the scope channel.

An ablation instrument, comprising:
- an elongate shaft having a cannula channel and a scope channel;
- an electrode disposed in the cannula channel, wherein the electrode is slidable between a first position in which a distal end of the electrode is contained within the cannula channel, and a second position in which the distal end of the electrode extends out of a distal opening of the cannula channel;
- and
- a distal head coupled to the elongate shaft and configured for engaging tissue;
- and
- a handle assembly attached to the elongate shaft, wherein the handle assembly includes a sliding mechanism shaped to receive and manipulate a scope, wherein the sliding mechanism includes a cutout configured to receive a feature on a scope, such that rotation of the scope relative to the instrument is prevented when the feature is received in the cutout.

An ablation instrument, comprising:
- an elongate shaft having a cannula channel and a scope channel;
- an electrode disposed in the cannula channel, wherein the electrode is slidable between a first position in which a distal end of the electrode is contained within the cannula channel, and a second position in which the distal end of the electrode extends out of a distal opening of the cannula channel;
- a distal head coupled to the elongate shaft and configured for engaging tissue;
- and
- a handle assembly attached to the elongate shaft, wherein the handle assembly includes a sliding mechanism shaped to receive and manipulate a scope, wherein the sliding mechanism defines a portion of the scope channel and is slidable to manipulate a longitudinal position of a scope disposed in the scope channel relative to the instrument between (i) a distal position in which a distal end of the scope is distal of a distal end of the distal head, and (ii) a retracted position in which the distal end of the scope is within the scope channel.
