Claims
- 1. An electrode and nozzle assembly for use with an electrosurgical device comprising:
a shroud including a distal portion and a proximal portion, a channel defining a longitudinal axis and extending between the distal portion and the proximal portion, the channel being open at each end, and a port defining a lumen, the lumen communicating with the channel, the longitudinal axis of the lumen intersecting the longitudinal axis of the channel to define an acute angle; a conductive coating positioned on an internal wall of at least a portion of the channel and the lumen; an electrode positioned within the channel, the electrode having a distal end extending from the distal portion of the shroud and a proximal end extending from the proximal portion of the shroud; and an end cap positioned adjacent the proximal portion of the shroud about the electrode, the end cap being overmolded to the shroud and to the electrode.
- 2. An electrode and nozzle assembly as recited in claim 1, wherein the acute angle is between about 10 degrees and about 20 degrees.
- 3. An electrode and nozzle assembly as recited in claim 2, wherein the acute angle is about 12.6 degrees.
- 4. An electrode and nozzle assembly as recited in claim 1, wherein a recess is formed in the proximal portion of the shroud, the end cap being positioned within the recess.
- 5. An electrode and nozzle assembly as recited in claim 4, wherein at least a portion of the recess and at least a portion of the end cap have a hexagonal configuration.
- 6. An electrode and nozzle assembly as recited in claim 1, wherein a proximal end of the channel has a smaller diameter than the distal end of the channel.
- 7. An electrode and nozzle assembly as recited in claim 1, further including a dielectric tube positioned within the port.
- 8. An electrode and nozzle assembly for use with an electrosurgical device comprising:
a shroud including a distal portion and a proximal portion, the shroud defining a channel having a longitudinal axis and extending between the distal portion and the proximal portion, the channel being open at each end; a conductive coating positioned on an internal wall of at least a portion of the channel; and an electrode positioned within the channel, the electrode having a distal end extending from the distal portion of the shroud and a proximal end extending from the proximal portion of the shroud.
