An electrode instrument, a surgical handheld device and a production method, by means of which the quality of the aforementioned instruments can be improved. This is achieved by virtue of an electrode instrument for a surgical handheld device having an electrical conductor which is electrically insulated by an insulation in the form of flexible tubing, wherein the conductor is pressed in an electrode carrier, wherein the electrode carrier has a cross section with six pressed sides at the pressed position.

A method for ablating target tissue includes the steps of: (a) delivering an ablation balloon catheter to the target tissue, wherein the ablation balloon catheter includes a compliant balloon, a visualization device; and an electrode array that is visible to the visualization device, each electrode being configured to deliver ablation energy, wherein the electrode array is independently movable relative to the compliant balloon; (b) isolating the target tissue such that at least one electrode of the electrode array is in contact with the target tissue; and (c) delivering the ablation energy to those electrodes of the electrode array that are confirmed, using the visualization device, to be in contact with target tissue.

Disclosed embodiments include apparatuses, systems, and methods for positioning electrodes within a body. In an illustrative embodiment, a control handle is selectively engageable with primary and secondary actuators respectively coupled with primary and secondary electrodes. At a first position, the primary and secondary actuators are movably engaged to move in concert to a second position where distal ends of the electrodes extend into a target region. At the second position, the control handle is engaged with the secondary actuator and movable independently of the primary actuator in a first direction to a third position where the distal end of the secondary electrode extends beyond the distal end of the primary electrode. At the third position, the control handle is movably engaged with the primary actuator and movable independently of the secondary actuator in a second direction to a fourth position to partially retract the distal end of the primary electrode.

An electroporation probe that includes an injection means, allowing a single electroporation probe to be used for both the electroporation of cells and the injection of a fluid. The electroporation probe having (a) a probe body having an interior channel, a first end, and a second end; (b) a plurality of perforations in the probe body proximal the second end; (c) a sleeve positioned within the interior channel, wherein the sleeve is moveable between a first position sealing the perforations and a second position opening the perforations; (d) a connection between the probe body and an electroporation machine, wherein the probe body is in electrical communication with the electroporation machine; and (e) a tubing in fluid communication with the interior channel, wherein fluid injected into a proximal end of the tubing is exitable through the perforations when the sleeve is in the second position.

A device and method for cutting or ablating tissue in a human or veterinary patient includes an elongate probe having a distal end, a tissue cutting or ablating apparatus located adjacent within the distal end, and a tissue protector extending from the distal end. The protector generally has a first side and a second side and the tissue cutting or ablating apparatus is located adjacent to the first side thereof. The distal end is structured to be advanceable into tissue or otherwise placed and positioned within the patient's body such that tissue adjacent to the first side of the protector is cut away or ablated by the tissue cutting or ablation apparatus while tissue that is adjacent to the second side of the protector is not substantially damaged by the tissue cutting or ablating apparatus.

A jaw member of an electrosurgical instrument includes a U-shaped structural frame defining a cavity therein and extending therealong configured to receive at least a portion of an insulative spacer therein such that the insulative spacer extends distally therefrom. The insulative spacer includes a tapered fin at a distal end thereof. A tissue treating plate is disposed on the face of the insulative spacer, the tissue treating plate is adapted to connect to a source of energy to treat tissue therewith. The tapered fin is configured to extend to and support a distal end of the tissue treating plate.

A deployment mechanism for selectively deploying and retracting an energizable member and/an insulative member relative to an end effector assembly of a surgical instrument includes one or more actuators, a clutch assembly, and a drive assembly. The clutch assembly is configured to couple to the actuator(s) to provide rotational motion in the first direction in response to such rotation of the actuator(s) and to decouple from the actuator(s) in response to rotation thereof in the second direction. The drive assembly is operably coupled to the clutch assembly and is configured to convert the rotational motion provided by the clutch assembly into longitudinal motion to translate the energizable member and/or insulative member from a storage position to a deployed position and to translate the energizable member and/or the insulative member from the deployed position back to the storage position.

A medical device for performing a hysterectomy is provided. The medical device has a tissue incision assembly that includes a first cup nested within a second cup. The tissue incision assembly also includes a spacer assembly between the first cup and the second cup in order to maintain a spacing between the first and second cups. The tissue incision assembly also has a cutting implement that has a portion extending between, and movable with respect to, the first and second cups. The cutting implement can provide a circular cut guided via the spacing between the first and second cups.
