Systems and related methods for identifying and/or ablating targeted nerves are provided. A probe with stimulating electrodes and/or ablation members are provided. The probe may be inserted into a nasal cavity and current may be introduced through the electrodes to stimulate a targeted area. The response to stimulation may be used to identify the targeted nerve. Once identified, the ablation member may ablate the targeted nerve.

This invention relates to a cautery instrument or handheld device having a generally centralized lumen or passageway through the device and that utilizes a conductive tubular member.

The present invention relates to a suction structure for an electrosurgical handpiece and particularly to a smog suction structure for a handpiece, the smog suction structure being capable of efficiently suctioning and removing smog which obstructs the view of an operating surgeon and has a harmful effect on health.

Lysing surgical instruments and related systems and methods. In some embodiments, the instrument may comprise a lysing tip comprising at least one bead. The at least one bead may comprise an at least substantially electrically non-conductive surface and at least one lysing member defining at least one lysing segment extending within a recess defined, at least in part, by the at least one bead. The at least one bead may also protrude both distally and proximally relative to the at least one lysing member.

An electrosurgical system includes an electrosurgical unit electrically coupled to a surgical retractor. The electrosurgical unit includes an RF output and an RF return. The surgical retractor includes a return pad electrically coupled to the RF return of the electrosurgical unit. The electrosurgical unit includes an RF output configured to be coupled to an electrosurgical device, such as an electrosurgical device configured in a monopolar mode. A controller is configured to determine an impedance in tissue at a surgical area electrically disposed between the RF output and the and the RF return. The surgical retractor includes a handle and a blade configured to interface with tissue. The blade includes a return electrode.

A device for occlusion of a left atrial appendage of a heart including an implantable occlusion apparatus including a radially expansible element adjustable between a contracted orientation for transluminal delivery and a deployed orientation configured to occlude the left atrial appendage, an elongated catheter member operably and detachably attached to the implantable occlusion apparatus and configured for transluminal delivery and deployment of the occlusion apparatus in the left atrial appendage, and an energy delivery module configured for adjustment from a contracted configuration, and a deployed configuration suitable for engagement with adjacent tissue to ablate the tissue. The energy delivery module is operably attached to the elongated catheter member proximally of the radially expansible element and configured to contact and ablate a wall of the left atrium surrounding an ostium of the left atrial appendage.

The invention is a system and method of minimally invasive treatment with wire structure electrodes dispensed without open cut downs or laparoscopy and using energy forms including radiofrequency, microwave, direct current, and high intensity focused ultrasound.

A bipolar forceps includes a mechanical forceps including first and second shafts each having a jaw member extending from a distal end thereof and a handle disposed at a proximal end thereof for effecting movement of the jaw members relative to one another about a pivot. A disposable housing is configured to releasably couple to at least one of the shafts and an electrode assembly is associated with the disposable housing. The electrode assembly includes electrodes releasably coupleable to the jaw members. At least one of the electrodes includes a knife channel configured to receive a knife blade therethrough to cut tissue grasped between the jaw members. A switch is configured to initiate delivery of electrosurgical energy from the source of electrosurgical energy to the electrodes. An actuation mechanism is configured to selectively advance the knife blade through the knife channel to cut tissue.

The disclosed embodiments relate to an electrosurgical system, to a method for operating an electrosurgical system, and to an electrode for an electric surgical system. An image detection system of the surgical instrument detects an image of the electrode. The corresponding image data is compared with data sets in a database, in which an identifying feature of the electrode and at least one operating parameter for the electrode are assigned to each other. After the electrode type has been identified, the corresponding operating parameters are transmitted to a controller of the surgical instrument.
