In an example, a method for delivering an anesthetic agent to a target tissue in a nasal cavity of a patient includes inserting a cryotherapy device into the nasal cavity of the patient. The cryotherapy device includes a cryotherapy delivery feature and one or more protrusions. The method also includes positioning the cryotherapy delivery feature in contact with the target tissue, and delivering, using the cryotherapy delivery feature, a cryotherapy treatment to the target tissue. After inserting the cryotherapy device into the nasal cavity, the method includes actuating the one or more protrusions from a retracted state to an extended state. After actuating the one or more protrusions to the extended state, the method includes penetrating the target tissue with the one or more protrusions. After penetrating the target tissue, the method includes delivering, via the one or more protrusions, an anesthetic agent into the target tissue.

A cosmetic method for treating a skin of a person is presented, the method comprises inserting one or more needles to one or more depths into the skin of the person such that at least a tip of at least one needle of the one or more needles is deployed within a muscle layer of the person's skin; applying a negative DC voltage to the one or more needles, while a skin of the person is in contact with a positive electrode to form one or more closed circuits of DC current through the person's body; and providing the DC current for a pre-selected amount of time to damage and/or ablate muscles and/or muscle nerve cells in the muscle layer; thereby providing a skin treatment comprising reducing and/or smoothing wrinkles from the person's skin.

A surgical cautery device, system, and method of use may apply bipolar and/or sesquipolar electrocautery to target tissue via a pair of instruments with other primary surgical functions. The surgical cautery device and system may include first and second elements capable of forming an electrical circuit. The second element may be independently positionable with respect to the first element. The first and second elements may also include a surgical component with an independent surgical function. Exemplary surgical components include a rotary blade, a cutting tool, a grasper tool, a micro-scissors tool, a micro-grasping forceps tool, a dissector, a micro-dissector, curette, and a suction cannula. On some occasions, one of the surgical components may be interchangeable with another surgical component.

An electrosurgical tool for conveying electrical energy comprising an elongated electrode extending in an axial direction from a proximal electrode end to a distal electrode end. The distal electrode end defining a working end configured for cutting or coagulation of tissue by way of electrical energy received by the electrosurgical tool. At least one layer of an insulation material covering an outer surface of the working end so that a portion of the outer surface of the working end is not covered by the insulation material. When electrical energy is provided to the elongated electrode, current is only conducted through an exposed portion of the outer surface of the working end. At least one layer of the insulation material prevents current from straying from the outer surface of the working end covered with the insulation material.

A medical apparatus includes a probe, which includes an insertion tube configured for insertion into a body cavity of a patient, a distal structure connected distally to the insertion tube and including a plurality of electrodes, which are configured to contact tissue within the body, and temperature sensors fixed to the distal structure and configured to output signals indicative of a temperature of the tissue contacted by the electrodes. The apparatus further includes an electrical signal generator configured to apply between one or more pairs of the electrodes bipolar pulses having an amplitude sufficient to cause irreversible electroporation (IRE) in the tissue contacted by the spines, and a controller configured to control a timing of the bipolar pulses applied by the electrical signal generator responsively to the signals output by the temperature sensors.

An RF ablation cannula includes a cannula shaft; an active tip as part of, or coupled to, the cannula shaft; a cannula hub coupled to the cannula shaft, the cannula hub including at least a first cannula contact and a second cannula contact, wherein the first cannula contact is electrically coupled to the active tip; and a wire extending along the cannula shaft and attached to the active tip or cannula shaft to form a thermocouple, wherein the wire is electrically coupled to the second cannula contact. As an addition to, or an alternative to, the cannula contacts, the cannula hub can include a connector with connector pins or contacts coupled to the active tip and wire.

A surgical instrument comprising a shiftable transmission is disclosed. The transmission comprises a mechanism for assuring that the transmission is in one of a plurality of predefined configurations.

A system for delivering energy to a patient's body includes a plurality of probes for delivering at least one of electrical or radiofrequency energy to the patient's body and a controller communicatively coupled to the plurality of probes and configured to present a display including a collapsible control panel that overlays a plurality of independent control panels each indicating one or more real-time operating parameters associated with the plurality of probes. The collapsible control panel includes a first graphical element for starting a treatment procedure for all of the plurality of probes simultaneously and a second graphical element that, when selected by the user, causes the display to dynamically update by closing the collapsible control panel to present third graphical elements in each of the plurality of independent control panels, the third graphical elements configured to start an individual treatment procedure for an associated one of the plurality of probes.

An electrosurgical device (10) is provided that is operable to deliver microwave energy within a controlled angular expanse to cause targeted tissue ablation. The device (10) comprises a blocking or reflecting material such as cylindrical members (34) that are laterally spaced from the antenna (20) that is operable to emit the microwave energy. The reflecting material creates regions in and/or surrounding the device into which sensors (51), such as thermocouple wires, may be placed to monitor a condition associated with the device or the patient's body.

The disclosure provides a method of manufacturing a flexible circuit electrode assembly and an apparatus manufactured by said method. According to the method, an electrically conductive sheet is laminated to an electrically insulative sheet. An electrode is formed on the electrically conductive sheet. An electrically insulative layer is formed on a tissue contacting surface of the electrode. The individual electrodes are separated from the laminated electrically insulative sheet and the electrically conductive sheet. In another method, a flexible circuit is vacuum formed to create a desired profile. The vacuum formed flexible circuit is trimmed. The trimmed vacuum formed flexible circuit is attached to a jaw member of a clamp jaw assembly.
