Methods and devices for treating nasal airways are provided. Such devices and methods may improve airflow through an internal and/or external nasal valve, and comprise the use of mechanical re-shaping, energy application and other treatments to modify the shape, structure, and/or air flow characteristics of an internal nasal valve, an external nasal valve or other nasal airways.

An electrosurgical forceps comprising: (a.) a pair of working arms comprising; (i.) a first working arm and a second working arm, each of the first working arm and the second working arm having an inner surface; (ii.) one or more electrodes located on the inner surface of the first working arm, the second working arm, or both; and (b.) a selectively engageable activation system comprising; (i.) a control unit; (ii.) an activation switch; and (iii.) a disengagement mechanism; wherein the first working arm and the second working arm are laterally movable relative to each other so that the activation switch is actuated when the disengagement mechanism is in an engaged position by closing the first working arm and the second working arm together, sending a signal to the control unit, which in turn sends a therapy signal to the one or more electrodes; wherein when the disengagement mechanism is in a disengagement position and the working arms are closed, the therapy signal is prevented from being sent from the control unit to the one or more electrodes.

A method for reshaping a nasal airway in a patient involves advancing an inflatable balloon of a reshaping device in an uninflated configuration into a nostril of the patient and between a nasal septum and a lateral wall of the nasal airway. The method then involves inflating the inflatable balloon to an inflated configuration to cause the inflatable balloon to contact nasal mucosa covering the nasal septum and the lateral wall, delivering energy from an energy delivery member attached to or inside of the inflatable balloon, and removing the reshaping device from the nasal airway.

Provided is a high frequency hyperthermia device which includes a main body (110) which includes a high frequency generator (114) which generates high frequency currents using drive power, a hand piece (120) which is connected to the main body (110) through a cable (140) and in which a handle (121) to be gripped by a user is disposed on an upper portion of the hand piece (120), and four or more contact electrodes (122), through which the high frequency currents being supplied are applied to skin (S) in contact with the contact electrodes (122) to generate deep heat in an internal body, are disposed on a lower surface of the hand piece (120), and an alternating switch (130) which is disposed between and connected to the high frequency generator (114) and the contact electrodes (122) in a circuit manner and which supplies the high frequency currents output from the high frequency generator (114) to the contact electrode (122), wherein the contact electrodes (122) are divided into pairs each having two contact electrodes (122), and the high frequency currents are alternately supplied to the pairs at a first speed.

A surgical instrument comprises a shaft assembly comprising a shaft and an end effector coupled to a distal end of the shaft; a handle assembly coupled to a proximal end of the shaft; a battery assembly coupled to the handle assembly; a radio frequency (RF) energy output powered by the battery assembly and configured to apply RF energy to a tissue; an ultrasonic energy output powered by the battery assembly and configured to apply ultrasonic energy to the tissue; and a controller configured to, based at least in part on a measured tissue characteristic, start application of RF energy by the RF energy output or application of ultrasonic energy by the ultrasonic energy output at a first time.

An electrosurgical pencil includes a housing having proximal and distal ends, the proximal end adapted to connect to an energy source and the distal end adapted to receive an end effector assembly therein, the end effector assembly defining a surface area along a length thereof. An activation switch is operably associated with the housing and is configured to deliver electrosurgical energy to the end effector assembly upon actuation thereof. An air control valve is operatively coupled to the activation switch and is configured to simultaneously deliver a gas from a gas source to the surface area around the end effector upon actuation of the activation switch. One or more vents are defined in the distal end of the housing and are configured to direct the gas towards the surface area of the end effector.

An electrosurgical instrument includes a housing, an elongated shaft, and an end-effector assembly. The proximal end of the shaft is operably associated with the housing. The end-effector assembly is operably coupled to the distal end of the shaft and includes first and second jaw members. Each of the first and second jaw members includes a sealing plate and a bipolar electrode. Either one or both of the first and second jaw members is movable from a position in spaced relation relative to the other jaw member to at least one subsequent position wherein the sealing plates cooperate to grasp tissue therebetween. The electrosurgical instrument includes a semiconductor switch operably coupled to at least one of the sealing plates and at least one of the bipolar electrodes. The semiconductor switch is configured to enable user selection between energizing the at least one sealing plate or the at least one bipolar electrode.

Present disclosure provides a cooling device with safety features and methods for controlling temperature of the cooling device for safe cooling of target surface.

An illuminated energy device comprising a handle, an illumination element coupled to the handle and disposed continuously and circumferentially about an electrosurgical tip, the electrosurgical tip at a distal end of the handle. The illumination element is preferably adjustably coupled to the handle, and adjustment of the illumination element moves a distal end of the illumination element closer to or further away from a target such as tissue in a surgical field.

A surgical instrument includes a switch base, a power bus coupled to the switch base, an electrical lead coupled to the power bus, an actuator operatively engaged with the power bus, an actuator operatively engaged with the power bus, a membrane, and a housing. The switch base has top, bottom, and side surfaces. The membrane is disposed over the top surface of the switch base and over the power bus to seal the top surface of the switch base. The housing defines proximal and distal ends and a switch base cavity between the proximal and distal ends. The housing includes bulkheads that form a plurality of fluid impermeable seals that are disposed adjacent one of the proximal and distal ends. The fluid impermeable seals are configured to deter fluid from penetrating a proximal portion of the switch base cavity within which the electrical lead is coupled to the power bus.
