A method and apparatus for treatment of pulmonary conditions, including a device having an end effector sized and shaped to contact a nerve component on the exterior of a bronchial segment and apply energy to that nerve component.

An electronic forceps system includes a handle including a pair of pivotable arms distally extending from a proximal end of the handle, at least one arm of the pair of arms having an electrically-conductive arm element connectable to a power source, wherein each arm of the pair of arms comprises a respective pair of arm interfaces, and the electrically-conductive arm element extends to at least one interface of the pair of interfaces. Also provided is a pair of tips, at least one tip of the pair of tips having an electrically-conductive tip element, wherein each tip has a tip interface configured to removably connect to a respective arm interface, each tip has a distal working surface, the electrically-conductive tip element is configured to removably and electrically connect to the electrically-conductive arm element, the electrically-conductive tip element is connected to a heater.

A surgical instrument includes a drive member movable by a drive motor between a home position and an end of stroke. A mechanical stop is disposed at or near the end of stroke and is structured to increase resistance to movement of the drive member from a first position to a second position. A control system detects a current spike associated with the increased resistance and interrupts power to the drive motor.

A method for controlling a temperature at an end-effector of an instrument connected with a controller includes estimating a residual energy associated with a prior application of base energy to the end-effector based on a first set of parameters. An amount of electric power that is converted to heat at the end-effector is estimated based on the first set of parameters. A current temperature at the end-effector is estimated based on: (i) the residual energy, (ii) the amount of electric power provided to the end-effector, and (iii) a time for which the electric power is provided. The electric power provided to the instrument is controlled to maintain the current temperature at the end-effector within a predetermined range.

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.

Tissue treatment systems include an actuator handle assembly coupled with a clamp assembly having a first jaw mechanism and a second jaw mechanism. A first jaw mechanism includes a first flexible boot, a first flexible ablation member coupled with the first flexible boot, and a first rotatable jawbone disposed within the first flexible boot. A second jaw mechanism comprises a second flexible boot, a second flexible ablation member coupled with the second flexible boot, and a second rotatable jawbone disposed within the second flexible boot.

A method of manufacturing a thermal cutting element for a surgical instrument includes manufacturing a substrate, coating at least a portion of the substrate via Plasma Electrolytic Oxidation (PEO), and disposing a heating element on at least a portion of the PEO-coated substrate. The method may further include attaching the thermal cutting element to a jaw member of a surgical instrument.

A device is described for treating a nasal airway by modifying a property of a nasal tissue of or near a nasal valve of the airway, without using a surgical incision or an implant, to decrease airflow resistance or perceived airflow resistance in the nasal airway. Various embodiments include an elongate shaft, a bipolar radiofrequency delivery member extending from one end of the shaft, and a handle attached to the elongate shaft at an opposite end from the radiofrequency delivery member. The radiofrequency delivery member is sized to be inserted into a nose and configured to at least temporarily deform the nasal tissue and deliver radiofrequency energy. The radiofrequency delivery member includes two rows of protruding electrodes disposed on a tissue contact surface, and the device is configured to deliver radiofrequency energy from one row of electrodes to the other row of electrodes.

A surgical instrument includes a movable handle movable relative a housing to manipulate an end effector assembly, and a latch assembly. The latch assembly includes a latch arm including a latch post, and a latch track defining an entry path, a latching path, a saddle, an un-latching path, and a return path. The latch post moves through the entry path, the latching path, and into the saddle upon movement of the movable handle from an un-actuated position to an over-actuated position and back to an actuated position to lock the movable handle. The latch post moves from the saddle through the un-latching path and the return path upon movement of the movable handle from actuated position to the over-actuated position and back to the un-actuated position. The return path includes a ramped surface configured to inhibit reverse travel of the latch post into the return path.

An electrosurgical forceps includes first and second shaft members pivotably coupled to one another via a pivot member such that pivoting of the first and second shaft members between spaced-apart and approximated positions pivots jaw members thereof between open and closed positions. A knife is translatable between retracted and extended positions. The knife has a stop to prevent distal movement of the knife beyond the extended position.
