A novel microwave ablation applicator includes a flexible tubular shaft and a partially encapsulated antenna. The applicator is adapted to be used with an endoscope in order to access remote targets deep within an organ of a patient. Microwave power is emitted from the antenna in a desired radiation pattern by circulating an attenuating liquid through the shaft and across a portion of the antenna. Microwave ablation systems and methods are described.

Methods and devices for diagnosing, monitoring, and/or treating tissue through an opening or port through an airway wall are provided herein.

Methods and devices for diagnosing, monitoring, or treating medical conditions through an opening through an airway wall

A medical appliance for use in medical procedures to controllably advance a medical device through a sheath. The medical appliance features pneumatic action and connecting structures adapted to couple the appliance to a variety of types of catheters, tools, and instruments.

An electrosurgical access catheter for assisting a physician perform an ancillary surgical procedure on a region of interest (ROI) in a patient has a tubular shaped elongate shaft and a ring-shaped active electrode located at the distal end. A passageway extends from the proximal section to the distal end of the shaft, and through the ring-shaped active electrode. The proximal section of the elongate shaft is detachably coupled to an electrosurgical controller such that the ring-shaped active electrode is operable with the electrosurgical controller and a dispersive electrode to electrosurgically make a circular-shaped incision through a tissue wall, carving a cylindrical-shaped tissue plug as the ring-shaped active electrode is advanced through the wall. The access sheath is advanced through the surgically created opening and without further dilation of the opening. The invention has particular applicability to the lung, and minimally invasive bronchoscopic procedures. Related methods are also described.

A treatment of obstructive lung disease includes aiming a condensable vapor towards the airway wall, causing a band-shaped lesion to grow to a depth into the airway wall. Ablation parameters are set to control the depth of the band-shaped lesion to encompass the epithelial layer and exclude the smooth muscle layer of the airway. A wide variety of configurations of the vapor delivery are described to create ablation patterns in the airways of the patient with particular emphasis on treating chronic bronchitis.

Vapor ablation treatment of obstructive lung disease

A method for treating the lung during an acute episode of reversible chronic obstructive pulmonary disease such as an asthma attack. The method comprises transferring energy to an airway wall of an airway such that a diameter of the airway is increased. The energy may be transferred to the airway wall prior to, during or after an asthma attack. The energy may be transferred in an amount sufficient to temporarily or permanently increase the diameter of the airway. The method may be performed while the airway is open, closed or partially closed.

Methods for treating a lung

Methods, devices, and systems are described herein that allow for improved sampling of tissue from remote sites in the body. A tissue sampling device comprises a handle allowing single hand operation. In one variation the tissue sampling device includes a blood vessel scanning means and tissue coring means to excise a histology sample from a target site free of blood vessels. The sampling device also includes an adjustable stop to control the depth of needle penetration. The sampling device may be used through a working channel of a bronchoscope.

Tissue sampling devices, systems and methods

Methods and devices for diagnosing, monitoring, and/or treating tissue through an opening or port through an airway wall. A passageway is created extending from the airway to the target tissue. The passageway provides local access to the target tissue for treatment instruments and for delivering agents.

An embodiment of the disclosure includes a method for treating a lung. The method may include inserting a cooling element into an airway of the lung; and damaging tissue disposed radially outward of surface tissue defining the airway via the cooling element.

System for treating a lung

An energy delivery device may include an elongate member having a proximal portion, a distal portion, and a lumen extending therebetween. The device may include a deployment member extending through the lumen toward a distal tip of the energy delivery device, and an expandable basket having a plurality of curved electrode legs. Each of the curved electrode legs may have a first end coupled to the distal portion of the elongate member and a second end coupled to the deployment member, and each of the plurality of curved electrode legs may have at least one energy insulated region and one energy active region. The device also may include at least one temperature sensing element coupled to said expandable basket.
