Systems and methods for delivering energy to passageways in a patient, such as airways in the lung of a patient for treating asthma. One embodiment of a method for delivering energy to a passageway comprises positioning an access device in a lung airway of a patient and advancing an elongated body of a treatment device along the access device until an energy delivery unit at a distal portion of the elongated body projects from the access device. The method can further include expanding the energy delivery unit such that energy delivery elements contact a sidewall of the airway and activating an energy supply coupled to the treatment device such that energy is delivered to the sidewall of the airway. A single person physically operates both the access device and the treatment device while expanding the energy delivery unit and activating the energy supply.

Systems and methods for delivering energy to passageways in a patient

This relates to methods and devices for achieving contact between the wall of a cavity or passageway and a medical device when used in tortuous anatomy.

Energy delivery devices and methods

An energy delivery device is disclosed. The energy delivery device may include an elongate member having a proximal end and a distal end, and an energy emitting portion coupled to the distal end of the elongate member. The energy emitting portion may be configured to transition between a first, collapsed configuration and a second, expanded configuration. In addition, the energy emitting portion may include a plurality of legs forming a basket, such that when the energy emitting portion is in the second, expanded configuration a central portion of at least one of the legs includes a substantially straight configuration.

Electrodes for tissue treatment

A medical device for treating an airway of a patient. The medical device may include an elongate tubular member having a proximal end, a distal end, and a lumen extending therebetween. The medical device may also include a plurality of conductive elements disposed on a surface of the elongate tubular member. In some embodiments, at least one of the plurality of conductive elements may be disposed distally of another of the plurality of conductive elements. In addition, each of the plurality of conductive elements may be electrically coupled to a surface of the lumen. The medical device may also include a piston movably disposed within the lumen. The piston may include a distal portion configured to make electrical contact with one or more of the plurality of conductive elements.

Medical device for treating airways and related methods of use

An energy delivery device for treating tissue regions in a body conduit, such as a lung airway, may utilize one or more markers, rings, bands, or other visual indicators along an outer surface of the device body. The one or more visual indicators facilitate guidance of the device to effectively and efficiently treat the tissue according to a predetermined axial treatment as well as measure extension of a distal portion of the device, tissue length, and/or treatment length. The predetermined axial treatment may be contiguous, overlapping, or intermittently spaced apart as determined by the marker spacing distance.
