Control systems and methods for delivery of energy that may include control algorithms that prevent energy delivery if a fault is detected and may provide energy delivery to produce a substantially constant temperature at a delivery site. In some embodiments, the control systems and methods may be used to control the delivery of energy, such as radiofrequency energy, to body tissue, such as lung tissue.

Control methods and devices for energy delivery

The devices and methods generally relate to treatment of occluded body lumens. In particular, the present devices and method relate to removal of the occluding material from the blood vessels as well as other body lumens.

Atherectomy devices and methods

Described here are devices and methods for performing atherectomies. Generally, the atherectomy devices may comprise a handle, a cutter assembly, and a catheter or catheter assembly therebetween. The cutter assembly may include a cutter housing and a cutter comprising a first cutting element and a second cutting element, each of which may be rotated relative to the atherectomy device to cut occlusive material.

Atherectomy apparatus systems and methods

A vascular device is provided having a catheter body and a rotatable cutter assembly located at the distal end of the catheter body. The cutter assembly has at least one helical cutting surface within a housing that is coupled by a torque shaft to a drive mechanism. A conveyor mechanism helically wound about the torque shaft conveys occlusive material conveyed into the housing by the helical cutting blade further proximally along the catheter body for discharge without supplement of a vacuum pump. The catheter body is manipulated to insert the distal end of the catheter body within a body lumen and advance the distal end of the catheter body toward the occlusive material. The drive mechanism is operated to rotate the helical cutting surface to cut and convey the occlusive material from the body lumen proximally into the housing and to convey the occlusive material conveyed into the housing by the helical cutting surface further proximally along the catheter body by the conveyor mechanism for discharge without supplement of a vacuum pump. The distal end of the catheter body is deflected and rotated to sweep the cutter assembly in an arc about the center axis of the catheter body to cut occlusive material in a region larger than the outside diameter of the cutter assembly.

Devices systems and methods for cutting and removing occlusive material from a body lumen

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

This relates to treating airways in a lung to decrease asthmatic symptoms. The also includes steps of measuring a parameter of an airway at a plurality of locations in a lung, identifying at least one treatment site from at least one of the plurality of locations based on the parameter, and applying energy to the treatment site to reduce the ability of the site to narrow.

Methods for treating airways

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.
