Methods and devices for treating reversible chronic obstructive pulmonary disease are disclosed, which include a device for delivering energy to a wall of an airway in a human lung. The device includes a flexible elongate body with a proximal portion, a distal portion, a distal end, and a lumen extending therebetween. The device also includes a deployment member having an electrically conducting wire extending from the proximal portion of the elongate body and extending through the lumen and terminating at a distal tip distal to the distal end of the elongate body. The device further includes an expandable basket having a plurality of curved electrode legs and a temperature sensing element coupled to the expandable basket.

This relates to treating an asthmatic lung and more particularly, relates to advancing a treatment device into the lung and treating the lung with the device. This also includes additional steps of treating the airway wall, applying energy or heat to the airway wall in an asthmatic lung.

摘要:
Devices, systems, and methods are employed to perform an atherectomy in an identified region to restore patency to arterial lesions. A bioactive material is introduced into the identified region before, after or during performing the atherectomy. The bioactive material can be introduced, e.g., on a balloon coated with the bioactive material, which is expanded in contact with the identified region to deliver the bioactive material. The bioactive material can be, e.g., at least one of a restenosis-inhibiting agent, a thrombus-inhibiting agent, and an anti-inflammatory agent.

This relates to a device for treating lung disease, and more particularly, relates to a device for exchanging energy with airway tissue such as that found in the airways of human lungs. The exchange of energy with this airway tissue in the airways reduces the ability of the airways to constrict and/or reduces the resistance within the airway to the flow of air through the airway.

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. In some variations, the devices include a catheter body, a cutter assembly, a drive mechanism, a torque shaft, a conveyor mechanism, a deflecting mechanism and a torque control device. The deflecting mechanism may be slidable within the catheter body to point the cutter assembly toward a side of a body lumen. The torque control device may sweep the cutter assembly in an arc when the cutter assembly is deflected.
