20110040315Devices, systems, and methods for cutting and removing occlusive material from a body lumen - 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.02-17-2011

20110152906Devices, systems, and methods for debulking restenosis of a blood vessel - Devices, systems, and methods are employed to restore patency to arterial lesions, e.g., by debulking restenosis in a blood vessel or within a stent or coil.06-23-2011
20110152907Devices, systems, and methods for performing atherectomy including delivery of a bioactive material - 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.06-23-2011

20090069797BIPOLAR DEVICES FOR MODIFICATION OF AIRWAYS BY TRANSFER OF ENERGY - 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.03-12-2009
