Patent number: 8784333Abstract: Catheters, kits, and methods are provided for removing material from a body lumen. The catheters and methods may be used in a variety of body lumens, including but not limited to coronary and other arteries. In general, the catheter has a cutting element that cuts material while the material is engaged by a material capture device on the catheter body. Preferably, the material capture device tensions the material during cutting, which reduces the amount of cutting force required. The material capture device typically follows a path that draws material into the catheter body. Preferably, but not necessarily, the material capture device may be arranged on the catheter body to advance along a path outwardly from the catheter body into the material and then inwardly towards the catheter body to tension the material. The cutting element on the catheter body moves between a first position and a second position to cut the material while in tension.Type: GrantFiled: January 21, 2009Date of Patent: July 22, 2014Assignee: Covidien LPInventors: Tim Corvi, Stephen Boyd, Brett Follmer, John G. Stine, David W. Snow, Darren G. Doud

Publication number: 20030125757Abstract: A debulking catheter comprising a tissue debulking assembly for removing material from a body lumen. Catheters of the present invention generally include a catheter body having proximal and distal portions and a tissue debulking assembly disposed at least partially within the distal portion. The tissue debulking assembly is radially movable to expose at least a portion of the assembly through a window on the catheter body to contact material in the body lumen. The catheter may then be moved to allow the tissue debulking assembly to remove all or a portion of the material. In exemplary embodiments, the distal portion of the catheter body is rotatably coupled to the proximal portion such that rotation or deflection of the distal portion, relative to the proximal portion, urges the window against material in the body lumen, exposes the tissue debulking assembly through the window, or both.Type: ApplicationFiled: November 4, 2002Publication date: July 3, 2003Applicant: FOX HOLLOW TECHNOLOGIES, INC.Inventors: Himanshu Patel, John B.
