Patent number: 10022145Abstract: A method of removing material from a blood flow lumen generally includes providing a device having a cutting element and an opening, advancing the device through the blood flow lumen to a site where material is to be removed, forcing the opening toward a wall of the site where material is to be removed, and moving the cutting element and the opening so that material in the blood flow lumen is cut by the cutting element and directed into the opening for removal as the cutting element and opening are moved through the blood flow lumen. In some embodiments, the device may be deflected or bent to force the opening toward a wall to remove material. The cutting element may be rotatable and may have an axis that is movable, that is not parallel to the longitudinal axis of the device, or both.Type: GrantFiled: September 20, 2016Date of Patent: July 17, 2018Inventors: John B.

Publication number: 20040167554Abstract: A device for reentering a true lumen from a subintimal location includes a rotating cutting element and energy emitting element. Energy is emitted to determine the location of the true lumen and the cutting element is exposed to cut an access path to the true lumen. The cutting element may be gradually exposed and the distal portion may be bent or articulated to move the cutting element toward the material to be cut.Type: ApplicationFiled: April 22, 2003Publication date: August 26, 2004Applicant: Fox Hollow Technologies, Inc.Inventors: John B.

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.
