Publication number: 20050222663Abstract: A method of removing material from a blood flow lumen includes providing a device having a cutting element and an opening, the cutting element being movable relative to the opening. The method then includes advancing the device through a patient's vascular system to the blood flow lumen. Finally, the method involves moving the cutting element and the opening relative to the blood flow lumen so that a continuous piece of material is severed by the cutting element and directed into the opening as the cutting element and opening move through the blood flow lumen, the continuous piece of severed material being directed into the device for removal from the patient. The method may include providing a device having a rotatable cutter that, in some embodiments, is not parallel to the longitudinal axis of the device, is movable, has retracted and deployed positions, or any combination thereof.Type: ApplicationFiled: December 14, 2004Publication date: October 6, 2005Applicant: Fox Hollow Technologies, Inc.Inventors: John Simpson, Himanshu Patel, Greg Stine, Brett Follmer, Michael Rosenthal, Mehrdad Farhangnia

Publication number: 20050049687Abstract: A coiled-sheet stent includes a tubular body having a longitudinal axis and a circumference, and a plurality of cylindrical bands formed in the tubular body, each band having a zig-zag pattern including a series of sequential diagonal elements connected to one another and extending about the circumference. A plurality of longitudinal connectors extend between and connect adjacent bands. The diagonal elements have an arcuate shape, all diagonal elements in each band being oriented in either a clockwise or counter-clockwise direction about the circumference. The tubular body is expandable between contracted and enlarged conditions, and the zig-zag pattern is expandable between unstretched and unstretched conditions, the zig-zag pattern being biased towards the stretched condition above a transition temperature, thereby at least partially defining the enlarged condition.Type: ApplicationFiled: October 6, 2004Publication date: March 3, 2005Inventors: Yi Yang, Farhad Khosravi, Himanshu Patel

Publication number: 20040167553Abstract: 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. In some embodiments, the cutting element is movable between retracted and deployed positions for advancing the device to a site for treatment and for removing material, respectively.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.

Patent number: 6016682Abstract: A swaging apparatus for attaching sutures to surgical needles includes at least a first die and a second die. The first die has a first member, which includes a first surface, and a second member, which includes a second surface. The second member is movable relative to the first member between an extended position, in which the second surface extends beyond the first surface, and a retracted position, in which the second surface does not extend beyond the first surface. The second die has at least one surface and is movable relative to the first die between a remote position and an adjacent position. When the second die moves relative to the first die from the remote position towards the adjacent position, the second member of the first die is caused to move from the extended position towards the retracted position, and the surfaces of the first and second dies cooperate with one another so as to swage a surgical needle positioned between the first and second dies.Type: GrantFiled: August 11, 1998Date of Patent: January 25, 2000Assignee: Ethicon, Inc.Inventors: Robert J.
