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

Patent number: 6027514Abstract: An atherectomy catheter includes a catheter body having a blade assembly at its distal end. The blade assembly includes first blade and a second blade, where each blade has an opposed cutting edge. At least one of the cutting edges will have a penetrating point formed thereon. Preferably, both edges will have at least one aligned cutting point, more preferably at least two or more aligned cutting points. When the blades are actuated to shear tissue therebetween, the cutting points act to penetrate and capture the material to be sheared.Type: GrantFiled: December 17, 1997Date of Patent: February 22, 2000Assignee: Fox Hollow Technologies, Inc.Inventors: John G.

Patent number: 5352197Abstract: The present invention is a turn limiter for a catheter with a twistable tip. The catheter having a flexible wall for use in complex twisting anatomy contains a torque wire or a torquable guide wire lumen. The torque wire or torquable guide wire lumen extends through the length of the catheter and is attached to the catheter at or near the distal end thereof. The proximal end of the torque wire protrudes from the proximal end of the catheter and is attached to a turn limiter. Rotation of the turn limiter imparts a torque to the torque wire or torquable guide wire lumen. The turn limiter allows limited rotation of the proximal end of the torque wire or torquable guide wire lumen without axial dislocation. The turn limiter may have a feature for indicating the amount of torque applied to the torque element.Type: GrantFiled: March 12, 1993Date of Patent: October 4, 1994Assignee: The Spectranetics CorporationInventors: Dan J.
