Patent number: 8256428Abstract: A method for treating tissue is provided. The method comprises introducing into a patient the distal end of a catheter. The catheter comprises a catheter shaft comprising an elongated tubing having proximal and distal ends, and a distal shaft comprising a tubing having proximal and distal ends. The distal shaft carries a treatment device along a side of the distal shaft. A hinge is mounted between the distal end of the catheter shaft and the proximal end of the distal shaft. The hinge enhances the ability of the distal shaft to bend relative to the catheter shaft in a single predetermined plane A force is exerted on the distal shaft to cause at least a portion of the treatment device that is along a side of the distal shaft to contact the tissue. The tissue is treated with the treatment device.Type: GrantFiled: March 12, 2003Date of Patent: September 4, 2012Assignee: Biosense Webster, Inc.Inventors: Gerhard Hindricks, Hans Kottkamp, Bart-Jan Korteling, Benjamin D. McDaniel, Martin F. O'Sullivan, James K. Lee

Patent number: 7302285Abstract: An improved catheter is provided that is particularly useful for mapping the Purkinje fibers for potential diagnosis of ventricular fibrillation. The catheter comprises an elongated catheter body having proximal and distal ends and at least one lumen extending longitudinally therethrough. Mounted at the distal end of the catheter body is a mapping assembly having at least two spines, each having a proximal end attached at the distal end of the catheter body and a free distal end. Each spine comprises at least one electrode, preferably a tip electrode and at least one ring electrode. An irrigation tube extends through the catheter body and has an open distal end that is in communication with the outside of the distal end of the catheter body. The spines may be arranged in an expanded arrangement wherein each spine extends radially outwardly from the catheter body or in a collapsed arrangement wherein each spine is disposed generally along the longitudinal axis of the catheter body.Type: GrantFiled: December 30, 2005Date of Patent: November 27, 2007Assignee: Biosense Webster, Inc.Inventors: Kristine B. Fuimaono, Bart-Jan Korteling, Michel Haissaguerre
