| Number | Title | Issue Date |
| 7637903 | Catheter articulation segment with alternating cuts An articulation segment for a catheter includes a tube formed with a first plurality of axially aligned slits that are respectively oriented in planes perpendicular to the axis, with each slit extending azimuthally in an arc partway around the axis. The tube is also... | 12/29/2009 |
| RE40868 | Refrigeration source for a cryoblation catheter A catheter-based system for performing a cryoablation procedure uses a precooler to lower the temperature of a fluid refrigerant to a sub-cool temperature (−40° C.) at a working pressure (400 psi). The sub-cooled fluid is then introduced into a supply line of the... | 08/11/2009 |
| 7374553 | System for bi-directionally controlling the cryo-tip of a cryoablation catheter A bi-directional system for actively deflecting the distal tip of a catheter includes a reconfigurable tube that is positioned proximal to the catheter's distal tip. The tube is formed with slits that are arranged to allow the tube to be transformed from a relaxed, ... | 05/20/2008 |
| 7357797 | System and method for varying return pressure to control tip temperature of a cryoablation catheter A cryoablation device having a temperature control system includes an elongated catheter tube that has a central lumen and is formed with a closed distal tip. The distal end of a refrigerant supply line is positioned in the central lumen and distanced from the cathe... | 04/15/2008 |
| 7285108 | Active system for deflecting a distal portion of a catheter into a hoop configuration An active system for deflecting a distal portion of a catheter into a hoop configuration includes an elongated catheter body having a proximal portion and a distal portion that is formed with a lumen. A thin-walled tube, which is typically made of a metallic materia... | 10/23/2007 |
| 7252663 | Device and method for the creation of a circumferential cryogenic lesion in a pulmonary vein A device and method for ablating tissue includes a sheath system with an occlusion structure. In certain embodiments, arrhythmias originating in pulmonary veins are treated cryogenically. ... | 08/07/2007 |
| 7195625 | Catheter system for performing a single step cryoablation A system for cryoablating target tissue at a treatment site includes a cryo-element that is attached to the distal end of a cryo-catheter. An annular shaped balloon is attached to a cylindrical shaped sleeve and the sleeve is slideably mounted over the cryo-catheter... | 03/27/2007 |
| 7163535 | System for detecting leaks and occlusions in a cryoablation catheter A system for detecting leaks and occlusions in a cryoablation catheter requires monitoring pressure in the catheter at the end of two predetermined time intervals. The catheter includes a catheter tube, a cryo-chamber at the distal end of the catheter, and a supply ... | 01/16/2007 |
| 7156840 | Pressure monitor for cryoablation catheter A cryoablation device having a pressure monitoring system includes an elongated catheter tube that has a central lumen and is formed with a closed distal end. The distal end of a refrigerant supply line is positioned in the central lumen and distanced from the cathe... | 01/02/2007 |
| 7004937 | Wire reinforced articulation segment A device for steering a cardiac cryoablation catheter through the vasculature of a patient includes separate first and second deflection members that connect a tip member to the distal end of a catheter tube. Importantly, the first deflection member has a first flex... | 02/28/2006 |
| 6796979 | Coaxial catheter system for performing a single step cryoablation A system for cryoablating target tissue at a treatment site includes an annular shaped balloon attached to the distal end of a first catheter. A cryo-element is attached to the distal end of a second catheter and the second catheter is disposed in the lumen of the f... | 09/28/2004 |
