Publication number: 20140276782Abstract: A catheter system that includes a catheter element sized to pass through blood vessels to an organ of an animal. The distal end portion of the catheter element is capable of assuming and maintaining a curved configuration. A medical element is disposed with respect to the catheter element so as to interact therewith, the medical element being capable of assuming and maintaining a curved configuration. At least one ablating or mapping tool is disposed on the distal end portion of either the medical element or the catheter element, or both, for either mapping or ablating tissue in the organ when the distal end portion of the catheter system is disposed in the organ. The catheter system can include a hand grip for controlling the catheter system.Type: ApplicationFiled: March 15, 2013Publication date: September 18, 2014Inventor: LARRY D. PASKAR

Publication number: 20140088684Abstract: A catheter system and method that includes a catheter element sized to pass through blood vessels to an organ of an animal. A medical element can be disposed with respect to the catheter element so as to interact therewith, the medical element being capable of assuming and maintaining a curved configuration. An ablating or mapping tool can be disposed on either the medical element or the catheter element, or both. The catheter system can be used for inserting a stent graft limb branch into a stent graft body disposed in a living being, the stent graft body having a trunk and an opening for receiving said branch. A guide element is inserted through a vessel of the living being to the vicinity of the branch receiving opening of the stent graft body. The catheter system can include a hand control for manipulating the catheter system.Type: ApplicationFiled: November 30, 2013Publication date: March 27, 2014Inventor: LARRY D. PASKAR

Patent number: 7794424Abstract: A transformable catheter includes a sheath having a length which is a substantial fraction of the entire length of the transformable catheter and a bore therethrough. A preformed inner catheter having a complex curve formed into the distal end thereof is disposed in the sheath bore. By axially moving the inner catheter with respect to the sheath, various tip shapes may be achieved. At least one wire runs from the proximal end of the sheath to the vicinity of the distal end of the sheath to selectively deflect the distal tip of the sheath as desired by the user to assist in reformation and transformation of the tip of the catheter. By suitable manipulation of the wire and of the inner catheter with respect to the sheath, the shape of the exposed portion of the distal end of the inner catheter may be transformed to any of a variety of shapes.Type: GrantFiled: August 16, 2001Date of Patent: September 14, 2010Inventor: Larry D.

Patent number: 5304131Abstract: A medical tube has at least one wire running from the proximal end to the vicinity of the distal end thereof, which wire is connected to the tube adjacent the distal end so as to allow the distal tip to be deflected upon movement of the wire. The tube has gaps therein on one side of its longitudinal axis so as to form a predetermined region of weakness, whereby upon tension being applied to the wire the distal end of the tube bends in the direction of the predetermined region of weakness. The medical tube may be a sheath in which is disposed a preformed inner catheter having a complex curve formed into the distal end thereof. The sheath is sufficiently rigid and the inner catheter is sufficiently pliable so that withdrawal of the inner catheter into the sheath substantially straightens out the portion of the complex curve of the distal tip disposed within the sheath.Type: GrantFiled: February 11, 1992Date of Patent: April 19, 1994Inventor: Larry D.
