Patent number: 10668275Abstract: A process for manufacturing an electrical lead having one or more electrodes includes providing an elongate member having at least one polymeric region and further having at least one electrical conductor that extends along at least a part of a length of the elongate member and that is contained in a wall of the elongate member. A length of the at least one electrical conductor is accessed at the at least one polymeric region. An electrically conductive adhesive is applied to the length of the at least one electrical conductor that has been accessed.Type: GrantFiled: August 29, 2012Date of Patent: June 2, 2020Assignee: CATHRX LTDInventors: Neil L. Anderson, Norman Booth, Evan K. Chong

Patent number: 8260394Abstract: A modular catheter includes an elongate tubular member having a proximal end and a closed, distal end. A lumen extends from the proximal end to the distal end and a plurality of electrodes are arranged at, or adjacent, the distal end, conductors for the electrodes being contained within a wall of the tubular member. An elongate shape-imparting mechanism is removably received within the lumen of the tubular member such that a distal end of the shape-imparting mechanism is substantially in register with the distal end of the tubular member. A control device has a proximal end and a distal end, the proximal end of the tubular member and a proximal end of the shape-imparting mechanism being releasably connectable to the distal end of the control device.Type: GrantFiled: October 5, 2011Date of Patent: September 4, 2012Assignee: Cathrx LtdInventors: Neil L. Anderson, Evan K. Chong, Matthew J. Partlett

Patent number: 7871410Abstract: A system (10) for heating a biological site in a patient's body includes a transformer (14) having a primary winding and a secondary winding. The secondary winding has a tap (24) to provide a ground reference and two sources of radio frequency (RF) energy. An active electrode (16) is connected to each source to apply energy from its associated source to the site, the energy applied by one electrode (16) being out of phase with the energy applied by the other electrode (16).Type: GrantFiled: October 28, 2003Date of Patent: January 18, 2011Assignee: CathRx LtdInventors: Norman Booth, Evan K.
