Abstract: 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.

Abstract: A catheter assembly including at least one introducer defining a passage receiving an elongate tubular member having a proximal end, a distal end, and a lumen extending between an elongate shape-imparting element received in the lumen and imparting a predetermined shape to the distal end of the elongate tubular member, when the distal end of the elongate tubular member is extended beyond a distal end of the at least one introducer. A distal end of the one-piece shape-imparting element extends from the lumen of the elongate tubular member and is anchored proximal the distal end of the at least one introducer.

Abstract: 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).

Abstract: A sleeve steering and reinforcing device (10) includes a first, elongate, helical element (12) having spaced turns (14). At least one further, elongate, helical element (16) is co-axially arranged with the first helical element (12). The at least one further helical element (16) has a plurality of spaced turns (18) wound in an opposite direction to the turns (14) of the first helical element (12) such that the turns (14, 18) of the elements (12, 16) coincide at predetermined zones (20, 22), the zones (20, 22) being arranged along lines extending parallel to a longitudinal axis of the elements.

Abstract: A catheter assembly (10) includes a handle body (12) having a proximal end (14) and a distal end. An introducer carrier (18) is displaceably arranged relative to the handle body (12). An electrode sheath component is arranged at a distal end of the handle body (12), the electrode sheath component comprising at least one pair of limbs interconnected by a bridging portion, at least the bridging portion carrying at least one electrode. An elongate shape forming component (40) is received in a lumen of the electrode sheath component, the shape forming component (40) having at least one predetermined shape formed along its length. An introducer component (22) is carried on the introducer carrier (18) of the handle body (12). The electrode sheath component is received within the introducer component (22) prior to use with at least the bridging portion of the electrode sheath component being extended out of a distal end of the introducer component (22) to be exposed for use.

Abstract: A catheter assembly (10) including at least one introducer (12) defining passage (18) receiving elongate tubular member (20) having proximal end, distal end and lumen extending between. Elongate shape imparting element (32) received in lumen and imparting predetermined shape (26) to distal end of tubular member (20) when distal end of tubular member is extended beyond distal end of introducer (12). Distal end of shape imparting element (32) extends from lumen of tubular member (20) and is anchored proximally of distal end of introducer (12).
