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.

Electrical leads for medical use

An irrigation catheter assembly comprises an electrode sheath mount for mounting an electrode sheath. The mount has a laterally arranged aperture defined in it through which conductors for electrodes of the electrode sheath pass, in use. A connector, to which a source of irrigation fluid is connectable, is connected to a proximal end of the electrode sheath mount. The connector communicates with an interior of the mount so that, in use, fluid passes through the lumen of the electrode sheath to be delivered to a distal end of the electrode sheath.

A steering mechanism for a catheter includes a tubular member defining a passage. The tubular member has a longitudinally extending, bend-enhancing portion formed at a predetermined region of the tubular member. An actuator is received in the passage of the tubular member, with the distal part of the actuator being fastened to a distal part of the tubular member.

Steerable catheter

Process of manufacturing a medical use electrical lead

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.

A system () for heating a biological site in a patient's body includes a transformer () having a primary winding and a secondary winding. The secondary winding has a tap () to provide a ground reference and two sources of radio frequency (RF) energy. An active electrode () is connected to each source to apply energy from its associated source to the site, the energy applied by one electrode () being out of phase with the energy applied by the other electrode ().

An ablation catheterincludes an elongate carrier. A first loopis arranged at, or adjacent, a distal end of the carrier. At least one sensing electrodeis carried on the first loopfor sensing irregular electrical activity in a patient's body. At least one further loopis arranged proximally relative to the first loopon the carrierin a fixed orientation relative to the first loop. At least one ablating electrodeis carried on the second loopfor ablating a site of the patient's body where irregular electrical activity occurs.

Ablation catheter

Component of a handle portion of a catheter

An ablation catheter () includes an elongate carrier (). A first loop () is arranged at or adjacent a distal end of the carrier (). At least one sensing electrode () is carried on the first loop () for sensing irregular activity in a patient's body. At least one further loop () is arranged proximally relative to the first loop () on the carrier () in a fixed orientation relative to the first loop (). At least one ablating electrode () is carried on the second loop () for ablating a site of the patient's body where irregular electrical activity occurs. In another form of the invention, the ablation catheter includes a carrier () having a loop () defined at the distal end, the loop () comprising a first arm () and a second arm (), the arms () of the loop () being at least partly electrically isolated with respect to each other and at least one electrode () arranged on each arm () of the loop (). In either form of the invention, an ablating electrode () carried on an outer periphery of the carrier () may be arranged only partially about the periphery of the carrier ().
