A catheter sheath comprises a tubular member connected to a catheter handle, the tubular sheath including one or more electrical conductors and one or more electrode rings attached to the tip of the tubular member. The tubular member further includes at least one opening that allows the one or more electrical conductor to be electrically connected to the one or more electrode rings. The electrode ring is slid over the tubular member so as to cover the opening. The tubular member and the electrode ring are subjected to heat treatment by induction heating so that the material of the tubular member melts locally around the electrode ring to form a seal between the tubular member and the electrode ring.

Method of manufacturing a catheter sheath

A steerable stylet assembly includes a tubular member defining a passage, the tubular member defining a first bend enhancing region. At least one further bend enhancing region is arranged intermediate the first bend enhancing region and a distal end of the tubular member. A first actuator is received in the passage of the tubular member, a distal end of the first actuator being fast with the tubular member at a first termination so that relative axial movement between the tubular member and the first actuator causes deflection at the first enhancing region. A second actuator is received in the passage of the tubular member, a distal end of the second actuator being fast with the tubular member at a second termination so that relative axial movement between the tubular member and the second actuator causes the distal part of the tubular member to be formed into a desired shape. The assembly includes a control mechanism to control relative axial movement between the tubular member and each of the actuators.

A shape-imparting mechanism for a catheter that includes an elongate element dimensioned to fit within a lumen of an electrode sheath of a catheter. An insertion facilitating arrangement is carried at a distal end of the elongate element for facilitating insertion of the distal end of the elongate element into the lumen of the electrode sheath of the catheter.

Shape-imparting mechanisms for catheter assemblies

A catheter handle includes a handle body. A steering control mechanism is displaceably carried on the handle body. An electrode sheath carrier is carried on the handle body, the electrode sheath carrier being displaceable at least relative to the steering control mechanism.

Catheter handle and a catheter assembly including such a handle

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

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.

Modular catheter

A catheter steering mechanism includes a tubular member defining a passage. The tubular member has a longitudinally extending cutaway portion defining a bend-enhancing region formed at a predetermined location along a length of the tubular member. An actuator is received in the passage of the tubular member, a distal part of the actuator being fast with a distal part of the tubular member. A restraining arrangement is defined by the tubular member, the restraining arrangement comprising a structure arranged at the bend-enhancing region to retain the actuator substantially within the confines of the tubular member during bending.
