  • Patent number: 6607505
    Abstract: A catheter assembly having a sheath, which includes a side wall enclosing an interior bore, and a distal region. The assembly also has a bendable catheter tube, which is carried for sliding movement in the interior bore. A pull wire also runs through the interior bore of the sheath, preferably within a lumen. The catheter tube has a distal portion with a coupling which joins the distal portion of the catheter tube and the distal portion of the pull wire. Relative movement of the pull wire and the sheath causes bending of the catheter tube outwardly through the opening, in response to sliding movement of the catheter tube within the interior bore toward the distal region of the sheath.

  • Publication number: 20030120271
    Abstract: Systems and methods for reducing the number of temperature measurement wires in multiple temperature sensor ablation systems are described. In a preferred embodiment, temperature sensors capable of measuring the temperature of body tissue and transmitting the temperature data digitally are incorporated in a catheter or probe ablation system that also includes electrodes in operative contact with the sensors. The sensors are connected in parallel to a common electrical bus, thereby allowing the system to operate using a reduced number of electrical paths as compared to conventional ablation systems. The present invention is also directed to ablation systems that incorporate analog sensors rather than digital sensors. In this embodiment, the system utilizes digital switching, filtering circuits, or oscillators to reduce the number of wires required to operate the sensors.

  • Patent number: 6540743
    Abstract: A coil electrode for use in an electrophysiology probe includes a first material having a relatively high radiopacity and a second material having a relatively high resiliency. This combination provides the necessary levels of durability, resiliency and radiopacity. An electrophysiological probe includes a support structure, at least one first electrode defining a first radiopacity supported on the support structure and at least one second electrode defining a second radiopacity supported on the support structure, the second radiopacity being greater than the first radiopacity. When viewed under a fluoroscope, the pattern of electrodes of varying radiopacities allows the physician to distinguish between individual electrodes.

  • Publication number: 20020161422
    Abstract: A catheter assembly comprising a elongated, flexible support structure having an axis. The assembly also includes an elongated porous electrode assembly carried by the support structure along the axis for contact with tissue. The elongated porous electrode assembly comprises a wall having an exterior peripherally surrounding an interior area, a lumen to convey a medium containing ions into the interior area, and an element coupling the medium within the interior area to a source of electrical energy. At least a portion of the wall comprising a porous material is sized to allow passage of ions contained in the medium to thereby enable ionic transport of electrical energy through the porous material to the exterior of the wall to form a continuous elongated lesion pattern in tissue contacted by the wall. The support structure can have a curvilinear geometry, e.g., a loop shape, and the elongated porous electrode assembly conforms to the curvilinear geometry.
