    Abstract: A catheter with ablation and potential sensing capabilities is adapted for outer circumferential contact with an opening of a tubular region and inner circumferential contact within the tubular region. The catheter has a proximal electrode assembly and a distal electrode assembly for ablation of an ostium and potential sensing inside the pulmonary vein so that it is possible to obtain ECG signals inside a pulmonary vein when ablating around the ostium. The distal electrode assembly has an elongated member defining a longitudinal axis and a plurality of spines surrounding the member and converging at their proximal and distal ends, where each spine has at least one electrode and a curvature so that the spine bows radially outwardly from the member. The proximal electrode assembly has a proximal electrode assembly has an elongated member configured with a generally radial portion and a generally circular portion generally transverse to the catheter axis, where the generally circular portion comprising a plurality of electrodes. The control handle advantageously allows a user to manipulate a tensile member for changing the curvature of the spine.

    Abstract: A forceps includes an end effector assembly. The end effector assembly includes first and second jaw members. At least one of the jaws is moveable with respect to the other between a spaced-apart position and at least one approximated position for grasping tissue therebetween. At least one of the jaw members is adapted to connect to a source of energy for sealing tissue disposed between the jaw members. A chamber is defined within and extends longitudinally along at least one of the jaw members. The chamber is configured to retain a fluid therein and includes a series of apertures disposed on a tissue-facing surface thereof such that, upon application of energy to the jaw member(s), fluid within the chamber is heated to thermally expand within the chamber and forcefully exit the apertures to divide tissue disposed between the jaw members.

    Abstract: Electric field delivery and ablation of target tissue regions, including cancerous cells and solid tumors. Methods and systems include delivering an electric field to a target tissue, and may include positioning a first electrode or plurality to at least partially define a first treatment volume in the target tissue; positioning a second electrode or plurality to at least partially define a second treatment volume, the first volume is disposed in the second volume; and establishing a first current flow extending through the first volume and a second current flow extending through the second volume.

    Abstract: An ultrasound system has an ultrasound transducer having a transducer housing and a horn provided at the distal end of the transducer housing, an ultrasound transmission member, a sonic connector that is connected to the horn and the proximal end of the ultrasound transmission member, and a catheter knob having a proximal end that is coupled to the distal end of the transducer housing. The catheter knob has a proximal bore that houses the sonic connector. The system also includes a nesting piece that is retained inside the proximal bore of the catheter knob. The nesting piece can be moved from a first position where the sonic connector is received inside the nesting piece to a second position where the sonic connector is separated from the nesting piece when ultrasound energy is being propagated through the ultrasound transmission member.
