Abstract: A two-piece electrode cuff to stimulate a nerve is provided. The cuff is arranged to adapt it to the natural form of the nerve as well as to the surrounding tissues. The shape of the electrode cuff is optimized for ease of placement and it assures that the device will remain in place without major displacement and will minimize the damage to the nerve post-implant.

Abstract: A system to perform electroporation ablation of target tissue in a chamber of a patient's heart, the system comprising a catheter and a controller. The catheter includes an electrode assembly having a plurality of ablation electrodes, wherein the catheter is adapted to position the electrode assembly in contact with the target tissue. The controller is configured to identify, from among the plurality of ablation electrodes, a first subset of ablation electrodes that are in contact with the target tissue, and a second subset of ablation electrodes that are not in contact with the target tissue, and to apply a pulsed electrical signal to the first subset of ablation electrodes and not to the second subset of ablation electrodes.

Abstract: A medical device for use with a catheter assembly including an elongated catheter coaxially disposed within a sheath is disclosed. The medical device includes a deformable tube having a proximal end, a distal end, an outer wall with an outer diameter, and an inner wall forming an axial lumen. The distal end attaches to the sheath, and the proximal end receives the catheter into the lumen. The medical device also includes a opposing paddles disposed against the outer wall, each of the opposing paddles having a generally planar lock region to be disposed against outer wall at the outer diameter, the lock surface tangential to the deformable tube.

Abstract: A system for facilitating an ablation in a patient's heart is disclosed. The system includes a catheter and a controller. The catheter includes an electrode assembly having spaced-apart electrodes disposed on splines to generate an electric field in the heart, the splines configurable in an expanded position wherein the plurality of spaced-apart electrodes are in a selected spatial relationship, and wherein the splines are deformable relative to the expanded configuration when subjected to a force. The controller is configured to measure an electrical signal received from an electrode of the spaced-apart electrodes in response to the electric field, the electrical signal indicative of a parameter of the electric field, and the controller configured to determine a deformation of the splines relative to the expanded position based on the measured electrical signal.

Abstract: A system for performing electroporation ablation of target tissue in a chamber of a patient's heart is disclosed. The system including a catheter including an electrode assembly having a plurality of electrodes, wherein the catheter is adapted to position the electrode assembly at a plurality of locations proximate the target tissue, a graphical display, and a controller. The controller configured to generate, on the graphical display, a graphical representation of the electrode assembly. The controller configured to generate, on the graphical display, a graphical representation of a model of electric fields generated in response to delivery of pulsed electrical signals to selected ones of the plurality of electrodes.
