    Abstract: Actuators for steerable medical devices are disclosed that not only deflect or steer a portion of a medical device (e.g., a distal portion of a catheter shaft), but also include mechanisms for actively returning the deflected portion of the medical device to an initial configuration (e.g., straight or substantially straight). These active return-to-straight mechanisms may return a catheter shaft from a deflected configuration to a substantially straight configuration throughout a medical procedure, may employ one or more tension members extending along the catheter shaft, and may comprise a gross return actuator and a fine return actuator. For example, the gross return actuator may be configured to partially reverse the deflection of the distal portion of the catheter; and the fine return actuator may be configured to continue reversing the deflection. The gross return actuator may automatically trigger or actuate (mechanically or electromechanically) the fine return actuator.

    Abstract: Deflection actuators configured to provide variable mechanical advantage and to optionally maintain a desired state of deflection are disclosed. Each deflection actuator may comprise a plurality of planar components, at least one of which is adapted to move relative to at least one other component. The planar components may comprise a channeled platform and a pivotable base mounted adjacent to the channeled platform. The platform may comprise a slider trough to slidably retain a slider. The base may have a cam arm pivotally connected to it and adapted to push a slider in its trough, whereby pivoting of the pivotable base relative to the channeled platform produces linear motion by the slider in its slider trough. The deflection actuator may also comprise a friction-lock knob, a knob receiver, and a pivot hub to selectably produce friction between various components to hold a catheter shaft in a desired state of deflection.

    Abstract: An electrode assembly includes an electrode pair including a first electrode and a second electrode configured to be selectively energized for delivery of electroporation therapy. The electrode assembly also includes an expandable isolation member disposed axially between the first electrode and the second electrode. One of the first electrode and the second electrode is positioned proximally of a proximal end of the expandable isolation member and the other of the first electrode and the second electrode is positioned distal to a distal end of the expandable isolation member. The expandable isolation member is configurable between a collapsed configuration and an expanded configuration. The expandable isolation member includes a circumferential sealing surface configured for sealing engagement with tissue of a patient such that the expandable isolation member inhibits fluid and electrical communication between the first electrode and the second electrode when engaged with the tissue.
