Abstract: Apparatus for use with an electroanatomical mapping system, an elongated needle assembly having a distal energy emitter configured to be detectable by the electroanatomical mapping system, an energy-delivery assembly having at least one sensor configured to receive, at least in part, the distal energy emitter of the elongated needle assembly in such a way that the distal energy emitter and said at least one sensor are movable relative to each other. The apparatus includes a signal-interface assembly. The signal-interface assembly includes a signal-input section configured to be signal connectable to said at least one sensor of the energy-delivery assembly. A signal-output section is configured to be signal connectable to an input section of the electroanatomical mapping system.

Abstract: Described are methods of performing perfusion on a heart having a left atrium, a right atrium, a pulmonary artery. The methods are performed on a device configured for selectively performing perfusion in at least a Langendorff mode and a right-sided working mode. The methods include performing profusion on a heart in a right-side working mode of the device in which an aortic line is open, a left atrial line is closed, and a reservoir return line is closed.

Abstract: Systems and methods for performing perfusion and contractility assessments for a heart are provided. The system can operate in any of Langendorff mode, pump-supported working mode, passive working mode, and right-sided working mode. The system includes a reservoir from which one or more pumps are operable to supply a heart with fluids and collect fluids output therefrom. One or more clamps can be used to switch between Langendorff, pump-supported, passive, and right-sided working modes.
