Abstract: Some systems and methods for treating heart tissue may include instruments for intermittently occluding the coronary sinus using a coronary sinus occlusion catheter device. In some embodiments, the coronary sinus occlusion catheter can be used before or during a coronary intervention procedure in which a blockage in a heart is repaired or removed.

Abstract: Some systems and methods for operating a vessel occlusion catheter may include a control and inflation device to control the filling of the balloon in such a manner that the vessel wall will not be overstressed while the safe occlusion of the blood vessel is achieved.

Abstract: Some embodiments of a system or method for treating heart tissue can include a control system and catheter device operated in a manner to intermittently occlude a heart vessel for controlled periods of time that provide redistribution of blood flow. In particular embodiments, the system can be configured to provide an estimation of the cumulative effects of the treatment. For example, some embodiments of the system or method can treat myocardium that is at risk of infarction by intermittently altering blood flow in a venous system to induce microcirculation within the myocardium, and can output a cumulative dosage value indicative of a measurement of progress of reducing an infarct size.

Abstract: Some embodiments of a system or method for treating heart tissue can include a control system and catheter device operated in a manner to intermittently occlude a heart vessel for controlled periods of time that provide redistribution of blood flow. In particular embodiments, the system and methods may be configured to monitor at least one input signal detected at a coronary sinus and thereby execute a process for determining a satisfactory time period for the occlusion of the coronary sinus. In further embodiments, after the occlusion of the coronary sinus is released, the control system can be configured to select the duration of the release phase before the starting the next occlusion cycle.

Abstract: A method and device to assist the performance of a heart with at least one pump that is formed as a rotary pump and driven via magneto coupling. The pump includes a magnetically driven rotor rotatable within a surrounding rotor housing to act upon blood flowing from an inflow tube toward the magnetically driven rotor, and a second magnetic device axially aligned with the inflow tube and positioned to magnetically drive rotation of the magnetically driven rotor via the magneto coupling.

Abstract: In a catheter (2) to assist the performance of a heart (1) with at least one pump (7), the pump is formed as a rotary pump at the distal end of the catheter (2), the rotor (6) lying distally on the outer side being coupled via a magneto coupling with a drive wheel (21), formed as a hydraulically or pneumatically operated paddle wheel, arranged inside the catheter (2). The driving fluid is supplied to the paddle wheel via a lumen (22) of the catheter (2) and is carried off via a further lumen (23) of the catheter.
