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.

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.
