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. (FIG. 2).

(canceled)
A device for assisting performance of a heart, comprising:
- a pump for conveying a fluid in one or more blood vessels;
- a control circuit configured to regulate a conveyed quantity of said fluid;
- and
- a heart ventricle catheter having one or more sensors in communication with the control circuit to supply measurement values indicative of cardiac output, wherein the control circuit is configured to regulate the conveyed quantity of said fluid as a function of said measurement values of the one or more sensors of the heart ventricle catheter, and wherein the pump is formed as an intravasal rotary pump on a periphery or at a distal end of the catheter, and a rotor of the pump is arranged on an outer side of the catheter, is supported by a central shaft configured to rotate with the rotor, and is connected via a magneto coupling with a drive which is arranged inside the catheter.
