Connecting element for mounting a blood pump or a cannula on a heart

A system comprising:na connecting element for connecting a blood pump or a cannula to a heart, the connecting element comprising a sealing element designed to at least temporarily close an opening formed in a cardiac wall of the heart and to be opened via insertion of a cylindrical object in the direction of an axis of the opening, and comprising an anchoring element for permanent attachment of the connecting element on a cardiac muscle of the heart, wherein the connecting element further comprises a connector ring for connection to at least one of the heart or a suture ring; anda tool for forming the opening in the heart, wherein the tool comprises a first component and at least one blade, which are displaceable in a longitudinal direction of the tool relative to one another and relative to the rest of the tool, and wherein at least the sealing element of the connecting element is disposable in a front region of the tool for forming the opening in the heart, in such a way that the sealing element of the connecting element is opened when pressed by the first component of the tool and, subsequently, permits the blade of the tool for forming the opening in the heart to pass through the sealing element, wherein the tool for forming the opening in the heart comprises a sliding element, which forms a contact surface for the sealing element and is displaceable in the longitudinal direction of the tool in order to push the sealing element into the connector ring.

The system of 1, wherein at least one of the sealing element or the connector ring comprise at least one detent element, wherein the sealing element can be locked with the connector ring by way of the detent element.

A system comprising:na connecting element comprising a sealing element configured to at least temporarily close an opening formed in a cardiac wall of a heart, the sealing element further configured to be opened via insertion of an object in a direction of an axis of the opening, the connecting element further comprising an anchoring element configured to attach the connecting element to a cardiac muscle of the heart, wherein the connecting element further comprises a connector ring; anda tool for forming the opening in the heart, wherein the tool for forming the opening in the heart comprises a first component and at least one blade, which are displaceable in a longitudinal direction of the tool relative to one another and relative to the rest of the tool, and wherein at least the sealing element of the connecting element is disposable in a front region of the tool in such a way that the sealing element of the connecting element is opened when pressed by the first component of the tool and, subsequently, permits the at least one blade of the tool to pass through the sealing element, wherein the tool for forming the opening in the heart comprises a sliding element that forms a contact surface for the sealing element and is displaceable in the longitudinal direction of the tool in order to push the sealing element into the connector ring.
