System for connecting a blood pump to a heart

A system for connecting a blood pump to a heart, the system comprising:

• the blood pump for conveying blood, wherein the blood pump further comprises a flange-shaped portion, a first tubular portion, and a second tubular portion, wherein the flange-shaped portion is between the first and the second tubular portions;
• a connector including a tubular connector portion, a distal end, a proximal end, a lumen, and a flange-shaped connector portion, the tubular connector portion extending in an axial direction between the distal end and the proximal end, the lumen for receiving the first tubular portion of the blood pump, and the flange-shaped connector portion arranged at the distal end for fastening the connector to an organ;
• and
• a locking ring;
• wherein the blood pump further comprises a first toothed portion and the connector further comprises a second toothed portion corresponding to the first toothed portion, such that the blood pump is rotationally fixed relative to the connector when the first and the second toothed portions engage in one another;
• and
• wherein the locking ring is configured to axially hold the blood pump on the connector.
