Heart pump cuff

A heart pump system comprising:

• a base comprising a first rigid conduit and a first flexible layer, the first flexible layer being directly coupled with a proximal end of the first rigid conduit, wherein the first rigid conduit defines a channel;
• and
• a port configured to couple with a heart pump, the port comprising a second rigid conduit, wherein the port is coupled to the base such that a lumen of the second rigid conduit is in alignment with the channel, the port comprising a lip that is configured to engage with the base, wherein the port further comprises a second flexible layer and wherein the port is coupled to the base with a stitching disposed between the second flexible layer and the first flexible layer;
• wherein the second flexible layer is directly coupled with a proximal side of the lip of the port such that the second flexible layer is disposed in between the lip of the port and the heart pump when the heart pump is coupled with the port.

A heart pump system comprising:

• a base comprising a first rigid conduit and a first flexible layer, the first flexible layer mechanically coupled with a proximal end of the first rigid conduit, wherein the first rigid conduit defines a channel, and wherein:
• the first rigid conduit comprises an inner surface, an outer surface, a central axis, and a distal end, and
• the inner surface of the first rigid conduit tapers away from the central axis of the first rigid conduit and toward the outer surface of the first rigid conduit at the distal end of the first rigid conduit to form a beveled distal edge of the first rigid conduit;
• and
• a port comprising a second rigid conduit and a second flexible layer, wherein the second flexible layer is coupled with the first flexible layer such that a lumen of the second rigid conduit is in alignment with the channel defined by the first rigid conduit, the port further comprising an engagement feature that is configured to couple with a corresponding mating feature of a heart pump.
