In one general aspect, a cuff for attachment to a heart includes an attachment component configured to engage a blood pump to attach the cuff to the blood pump and a sewing ring for attachment to the heart. The sewing ring is coupled to the attachment component, and the attachment component and the sewing ring each define a central opening configured to admit an inflow cannula of a blood pump. The sewing ring comprises a member that provides rigidity to flatten a portion of a myocardium of the heart when the cuff is attached to the heart.

An apparatus for protecting heart tissue from an implanted inlet element of a blood pump. The apparatus includes a flange member having a first radially constricted configuration and a second radially expanded configuration, the flange member being biased in its second radially expanded configuration. The flange member defines an opening there through sized to receiving the inlet element of the blood pump. A retaining element extending from the flange member is included, the retaining element being flexible and sized to be disposed about at least a portion of the inlet element.

An implantable anastomotic assembly, which is configured to be attached to cardiovascular tissue, includes a connection interface, a plurality of outer plates, and a plurality of connectors configured to extend between and interconnect the connection interface and the plurality of outer plates, respectively, according to various embodiments. The connection interface is separate from and non-contiguous with the plurality of outer plates, according to various embodiments.

A synchronous drive system for simultaneously driving more than two or more rotational tissue screws and a method for simultaneously affixing a medical device to tissue employing the synchronous drive system. The synchronous drive system is particularly configured to affix an apical cuff to cardiac muscle tissue by simultaneously driving a plurality of rotational tissue screws through the apical cuff and into cardiac muscle tissue thereby affixing the apical cuff to the cardiac muscle tissue.
