Abstract

An implantable system includes a ventricular assist device (VAD), a cuff for attachment to a heart, and a latching mechanism attached to the VAD. The VAD includes an inlet cannula. The cuff defines an outward facing circumferential groove and an opening for the inlet cannula. The cuff includes a plurality of ridges disposed at least partially within the outward facing circumferential groove. The latching mechanism is reconfigurable between an unlatched configuration in which the latching mechanism accommodates insertion of the inlet cannula into the opening and a latched configuration in which the latching mechanism is engaged with the cuff to restrain the position of the inlet cannula relative to the cuff and engaged with at least one of the plurality of ridges to block rotation of the VAD relative to the cuff.
