Patent ID: 7824358

Claim:
A heart assist device connection system, comprising: an inflow connector in fluid-tight communication with an inflow section of a heart assist device and configured to be releasably connected to an inlet extension inserted into a patient's ventricle, the inflow connector defining a longitudinal axis parallel with a flow path through the inflow connector and having a plurality of recesses defining axes substantially parallel to the inflow connector longitudinal axis and configured to receive and match a protrusion on the inlet extension when the inlet extension is inserted in the inflow connector and to prevent rotation of the inlet extension relative to the inflow connector; and an outflow connector in fluid-tight communication with an outflow section of the heart assist device and configured to be releasably connected to a conduit attached to the patient's vasculature, wherein the inflow connector includes a stopping surface to engage the inlet extension so as to block insertion of the inlet extension into the inflow connector and to define a maximum depth of insertion of the inlet extension into the inflow connector, and wherein the recesses are defined to prevent rotation of the inlet extension relative to the inflow connector from initial insertion of the inlet extension into the inflow connector to the maximum depth of insertion.
