opening a region of the heart;
affixing an access device at the opening wherein the access device comprises an apical base plate;
directing a cardiac assist unit through the access device and the opening so that at least a portion of the cardiac assist unit is positioned inside the heart; and,
sealing the cardiac assist unit at an interface of the access device and the cardiac assist unit.
2 . The method according to claim 1 , wherein the sealing includes urging the cardiac assist unit against a sealing element of the access device.
3 . The method according to claim 1 , wherein the access device has a through-port and the cardiac assist unit is directed through the through-port.
4 . The method according to claim 3 , wherein the through-port is a tube.
5 . The method according to claim 1 , wherein affixing the access device comprises fixing a flange of the access device to heart tissue.
6 . The method according to claim 1 , wherein the access device includes a sealing unit for receiving the cardiac assist unit.
7 . The method according to claim 6 , wherein affixing the access device to the heart includes attaching a sealing unit to the apical base plate.
