Apical ring for ventricular assist device

A method for providing an interface with the heart using an apical ring, the method comprising:

• securing an apical ring to a wall of a heart, the apical ring comprising a collar defining a central aperture that provides access into the heart through the wall;
• inserting a conduit through the central aperture;
• and
• manipulating at least two protrusions that extend laterally out from the collar to secure the conduit within the central aperture.

A method for providing an interface with the heart using an apical ring, the method comprising:

• securing an apical ring to an apex of a left ventricle of a heart, the apical ring comprising a sealing disk and a collar defining a central aperture that provides access to a portion of the apex, the collar comprising a first end and a second end separated by an axial gap;
• inserting an inflow conduit into the central aperture;
• and
• pivoting a lever coupled with the second end of the collar from an open position to a closed position to reduce the size of the axial gap.

A method of using an apical ring, the method comprising:

• providing an apical ring, the apical ring comprising:
• a sealing disk;
• a collar defining a central aperture that provides access to a portion of the wall of the heart, the collar comprising an axial gap defined by a first end and a second end;
• a clamp configured to close the axial gap, the clamp comprising a push tab and a thumb tab;
• securing the apical ring to a portion of a heart;
• inserting an inflow conduit through the central aperture;
• and
• pivoting a lever of the clamp to progressively move the first end and the second end closer to each other and reduce the size of the axial gap to secure the inflow conduit within the central aperture.
