Kilpatrick Townsend & Stockton LLP
Ventricular cuff
An implantable system includes a ventricular assist device and a cuff for attachment to a heart. The ventricular assist device includes an inlet cannula. The cuff defines an opening for insertion of the inlet cannula into the opening. The cuff includes an annular fastening member and an attachment member. The annular fastening member is configured to be sutured to heart tissue. The attachment member includes flexible extensions. Each of the flexible extensions is configured to interface with the inlet cannula during insertion of the inlet cannula into the opening so as to cause the flexible extension to flex outward to accommodate passing of the inlet cannula along the opening. Each of the flexible extensions is configured to interface with the inlet cannula to impede extraction of the inlet cannula from the opening.
