Systems and methods for volume reduction

A ventricular chamber volume reduction system, comprising:

• a frame comprising an anchor extending radially from the frame;
• a container body deliverable into a portion of a ventricular chamber, and wherein the container body is expandable from a first shape to a second shape when delivered into the ventricular chamber, the container body having a tissue surface in contact with a wall of the ventricular chamber and an exposed surface facing into the volume of the ventricular chamber not occupied by the container body, and wherein the exposed surface substantially spans across the ventricular chamber, wherein the container body comprises a fillport, and wherein the container body is attached to the frame, and
• a port and a port cover on the port, wherein the port cover is coplanar with an outer surface of the container body surrounding the port, and wherein the port cover is configured such that the side of the port cover facing the same direction as the outer surface is facing is configured to receive the filler.
