Abstract
An apparatus for protecting heart tissue from an implanted inlet element of a blood pump. The apparatus includes a flange member having a first radially constricted configuration and a second radially expanded configuration, the flange member being biased in its second radially expanded configuration. The flange member defines an opening there through sized to receiving the inlet element of the blood pump. A retaining element extending from the flange member is included, the retaining element being flexible and sized to be disposed about at least a portion of the inlet element.

An apparatus for protecting the heart from an implanted inlet element of a blood pump comprising:
- a flange member having a first radially constricted configuration and a second radially expanded configuration, the flange member being biased in its second radially expanded configuration, the flange member defining an opening there through sized to receiving the inlet element of the blood pump;
- and
- a retaining element extending from the flange member, the retaining element being flexible and sized to be disposed about at least a portion of the inlet element.
A method implanting an apparatus for protecting the heart from an implanted inlet element of a blood pump comprising:
- advancing a flange member in a radially constricted configuration through an opening of a heart wall, the flange member including a retaining element defining a tubular body extending proximally out of the heart through the opening, the flange member being configured to transition to a radially expanded configuration after passage through the opening of the heart wall;
- and
- positioning the flange member and the retaining element to overlie an interior surface of the heart wall surrounding the opening.
An apparatus for protecting the heart from an implanted inlet element of a blood pump comprising:
- a flange member having a first radially constricted configuration and a second radially expanded configuration, the flange member being biased in its second radially expanded configuration, the flange member defining an opening there through sized to receiving the inlet element of the blood pump, the flange member defining an annular pocket and including a flexible washer disposed within the annular pocket, the flexible washer including a plurality of radially disposed ribs and apertures;
- and
- a retaining element extending proximally from the flange member, the retaining element being flexible and radially disposed about the opening, the retaining element defining a tubular body defining a plurality of tearable strips, the tubular body defining a lumen coaxial with the opening of the flange member.
